[https://www.uniprot.org/uniprot/ANXA1_PIG ANXA1_PIG] Calcium/phospholipid-binding protein which promotes membrane fusion and is involved in exocytosis. This protein regulates phospholipase A2 activity. It seems to bind from two to four calcium ions with high affinity.

== Publication Abstract from PubMed ==
 +
Annexins comprise a multigene family of Ca2+ and phospholipid- binding proteins. They consist of a conserved C-terminal or core domain that confers Ca2+-dependent phospholipid binding and an N-terminal domain that is variable in sequence and length and responsible for the specific properties of each annexin. Crystal structures of various annexin core domains have revealed a high degree of similarity. From these and other studies it is evident that the core domain harbors the calcium-binding sites that interact with the phospholipid headgroups. However, no structure has been reported of an annexin with a complete N-terminal domain. We have now solved the crystal structure of such a full-length annexin, annexin 1. Annexin 1 is active in membrane aggregation and its refined 1.8 A structure shows an alpha-helical N-terminal domain connected to the core domain by a flexible linker. It is surprising that the two alpha-helices present in the N-terminal domain of 41 residues interact intimately with the core domain, with the amphipathic helix 2-12 of the N-terminal domain replacing helix D of repeat III of the core. In turn, helix D is unwound into a flap now partially covering the N-terminal helix. Implications for membrane aggregation will be discussed and a model of aggregation based on the structure will be presented.
