Annexin A1 (ANXA1) Mouse Recombinant Protein

ANXA1: a calcium/phospholipid-binding protein with which promotes membrane fusion and is involved in endocytosis. Has anti-inflammatory properties and inhibits phospholipase A2 activity. Accumulates on internalized vesicles after EGF-stimulated endocytosis, suggesting that it may be required for a late stage in inward vesiculation. Phosphorylated by PKC, EGFR and Chak1. Phosphorylation results in loss of the inhibitory activity. Annexins are a family of structurally related proteins whose common property is calcium-dependent binding to phospholipids. There are at least ten different annexins in mammalian species. Annexins do not contain signal peptides, yet some annexins (A1, A2 and A5) appear to be secreted in a physiologically regulated fashion.
