  • 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.
  • Tissue specificity

    Ubiquitously expressed.
  • Involvement in disease

    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.
  • Sequence similarities

    Belongs to the GPSM family.
    Contains 4 GoLoco domains.
    Contains 8 TPR repeats.
  • Cellular localization

    Cytoplasm. Cytoplasm > cell cortex. Localizes in the cytoplasm in the interphase and at cell periphery in the metaphase.
