Receptor žučne kiseline je G-protein spregnuti receptor koji vezuje žučne kiseline.[1] Jedan od efekata ovog receptora je aktivacija enzima dejodinaza, koji konvertuje prohormon tiroksin (T4) u aktivni hormon trijodotironin (T3). T3 zatim aktivira receptor tiroidnog hormona koji uvećava metaboličku stopu.[2][3]
Ovaj gen kodira protein koji je član familije G protein-spregnutih receptora. On dejstvuje kao receptor na ćelijskoj površini za žučnu kiselinu. Izlaganje ćelija koje izražavaju ovaj GPCR žučnoj kiselini uzrokuje produkciju intraćelijskog cAMP, aktivaciju signalnog puta MAP kinaza, i internalizaciju receptora. Za ovaj receptor se smatra da učestvuje u supresiji funkcija makrofaga i regulacije energije homeostaze žučnim kiselinama. Alternativno splajsovanje stvara transkriptne varijante koje kodiraju isti protein.[4]
