Annexin A1 (ANXA1)

Links to databases


Annexin A1 belongs to a family of calcium-dependent phospholipid-binding proteins,and has roles in membrane fusion and exocytosis. It is principally located on the cytosolic face of the plasma membrane and exhibits phospholipase A2 inhibitory activity. The protein also plays a key role in the anti-inflammatory effects of glucocorticoid hormones, which increase ANXA1 synthesis. Annexin A1 has also generated interest as a potential target for cancer therapy due to its inhibition of the NF-?B signal pathway, which may otherwise protect tumor cells from apoptosis. ANXA1 has also been reported as a useful diagnostic protein marker for hairy cell leukemia, and as a potential tumor supressor in breast cancer.
