GeneCards Summary for C5AR1 Gene
C5AR1 (Complement C5a Receptor 1) is a Protein Coding gene. Diseases associated with C5AR1 include Hypersensitivity Reaction Type Iii Disease and Mast-Cell Sarcoma. Among its related pathways are Complement and coagulation cascades and Signaling by GPCR. Gene Ontology (GO) annotations related to this gene include G protein-coupled receptor activity and complement component C5a binding. An important paralog of this gene is C3AR1.
UniProtKB/Swiss-Prot Summary for C5AR1 Gene
Receptor for the chemotactic and inflammatory peptide anaphylatoxin C5a (PubMed:1847994, PubMed:8182049, PubMed:7622471, PubMed:9553099, PubMed:10636859, PubMed:15153520, PubMed:29300009). The ligand interacts with at least two sites on the receptor: a high-affinity site on the extracellular N-terminus, and a second site in the transmembrane region which activates downstream signaling events (PubMed:8182049, PubMed:7622471, PubMed:9553099). Receptor activation stimulates chemotaxis, granule enzyme release, intracellular calcium release and superoxide anion production (PubMed:10636859, PubMed:15153520).
The complement system is a biochemical pathway involved in both innate and adaptive immune responses. There are four main functions of the complement system; lysis of microorganisms, promotion of phagocytosis, triggering inflammation and immune clearance.
