Recombinant Human Annexin A1/ANXA1 Protein (RPES2602)



ELISA Kit Technical Manual

Recombinant Human Annexin A1/ANXA1 Protein

Background:Annexin A1 is the first characterized member of the annexin family of proteins and is able to bind to cellular membranes in a calcium-dependent manner, promoting membrane fusion and endocytosis. Annexin A1 has anti-inflammatory properties and inhibits phospholipase A2 activity. Annexin A1 also has roles in many diverse cellular functions, such as membrane aggregation, inflammation, phagocytosis, proliferation, apoptosis, and tumorigenesis and cancer development. ANXA1 is strongly expressed on the cell membrane and occasionally in the cytoplasm of tumor cells in 97% of samples from patients with hairy cell leukemia.

UniProt Protein Function: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.
