C5AR1 Antibody – Rat Monoclonal

C5aR: a family 1 G-protein coupled receptor that stimulates the GTPase activity of Gi2. Receptor for the chemotactic and inflammatory complement factor C5a. Stimulates chemotaxis, granule enzyme release and superoxide anion production. Phosphorylated in response to C5a or after stimulation of cells with phorbol esters. Expressed on monocytes, granulocytes, dendritic cells, astrocytes and microglia.
