<p>Actins are a family of highly conserved cytoskeletal proteins that play fundamental roles in nearly all aspects of eukaryotic cell biology. The ability of a cell to divide, move, endocytose, generate contractile force, and maintain shape is reliant upon functional actin-based structures. Actin isoforms are grouped according to expression patterns: muscle actins predominate in striated and smooth muscle (e.g., ACTA1, <a href="/entry/102610">102610</a>, and ACTA2, <a href="/entry/102620">102620</a>, respectively), whereas the 2 cytoplasmic nonmuscle actins, gamma-actin (ACTG1) and beta-actin (ACTB; <a href="/entry/102630">102630</a>), are found in all cells (<a href="#13" class="mim-tip-reference" title="Sonnemann, K.

All showed postlingual, bilateral, symmetric, progressive sensorineural hearing loss at mid and high frequencies. In yeast, the E241K mutation resulted in a severe phenotype characterized by a highly compromised ability to grow on glycerol as a carbon source, an aberrant multivacuolar pattern, and deposition of thick F-actin bundles randomly in the cell. The latter feature is consistent with the unusual tendency of the E241K mutant to form bundles in vitro, although this propensity to bundle was neutralized by tropomyosin (TPM1; <a href="/entry/191010">191010</a>) and the E241K filament bundles were hypersensitive to severing in the presence of cofilin (CFL1; <a href="/entry/601442">601442</a>).

<span class="mim-text-font">
<p>Actins are a family of highly conserved cytoskeletal proteins that play fundamental roles in nearly all aspects of eukaryotic cell biology. The ability of a cell to divide, move, endocytose, generate contractile force, and maintain shape is reliant upon functional actin-based structures. Actin isoforms are grouped according to expression patterns: muscle actins predominate in striated and smooth muscle (e.g., ACTA1, 102610, and ACTA2, 102620, respectively), whereas the 2 cytoplasmic nonmuscle actins, gamma-actin (ACTG1) and beta-actin (ACTB; 102630), are found in all cells (Sonnemann et al., 2006). </p>

(1986) presented the complete sequence of gamma-actin mRNA. They noted that gamma- and beta-actin differ by only 4 amino acids at their conserved N-terminal ends. </p><p>By screening a promyelocytic leukemia cell line cDNA library with chicken beta-actin, Chou et al. (1987) cloned human gamma-actin. The deduced protein contains 375 amino acids. Northern blot analysis of human fetal tissues detected highest expression of a 2.35-kb transcript in brain and kidney, with weaker expression in liver and trophoblasts. High expression was also detected in a human hepatoma cell line. Expression of gamma-actin increased during macrophage differentiation in a neuroblastoma cell line. </p><p>By Northern blot analysis of mouse tissues, Erba et al. (1988) detected high gamma-actin expression in lung, kidney, and testis, moderate expression in brain, low expression in stomach, and very low expression in liver, heart, and muscle. </p>

<strong>Gene Function</strong>

</div>
<span class="mim-text-font">
<p>Loisel et al. (1999) used pure components of the actin cytoskeleton to reconstitute sustained movement in Listeria and Shigella in vitro. Actin-based propulsion was driven by the free energy released by ATP hydrolysis linked to actin polymerization and did not require myosin (see 601478). In addition to actin and activated Arp2/3 complex (see 604221), actin depolymerizing factor and capping protein (see 601571) were also required for motility as they maintained a high steady-state level of G-actin, (monomeric, or globular, actin) which controls the rate of unidirectional growth of actin filaments at the surface of the bacterium. The movement was more effective when profilin (see 176590), alpha-actinin (see 102575), and, in the case of Listeria, VASP (601703) were also included. </p><p>Tzima et al. (2000) showed that annexin V (ANXA5; 131230) bound filamentous actin (F-actin) and gamma-actin, but not beta-actin, in activated human platelets. </p><p>Interaction of phospholipase D (see PLD1; 602382) with actin microfilaments regulates cell proliferation, vesicle trafficking, and secretion. Kusner et al. (2002) found that highly purified G-actin inhibited both basal and stimulated PLD1 activity, whereas F-actin had the opposite effect. Actin-induced modulation of PLD1 activity was independent of the activating stimulus. The effects of actin on PLD1 were isoform specific: human platelet actin, which exists in a 5:1 ratio of beta- and gamma-actin, was only 45% as potent and 40% as efficacious as rabbit skeletal muscle alpha-actin. </p><p>The mammalian cytoskeletal proteins beta- and gamma-actin are highly homologous, but only beta-actin is N-terminally arginylated in vivo, which regulates its function. Zhang et al. (2010) examined the metabolic fate of exogenously expressed arginylated and nonarginylated actin isoforms. Arginylated gamma-actin, unlike beta-actin, was highly unstable and was selectively ubiquitinated and degraded in vivo. This instability was regulated by the differences in the nucleotide coding sequence between the 2 actin isoforms, which conferred different translation rates. Gamma-actin was translated more slowly than beta-actin, and this slower processing resulted in the exposure of a normally hidden lysine residue for ubiquitination, leading to the preferential degradation of gamma-actin upon arginylation. Zhang et al. (2010) suggested that this degradation mechanism, coupled to nucleotide coding sequence, may regulate protein arginylation in vivo. </p>

