MGI Phenotype FUNCTION: This gene encodes a multi-pass membrane protein that functions as a G-protein coupled receptor. The encoded protein binds thromboxane A2, resulting in the aggregation of platelets and constriction of blood vessels. Alternative splicing results in multiple transcript variants for this gene. [provided by RefSeq, Mar 2013]
PHENOTYPE: Homozygotes for a null allele show prolonged bleeding, and altered platelet aggregation and vascular responses to TXA2, arachidonic acid and injury. Homozygotes for another null allele show splenomegaly, reduced DC-T cell adhesion, enhanced contact hypersensitivity, and cervical lymphadenopathy. [provided by MGI curators]
