ANXA2 a calcium-regulated membrane-binding protein whose affinity for calcium is greatly enhanced by anionic phospholipids. It binds two calcium ions with high affinity. Heterotetramer containing 2 light chains of S100A10 2 heavy chains of ANXA2. May cross-link plasma membrane phospholipids with actin and the cytoskeleton and be involved with exocytosis. Annexins are a family of structurally related proteins whose common property is calcium-dependent binding to phospholipids. There are at least ten different annexins in mammalian species. Annexins do not contain signal peptides, yet some annexins (A1, A2 and A5) appear to be secreted in a physiologically regulated fashion. Note: This description may include information from UniProtKB.
