However, DNAJB6 appeared more in the periphery of the protein accumulations, in contrast to more pronounced colocalization seen in myotilinopathies. Three of the mutations resulted in a phe93-to-leu (F93L) substitution at a highly conserved residue. In vitro functional expression studies showed that the mutations increased the half-life of DNAJB6, extended this effect to the wildtype protein, and reduced the protective antiaggregation effect of DNAJB6. The mutations showed a dominant toxic effect mediated specifically by the cytoplasmic isoform of DNAJB6. The compromised antiaggregation function may lead to impaired protein quality control and accumulation of other proteins. DNAJB6 was found to interact with members of the chaperone-assisted selective autophagy (CASA) complex, including a myofibrillar myopathy (MFM6; <a href="/entry/612954">612954</a>)-related protein BAG3 (<a href="/entry/603883">603883</a>).

None had cardiac, pulmonary, or bulbar involvement. The disorder was slowly progressive, but a wheelchair was required after about 20 years.

<span class="mim-text-font">
<p>DNAJB6 belongs to the evolutionarily conserved DNAJ/HSP40 family of proteins, which regulate molecular chaperone activity by stimulating ATPase activity. DNAJ proteins may have up to 3 distinct domains: a conserved 70-amino acid J domain, usually at the N terminus; a glycine/phenylalanine (G/F)-rich region; and a cysteine-rich domain (Ohtsuka and Hata, 2000). </p>

<strong>Cloning and Expression</strong>

</div>
<span class="mim-text-font">
<p>By database searching for DNAJ-like proteins, Seki et al. (1999) identified and subsequently cloned DNAJB6, which they called MRJ, from a human fetal brain cDNA library. The deduced 241-amino acid protein has a calculated molecular mass of 37 kD. DNAJB6 contains an N-terminal J domain followed by a glycine-rich region, but does not contain a cysteine-rich region. The protein shares 94% sequence identity with the mouse homolog. RT-PCR analysis detected ubiquitous expression of DNAJB6. </p><p>By searching EST databases for J domain-containing proteins, Ohtsuka and Hata (2000) identified 10 mouse and human DNAJ homologs, including mouse DnajB6. The predicted type II transmembrane protein contains 242 amino acids. </p><p>By Northern blot analysis, Chuang et al. (2002) found that the expression of human DNAJB6 was highest in brain and much weaker in all other tissues examined. Within brain, expression was highest in hippocampus and thalamus, and lower in amygdala, substantia nigra, corpus callosum, and caudate nucleus. </p><p>Sarparanta et al. (2012) found expression of the DNAJB6 gene at Z discs in human skeletal muscle. </p><p>DNAJB6 is expressed as 2 isoforms with distinct cellular localizations: DNAJB6a (326 residues) localizes to the nucleus, whereas DNAJB6b (242 residues) localizes to both the nucleus and the cytoplasm. Bengoechea et al. (2015) found expression of both isoforms in human and mouse skeletal muscle. In mouse muscle, Dnajb6a showed nuclear localization and Dnajb6b was incorporated into the sarcomere. </p>

<strong>Gene Function</strong>
</span>
</h4>
</div>
<span class="mim-text-font">
<p>Chuang et al. (2002) demonstrated that full-length DNAJB6 stimulated ATP hydrolysis by HSP70 (see HSPA1A, 140550) in a time- and concentration-dependent manner. Both an N-terminal fragment (amino acids 1-109) and a C-terminal fragment (amino acids 108-241) enhanced the ATPase activity of HSP70. Human embryonic kidney 293 cells transfected with mutant huntingtin (HTT; 613004) N terminus exhibited puncta or aggregates of mutant huntingtin distributed throughout the cytoplasm and nucleus. Coexpression of DNAJB6 delayed aggregate formation and significantly reduced caspase-3 (CASP3; 600636) activation induced by mutant huntingtin. DNAJB6 also inhibited CASP3 activity augmented by the apoptotic reagent staurosporine. </p>

