Protein Structure

UniProt Annotation

Function

Plays an important role in spindle pole orientation. Interacts and contributes to the functional activity of G(i) alpha proteins. Acts to stabilize the apical complex during neuroblast divisions. {ECO:0000269PubMed:15632202}.

Subcellular Localization

Cytoplasm {ECO:0000269PubMed:15632202}. Cytoplasm, cell cortex {ECO:0000269PubMed:15632202}. Note=Localizes in the cytoplasm in the interphase and at cell periphery in the metaphase.

Disease Associations

Chudley-McCullough syndrome (CMCS) [MIM:604213]: An autosomal recessive neurologic disorder characterized by early- onset sensorineural deafness and specific brain anomalies on MRI, including hypoplasia of the corpus callosum, enlarged cysterna magna with mild focal cerebellar dysplasia, and nodular heterotopia. Some patients have hydrocephalus. Psychomotor development is normal. {ECO:0000269PubMed:20602914, ECO:0000269PubMed:22578326}. Note=The disease is caused by mutations affecting the gene represented in this entry.

Tissue Specificity
