  • FunctionCalcium-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 similaritiesBelongs to the annexin family.
    Contains 4 annexin repeats.
  • DomainA 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 localizationSecreted > 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.