<p>In affected members of a Caucasian family with autosomal dominant limb-girdle muscular dystrophy (LGMDD1; 603511), earlier designated LGMD1E, Harms et al. (2012) identified a heterozygous mutation in the DNAJB6 gene (F93L; 611332.0001). The mutation was identified by whole-genome exome capture followed by next-generation sequencing. Sequencing of the DNAJB6 gene in 13 additional probands with a similar disorder revealed a second mutation (P96R; 611332.0002) in affected members of an African American family with an autosomal dominant myopathy. Both families had adult-onset of slowly progressive muscle weakness resulting in loss of ambulation after about 20 years, although 1 family had greater involvement of the proximal muscles and the other had greater involvement of the distal muscles. Neither family had cardiac or pulmonary involvement. </p><p>Sarparanta et al. (2012) identified 4 different heterozygous mutations in the DNAJB6 gene (611332.0001, 611332.0003-611332.0005) in affected members of 9 families with LGMD1E. Five of the families were of Finnish origin (Sandell et al., 2010 and Hackman et al., 2011) and carried the same mutation (611332.0003). Two additional families had previously been reported by Speer et al. (1995, 1999). Electron microscopy of patient muscle showed Z disc myofibrillar disintegration and autophagic rimmed vacuoles. DNAJB6 was detected in protein accumulations together with its known ligands MLF1 (601402) and HSPA8 (600816). However, DNAJB6 appeared more in the periphery of the protein accumulations, in contrast to more pronounced colocalization seen in myotilinopathies. Three of the mutations resulted in a phe93-to-leu (F93L) substitution at a highly conserved residue. In vitro functional expression studies showed that the mutations increased the half-life of DNAJB6, extended this effect to the wildtype protein, and reduced the protective antiaggregation effect of DNAJB6. The mutations showed a dominant toxic effect mediated specifically by the cytoplasmic isoform of DNAJB6. The compromised antiaggregation function may lead to impaired protein quality control and accumulation of other proteins. DNAJB6 was found to interact with members of the chaperone-assisted selective autophagy (CASA) complex, including a myofibrillar myopathy (MFM6; 612954)-related protein BAG3 (603883). The findings indicated that LGMD1E is mediated by defective chaperone function, resulting in insufficient maintenance of sarcomeric structures or defective clearance of misfolded sarcomeric proteins. </p><p>Stein et al. (2014) noted that all known LGMD1E mutations localized in the conserved G/F domain of DNAJB6. Using yeast-human chimeric proteins, they found that these DNAJB6 mutants were variably deficient in resolving prion protein aggregates in yeast, with strongest effect shown by the F89I mutation (611332.0005) or deletion of the entire G/F domain. TDP43 (TARDBP; 605078) has a domain similar to that found in yeast prion proteins; in addition, TDP43 aggregates into stress granules during heat shock and accumulates in LGMD1E patient muscle. Stein et al. (2014) showed that HeLa cells expressing TDP43 formed nuclear stress bodies during heat shock, and that wildtype, but not G/F mutant, DNAJB6 resolved these stress bodies following recovery from heat shock. LGMD1E patient fibroblasts with the F93L substitution (see 611332.0001) also showed delayed dissolution of TDP43 nuclear stress bodies following recovery from heat shock. </p><p>In affected members of a large family with LGMD1E, Ruggieri et al. (2015) identified a heterozygous missense mutation in the DNAJB6 gene (F100V; 611332.0006). The mutation, which was found by a combination of linkage analysis and exome sequencing, segregated with the disorder in the family. Direct Sanger sequencing of the DNAJB6 gene in 63 patients with sporadic occurrence of a similar disorder identified 4 with de novo heterozygous mutations (611332.0003; 611332.0007-611332.0009), thus accounting for 6.4% of the cohort. All the mutations affected the conserved G/F domain, although direct functional studies were not performed. There was some evidence for a genotype/phenotype correlation: proximal G/F mutations were associated with proximal myopathy, whereas distal G/F mutations were associated with distal-onset myopathy. The mutations were predicted to affect the G/F-J interaction in different ways. </p><p>By exome sequencing in a Hungarian family with a late-onset, mild, and slowly progressive form of LGMDD1, Zima et al. (2020) identified a heterozygous missense mutation in the DNAJB6 gene (F91V; 611332.0010). The authors noted that previous mutations involving the phe91 residue (611332.0007 and 611332.0008) were associated with a more severe form of the disease. </p>

<span class="mim-text-font">
<p>In zebrafish, Sarparanta et al. (2012) found expression of the Dnajb6 gene as early as the embryonic 5-somite stage. Injection of 2-cell embryos with a splice-blocking morpholino resulted in a reproducible muscle fiber detachment phenotype. Detachment of slow fibers from their insertion sites at the vertical myoseptum was evident as early as 2 days after fertilization, suggesting adhesion failure with mechanical load. These data indicated that loss of Dnajb6 leads to defects in muscle integrity. Injection of the human mutants F93L (see, e.g., 611332.0001) or F89I (611332.0005) also caused the muscular phenotype, and coinjection with wildtype Dnajb6 showed enhanced severity of the phenotype, consistent with a dominant-negative effect. </p><p>Bengoechea et al. (2015) found that transgenic mice expressing the LGMD1E-associated DNAJB6 F93L mutation (611332.0001) in the Dnajb6b isoform had early lethality due to profound muscle weakness, whereas mice with the mutation in the Dnajb6a isoform were unaffected after 1 year. Muscle biopsy of affected mice showed localization of mutant Dnajb6b in the Z-disc, myofibrillar disorganization, desmin and keratin inclusions, and abnormal sarcoplasmic protein aggregations of RNA-binding proteins. </p>

The mutation was not found in over 3,000 controls. Five affected individuals had onset of limb-girdle weakness beginning in the fourth decade.

None had cardiac, pulmonary, or bulbar involvement. The disorder was slowly progressive, but a wheelchair was required after about 20 years. Skeletal muscle biopsy from 3 patients showed a chronic myopathy with rimmed vacuoles, variation in fiber size, and internal nuclei. Immunostaining showed TDP43 (605078)- and DNAJB6-positive accumulation in multiple fibers; some inclusions were around and within the vacuoles. Serum creatine kinase was increased, and EMG showed clear myopathic changes. </p><p>Sarparanta et al.

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.
