UDP glukuronoziltransferaza 2 familija, polipeptid B4, takođe poznata kao UGT2B4, je enzim koji je kod ljudi kodiran genom UGT2B4.^[4]^[5]^[6]

Function

UGT2B4 je uglavnom uključen u glukuronidaciju hiodezoksiholne kiseline, žučne kiseline i katehol-estrogena, kao što su 17-epiestriol i 4-hidroksi-estron.^[7]

Izražavanje enzima UGT2B4 pojačava farnezoidni X receptor (FXR), nuklearni receptor koji se aktivira žučnim kiselinama.^[8] Ove iste žučne kiseline su supstrati za enzim UGT2B4. Otuda povećanje regulacije UGT2B4 aktiviranim FXR-om obezbeđuje mehanizam za detekciju, konjugaciju i naknadnu eliminaciju toksičnih žučnih kiselina.
