<strong>Cloning and Expression</strong>

</h4>
</div>
<span class="mim-text-font">
<p>Huang et al. (2011) identified 2 TMEM237 splice variants that include either exon 1 or exon 2 and are translated into 2 different protein isoforms. Transcript-1 contains exon 1 and encodes a deduced 408-amino acid protein, designated isoform A, that has a long N-terminal domain, followed by 4 transmembrane domains and a short C-terminal tail. Both the N- and C-terminal domains are intracellular. The N-terminal domain and the intracellular loops between the transmembrane helices contain short repetitive motifs of basic (arg and/or lys) and acidic (asp and/or glu) residues that are highly conserved in metazoans. Immunocytochemical staining of polarized ciliated mouse inner medullary collecting duct (IMCD3) cells revealed that Tmem237 localized to the transition zone at the proximal region of primary cilia. </p><p>Zuniga and Craft (2010) cloned mouse Tmem237, which they called Als2cr4, and identified variants encoding 2 protein isoforms that differ only at the extreme N terminus. The deduced 403-amino acid protein encoded by Als2cr4 transcript-2 has a calculated molecular mass of about 45 kD and shares 81% and 82% identity with isoforms A and B of human ALS2CR4, respectively. Mouse Als2cr4 has a long N-terminal domain containing a tetratricopeptide motif, followed by 4 transmembrane segments and a short C-terminal tail. Zuniga and Craft (2010) noted that previous in situ hybridization and gene expression profiles revealed high Als2cr4 expression in eye, hippocampus, cerebellum, and olfactory bulb. By immunohistochemical analysis of retina, Zuniga and Craft (2010) found Als2cr4 enriched in retina and localized to photoreceptor outer segments, ciliary complex, and horizontal cells in the outer plexiform layer. Immunoelectron microscopy verified Als2cr4 expression in the discs of photoreceptor outer segments. </p>

<strong>Gene Function</strong>
</span>
</h4>
</div>
<span class="mim-text-font">
<p>By yeast 2-hybrid analysis of mouse retina, Zuniga and Craft (2010) found that Als2cr4 interacted with Arr4 (ARR3; 301770). Immunoprecipitation analysis of light-adapted mouse retinas showed that Als2cr4 associated with cytoskeletal components. Als2cr4 interacted directly with myosin Va (MYO5A; 160777), myosin VI (MYO6; 600970), and Arr3. </p><p>Huang et al. (2011) found that knockdown of Tmem237 in IMCD3 cells via small interfering RNA impaired ciliogenesis and caused mislocalization of RhoA (165390) to peripheral regions of the basal body and to basolateral cell-cell contacts. Similarly, fibroblasts from a patient with Joubert syndrome-14 (JBTS14; 614424) and a null mutation in TMEM237 (R18X; 614423.0001) showed deregulation of canonical and noncanonical Wnt signaling and mislocalization of RHOA. Morpholino-mediated knockdown of Tmem237 in zebrafish caused gastrulation defects consistent with ciliary dysfunction that were similar to defects resulting from knockdown of other transition zone proteins, including Mks3 (TMEM67; 609884) and Tmem216 (613277). These defects in zebrafish were partially reversed by expression of human TMEM237, MKS3, or TMEM216. In both IMCD3 cells and C. elegans, transition zone localization of Tmem237 was dependent upon other transition zone proteins. Huang et al. (2011) hypothesized that TMEM237, TMEM216, and MKS3 function as a module to regulate ciliogenesis and WNT signaling. </p>

<p>By homozygosity mapping followed by candidate gene analysis in 10 related Canadian Hutterite families with Joubert syndrome-14 (JBTS14; 614424), Huang et al. (2011) identified a homozygous truncating mutation in the TMEM237 gene (R18X; 614423.0001). Homozygous or compound heterozygous mutations were also found in 3 additional families with the disorder (614423.0002-614423.0005). All the mutations were predicted to result in a null allele. Protein extracts from patient cells showed perturbation of the noncanonical WNT pathway, with constitutive phosphorylation and hyperactivation of DVL1 (601365) and an increase in CTNNB1 (116806) levels. There was also an increase in RHOA signaling. The phenotype was characterized by severe mental retardation, abnormal breathing pattern in infancy, molar tooth sign on brain imaging, renal cysts, abnormal eye movements, and early death in many patients. </p>

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
