annexin a2


Summary: A member of the annexin family that is a substrate for a tyrosine kinase, ONCOGENE PROTEIN PP60(V-SRC). Annexin A2 occurs as a 36-KDa monomer and in a 90-KDa complex containing two subunits of annexin A2 and two subunits of S100 FAMILY PROTEIN P11. The monomeric form of annexin A2 was formerly referred to as calpactin I heavy chain.
