    basic FUNCTION
  • carbonic anhydrase VIII, putatively involved in nerve function
  • reversibly hydrating Co2 in cellular ion transport and pH homeostasis
  • playing roles in various biological process of the CNS
  • playing a role in the growth of colon cancer cells
  • autoantigen involved in the pathogenesis of melanoma-associated paraneoplastic cerebellar degeneration
  • is selectively expressed within neural circuits, and may be important for modulating retinal neurotransmission
  • specific role of CA8 to protect cells from stresses 3)

    INTERACTION
    DNA

    small molecule metal binding,
  • Zn2+
  • protein
  • ITPR1-binding protein (binding site located within the modulatory domain of ITPR1 amino acids 1387-1647)
  • CA8 is a novel important regulator of Purkinje cell dendritic development and that its expression is controlled by PRKCG activity
  • CA8 is an allosteric inhibitor of ITPR1, which regulates intracellular calcium release fundamental to critical cellular functions including neuronal excitability, neurite outgrowth, neurotransmitter release
  • CA8 is a novel important regulator of Purkinje cell dendritic development and that its expression is controlled by PRKCG activity
  • might facilitate cancer cell invasion via the activation of PTK2-MMP9 signaling
