This antibody gave a positive signal in the following whole cell lysates: HeLa (Human epithelial carcinoma cell line), HEK293 (Human embryonic kidney cell line), HepG2 (Human hepatocellular liver carcinoma cell line).
Storage instructionsShipped at 4°C. Store at +4°C short term (1-2 weeks). Upon delivery aliquot. Store at -20°C or -80°C. Avoid freeze / thaw cycle.
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 modificationsPhosphorylation of Tyr-24 enhances heat stress-induced translocation to the cell surface. ISGylated.
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.
