Background: Complement Component C3aR

Complement Component 3a receptor (C3a R) is an ~90 kDa G-protein coupled 7-transmembrane sulfated glycoprotein expressed on myeloid peripheral blood leukocytes, and on activated lymphocytes, endothelial and internal organ epithelial cells. Engagement of C3a R by C3a activates mast cells and neutrophils, triggering degranulation in airways during asthmatic allergen challenges. It assists in Th2-type inflammatory reactions and stimulates leukocyte chemotaxis. Human C3a R extracellular regions share 50% and 42% amino acid identity with mouse and rat C3a R, respectively.
