  • Function

    Reversible hydration of carbon dioxide. Participates in pH regulation. May be involved in the control of cell proliferation and transformation. Appears to be a novel specific biomarker for a cervical neoplasia.
  • Tissue specificity

    Expressed primarily in carcinoma cells lines. Expression is restricted to very few normal tissues and the most abundant expression is found in the epithelial cells of gastric mucosa.
  • Sequence similarities

    Belongs to the alpha-carbonic anhydrase family.
    Contains 1 alpha-carbonic anhydrase domain.
  • Post-translational

    Asn-346 bears high-mannose type glycan structures.
  • Cellular localization

    Nucleus. Nucleus, nucleolus. Cell membrane. Cell projection, microvillus membrane. Found on the surface microvilli and in the nucleus, particularly in nucleolus.
