  • Application notes
    Is unsuitable for IP.
  • Target

    • Function

      Calcium-regulated membrane-binding protein whose affinity for calcium is greatly enhanced by anionic phospholipids. It binds two calcium ions with high affinity. May be involved in heat-stress response.
    • Sequence similarities

      Belongs to the annexin family.
      Contains 4 annexin repeats.
    • Domain

      A pair of annexin repeats may form one binding site for calcium and phospholipid.
    • Post-translational

      Phosphorylation of Tyr-24 enhances heat stress-induced translocation to the cell surface.
    • Cellular localization

      Secreted > extracellular space > extracellular matrix > basement membrane. Melanosome. In the lamina beneath the plasma membrane. Identified by mass spectrometry in melanosome fractions from stage I to stage IV. Translocated from the cytoplasm to the cell surface through a Golgi-independent mechanism.
