FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] C3a is an anaphylatoxin released during activation of the complement system. The protein encoded by this gene is an orphan G protein-coupled receptor for C3a. Binding of C3a by the encoded receptor activates chemotaxis, granule enzyme release, superoxide anion production, and bacterial opsonization. [provided by RefSeq, May 2016]
PHENOTYPE: Homozygous targeted mutants display protective effects against the changes in lung physiology after allergen challenge, increased lethality to endotoxin shock, and elevated IL1B following LPS challenge, supporting the role of C3arin proinflammatory responses. [provided by MGI curators]
