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.
Defects in GPSM2 are the cause of deafness autosomal recessive type 82 (DFNB82) [MIM:613557]. DFNB82 is a form of non-syndromic deafness characterized by prelingual, bilateral, severe, sensorineural hearing loss. There are no symptoms of vestibular dysfunction.
Belongs to the GPSM family. Contains 4 GoLoco domains. Contains 8 TPR repeats.
Cytoplasm. Cytoplasm > cell cortex. Localizes in the cytoplasm in the interphase and at cell periphery in the metaphase.
Detection of GPSM2 by Western Blot of Immunprecipitate.
ab109594 at 1µg/ml staining GPSM2 in HeLa whole cell lysate immunoprecipitated using ab109594 at 6µg/mg lysate (1 mg/IP; 20% of IP loaded/lane).
Detection: Chemiluminescence with exposure time of 30 seconds.
