MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a member of the GP40 family of G protein-coupled receptors that are clustered together on chromosome 19. The encoded protein is a receptor for short chain free fatty acids and may be involved in the inflammatory response and in regulating lipid plasma levels. [provided by RefSeq, Apr 2009]
PHENOTYPE: Mice homozygous for a null allele show altered granulocyte and neutrophil physiology and increased inflammation in models of induced colitis, arthritis and asthma, whereas homozygotes for a different null allele show reduced neutrophil recruitment and decreased susceptibility to induced colitis.
