annexin

annexin
an·nex·in (ə-nekґsin) any of a family of Ca2+-dependent phospholipid-binding proteins, which share a common primary structure in the C-terminal region, four or eight repeats of an approximately 70 amino acid sequence. Proposed functions include roles in mediation of intracellular calcium signals, aggregation of membranes and vesicles, and ion channel formation. Some inhibit activation of phospholipase A2, thus also inhibiting synthesis of prostaglandins and other arachidonic acid derivatives.