Compared with ATP-actin structures from complexes with deoxyribonuclease I (125505), profilin, and gelsolin (137350), monomeric ADP-actin is characterized by a marked conformational change in subdomain 2. </p>

<p><strong><em>DFNA20/26</em></strong></p><p>
Zhu et al. (2003) identified 4 families segregating an autosomal dominant progressive sensorineural hearing loss, designated DFNA20 or DFNA26 (see 604717), that had been linked to 17q25.3. They narrowed the critical interval containing the causative gene to approximately 2 million bp between markers D17S914 and D17S668, and sequenced cochlear-expressed genes within this interval in affected family members. In all 4 families, they identified missense mutations in highly conserved actin domains of the ACTG1 gene (102560.0001-102560.0004). Much of the specialized ultrastructural organization of the cells in the cochlea was based on the actin cytoskeleton. Zhu et al. (2003) noted that many of the mutations known to cause either syndromic or nonsyndromic deafness occur in genes that interact with actin. They stated that this was the first description of a mutation in cytoskeletal, or nonmuscle, actin. </p><p>In 19 affected individuals of a large Norwegian family reported by Teig (1968), Rendtorff et al. (2006) identified a heterozygous mutation in the ACTG1 gene (102560.0006). No mutations in the ACTG1 gene were identified in 19 additional Norwegian and Danish families with autosomal dominant hearing loss, suggesting that it is not a frequent cause in this population. </p><p><strong><em>Baraitser-Winter Syndrome 2</em></strong></p><p>
Riviere et al. (2012) reported 8 patients with Baraitser-Winter syndrome (BRWS2; 614582) with heterozygous missense mutations in the ACTG1 gene. Seven of 8 of these patients were proven to have de novo mutations. One mutation was recurrent in 3 patients, a ser-to-phe substitution at codon 155 (S155F; 102560.0009). All the others had novel missense mutations (102560.0010-102560.0014). Congenital or later-onset progressive hearing loss is a common feature of Baraitser-Winter syndrome, and Riviere et al. (2012) suggested that Baraitser-Winter syndrome represents the severe end of a spectrum of cytoplasmic actin-associated phenotypes that begins with Baraitser-Winter syndrome and extends to nonsyndromic hearing loss. </p>

<p>To study the role of ACTG1 in skeletal muscle development and avoid the near-certain embryonic lethality of conventional Actg1 knockout, Sonnemann et al. (2006) conditionally ablated Actg1 expression in mouse skeletal muscle. Although muscle development proceeded normally, Actg1-knockout mice presented with overt muscle weakness accompanied by a progressive pattern of muscle fiber necrosis and regeneration. The phenotype resembled human centronuclear myopathies, which are typically associated with perturbations in enzyme activity, muscle development, or excitation-contraction coupling. </p>

<p>In a Dutch family with autosomal dominant deafness linked to the DFNA20 region (604717), Van Wijk et al. (2003) found that affected members had an 833C-T transition in exon 5 of the ACTG1 gene, resulting in a thr278-to-ile (T278I) substitution. The mutation was identified in helix 9 of the modeled protein structure and was predicted to have a small but significant effect on the gamma-1 actin structure owing to its close proximity to a methionine residue at position 313 in helix 11. The authors suggested that the mutation would interfere with actin polymerization. </p>

Functional expression studies in yeast showed that the mutant protein suppressed growth; computer modeling suggested that the V370A substitution impaired hydrophobic interactions and destabilized the position of the C-terminal tail of the protein.

