Disease

[GPSM2_HUMAN] Autosomal recessive nonsyndromic sensorineural deafness type DFNB;Chudley-McCullough syndrome. 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. Note=The disease is caused by mutations affecting the gene represented in this entry.[1] [2]

Function

[GPSM2_HUMAN] 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.[3] [INSC_HUMAN] May function as an adapter linking the Par3 complex to the GPSM1/GPSM2 complex. Involved in spindle orientation during mitosis it may regulate cell proliferation and differentiation in the developing nervous system. May play a role in the asymmetric division of fibroblasts and participate in the process of stratification of the squamous epithelium.[4]
