Annexin A2 also known as annexin II is a protein that in humans is encoded by the ANXA2 gene.[1]

Annexin 2 is involved in diverse cellular processes such as cell motility (especially that of the epithelial cells), linkage of membrane-associated protein complexes to the actin cytoskeleton, endocytosis, fibrinolysis, ion channel formation, and cell matrix interactions. It is a calcium-dependent phospholipid-binding protein whose function is to help organize exocytosis of intracellular proteins to the extracellular domain. Annexin II is a pleiotropic protein meaning that its function is dependent on place and time in the body.


The ANXA2 gene, located at 15q22.2, has three pseudogenes located on chromosomes 4, 9 and 10, respectively. Multiple alternatively spliced transcript variants encoding different isoforms have been found for this gene.[2]


This protein is a member of the annexin family. Members of this calcium-dependent phospholipid-binding protein family play a role in the regulation of cellular growth and in signal transduction pathways. This protein functions as an autocrine factor which heightens osteoclast formation and bone resorption.[2]

Annexin A2 has been proposed to function inside the cell in sorting of endosomes and outside the cell in anticoagulant reactions.


Annexin A2 has been shown to interact with Prohibitin,[3] CEACAM1,[4] S100A10,[5][6] PCNA[7] and complement Factor H [8]
