  • FunctionPlays a role in the process of neurogenesis. Required throughout embryonic neurogenesis to maintain neural progenitor cells, also called radial glial cells (RGCs), by allowing their daughter cells to choose progenitor over neuronal cell fate. Not required for the proliferation of neural progenitor cells before the onset of neurogenesis. Also involved postnatally in the subventricular zone (SVZ) neurogenesis by regulating SVZ neuroblasts survival and ependymal wall integrity. May also mediate local repair of brain ventricular wall damage.
  • Sequence similaritiesContains 1 PID domain.
  • Post-translational
    Isoform 1 and isoform 2 are ubiquitinated by LNX leading to their subsequent proteasomal degradation (By similarity). Ubiquitinated; mediated by SIAH1 and leading to its subsequent proteasomal degradation.

Thank you for contacting Abcam.
Unfortunately the exact epitope sight for ab123891 has not been mapped however based on the IF protocol that was used to test the antibody, we believe that the epitope may be intracellular (as they had to use 0.1% T...
