Title: Annexins
Literature References: Family of calcium and phopholipid binding proteins; virtually ubiquitous in both animal and plant cells. Characterized by a common structure composed of 4 or 8 homologous repeats of ~70 amino acids. Involved in membrane trafficking, transmembrane channel activity, inhibition of phospholipase A2, and inhibition of coagulation. Known variously by such names as synexin, lipocortin, anchorin, and calpactin, the term annexins was chosen for their ability to bind, or "annex", to cellular membranes.
