The annexin superfamily consists of 13 calcium or calcium and phospholipid binding proteins with high biological and structural homology. Annexin-1 (ANXA1) is the frst characterized member of the annexin family of proteins able to bind to cellular membranes in a calcium-dependent manner which promotes membrane fusion and is involved in endocytosis. Annexin A1 has anti-infammatory properties and inhibits phospholipase A2 activity. Annexin A1 can accumulate on internalized vesicles after EGF-stimulated endocytosis,suggesting that it may be required for a late stage in inward vesiculation.Phosphorylation by PKC, EGFR and Chak1 results in inhibition of annexin A1 function. Annexin A1 has also been identifed as one of the 'eat-me' signals on apoptotic cells to be recognised and ingested by phagocytes. Annexin A1, as an endogenous anti-infammatory mediator, has roles in many diverse cellular functions, such as membrane aggregation, infammation, phagocytosis,proliferation, apoptosis, and tumorigenesis and cancer development.