<p>In a Spanish father and daughter with autosomal dominant deafness (604717), Morin et al. (2009) identified heterozygosity for a 354G-C transversion in exon 3 of the ACTG1 gene, resulting in a lys118-to-asn (K118N) substitution in subdomain 1. The mutation was not found in 100 normal unrelated Spanish controls. Both father and daughter showed bilateral, symmetric, progressive sensorineural hearing loss at mid and high frequencies of postlingual onset. The daughter had onset in the third decade, and the father had even later onset. Morin et al. (2009) showed that the K118N mutation had a very mild effect in yeast. In transiently transfected NIH3T3 cells, K118N-mutant actin was normally incorporated into cytoskeleton structures, although cytoplasmic aggregates were also observed indicating an element of abnormality caused by the K118N mutation in vivo. Gene-gun mediated expression of K118N mutant in mouse cochlear hair cells resulted in no gross alteration in cytoskeletal structures or the morphology of stereocilia. Morin et al. (2009) supported the hypothesis that the postlingual and progressive nature of the DFNA20/26 hearing loss may be the result of a progressive deterioration of the hair cell cytoskeleton over time. </p>

<p>In 4 affected members of a Spanish family with autosomal dominant deafness (604717), Morin et al. (2009) identified heterozygosity for a 721G-A transition in exon 4 of the ACTG1 gene, resulting in a glu241-to-lys (E241K) substitution in subdomain 4. The mutation was not found in 100 normal unrelated Spanish controls. The affected members were referred for hearing loss at school age, with the earliest individual referred at age 6 years. All showed postlingual, bilateral, symmetric, progressive sensorineural hearing loss at mid and high frequencies. In yeast, the E241K mutation resulted in a severe phenotype characterized by a highly compromised ability to grow on glycerol as a carbon source, an aberrant multivacuolar pattern, and deposition of thick F-actin bundles randomly in the cell. The latter feature is consistent with the unusual tendency of the E241K mutant to form bundles in vitro, although this propensity to bundle was neutralized by tropomyosin (TPM1; 191010) and the E241K filament bundles were hypersensitive to severing in the presence of cofilin (CFL1; 601442). In transiently transfected NIH3T3 cells, E241K-mutant actin was normally incorporated into cytoskeleton structures, although cytoplasmic aggregates were also observed indicating an element of abnormality caused by the mutations in vivo. Gene-gun mediated expression of the E241K mutant in mouse cochlear hair cells resulted in no gross alteration in cytoskeletal structures or the morphology of stereocilia. Morin et al.

<p>In 3 unrelated individuals with Baraitser-Winter syndrome-2 (BRWS2; 614583), Riviere et al.

This mutation was proven to have occurred de novo in 2 of the 3; in the third, parental DNA was not available. One of these 3 patients, LP98-096, was reported by Baraitser and Winter (1988). This mutation was not identified in 224 control exomes. Riviere et al. (2012) studied lymphoblastoid cell lines from individuals carrying the S155F mutation and demonstrated that these had increased F-actin content and multiple, anomalous F-actin-rich filopodia-like protrusions compared to control cells, resulting in increased cell perimeter. Cell lines also showed increased sensitivity to treatment with latrunculin A. </p>

To ensure long-term funding for the OMIM project, we have diversified
our revenue stream. We are determined to keep this website freely
accessible. Unfortunately, it is not free to produce. Expert curators
review the literature and organize it to facilitate your work. Over 90%
of the OMIM's operating expenses go to salary support for MD and PhD
science writers and biocurators. Please join your colleagues by making a
donation now and again in the future. Donations are an important
component of our efforts to ensure long-term funding to provide you the
information that you need at your fingertips.
