ARNT (skr. punog naziva na engleskom: jedarni translokator receptora aril-ugljovodonika) jest gen koji se kod ljudi nalazi na hromosomu 1. Kodira jedarni translokator receptora aril ugljovodonika, protein koji formira kompleks sa za ligand vezanim aril ugljikovodični receptor (AhR), a potreban je za funkciju receptora.

Aminokiselinska sekvenca

Funkcija

[uredi | uredi izvor]

Kodirani protein je takođe identifikovan kao beta podjedinica heterodimernog transkripcijskog faktora, hipoksija-inducibilni faktor 1 (HIF1). Translokacija t(1;12)(q21;p13), koja rezultira fuzijom proteina TEL-ARNT, povezana je sa akutnom mijeloblastnom leukemijom. Za ovaj gen su opisane tri alternativno prerađene varijante transkripta koje kodiraju različite izoforme.

Aril-hidrokarbonski receptor (AhR) uključen je u indukciju nekoliko enzima koji učestvuju u ksenobiotskom metabolizmu. Citosolni oblik aril-ugljokovodikovog receptora bez liganda složen je u protein toplotnog šoka 90. Vezivanje liganda, koji uključuje dioksin i policiklični aromatski ugljikovodik, rezultira translokacijom podjedinice koja vezuje ligand samo u[6] jedru. Indukcija enzima uključenih u metabolizam ksenobiotika događa se vezivanjem AhR vezanog za ligand elemenata koji reaguju na ksenobiotike u promotorima gena za ove enzime.
