Secondary Information

Protein Function Similar to annexin A5; family of Ca2+/lipid-binding proteins; implicated in Ca2+- regulated exocytotic events, endocytosis and stabilization of specific domains of organelle membranes and the plasma membrane; has RNA-binding capacity; participate in cell proliferation, growth, movement, metabolism, apoptosis, and they also play important roles in cytoskeletal organization, exocytosis, endocytosis, invasion, and metastasis;
Biochemical Properties soluble, hydrophilic proteins that bind to negatively charged phospholipids in a Ca2 -dependent manner; highly α-helical and forms a compact, slightly curved disc that has a convex surface harboring the Ca2+- and membrane binding sites and a concave side that points away from the membrane and is thereby available for other types of interaction/regulation; Annexin complexes with EF hand-type Ca2 binding proteins
Significance in milk AnxA2 could be involved in milk synthesis and proliferation of bovine mammary epithelial cells
PTMs Phosphorylated; phosphorylation sites are unique NH2-terminal domains
Site(s) of PTM(s)

N-glycosylation, O-glycosylation,
Significance of PTMs After phosphorylation undergoes proteolytic cleavage which show an altered sensitivity toward Ca2+/phospholipid
