Annexin A4 (Annexin IV, ANX4, ANXA4, Lipocortin IV, Placental Anticoagulant Protein II, Zymogen Granule Membrane-Associated Protein 36kD, ZAP36)

Annexin A4 is a 321aa, 36kD member of the Annexin protein family. Annexins are a family of Calcium-dependent phospholipid-binding proteins that are preferentially located on the cytosolic face of the plasma membrane. The Annexin's have a molecular weight of ~35-40kD and consist of a unique amino terminal domain followed by a homologous C-terminal core domain containing the calcium-dependent phospholipid-binding sites. The C terminal domain is comprised of four 60-70aa repeats, known as annexin repeats or an endonexin fold (Annexin A6 contains 8 annexin repeats). The four annexin repeats form a highly alpha-helical, tightly packed disc known as the annexin domain, which binds to phospholipids in the membrane in a calcium-dependent manner. Members of the annexin family play a role in cytoskeletal interactions, phospholipase inhibition, regulation of cellular growth and intracellular signal transduction pathways. Human Annexin A4 shares 92% identity with mouse and rat Annexin A4. \n\nApplications: \nSuitable for use in Western Blot.
