Data Sheet

Background: C5a receptor (C5a anaphylatoxin chemotactic receptor, or CD88 antigen, C5R1) is a receptor for chemotactic and inflammatory peptide anaphylatoxin C5a. C5a is a classic, potent inflammatory mediator, and the C5R1 receptor stimulates chemotaxis, granule enzyme release and superoxide anion production. C5a receptor antagonists, such as AcPhe[Orn-Pro-D-cyclohexylalanine-Trp-Arg], show therapeutic effects in various inflammatory disease models. C5a receptor may also be involved in neurodegeneration and Alzheimer’s disease.

Application: Functional assays
