NR2F1
COUP-TF1 (COUP transkripcijski faktor 1) znan i kao NR2F1 (od eng. skr. za Nuclear Receptor subfamily 2, član 1) grupe F, jest protein koji je kod ljudi kodiran genom NR2F1 sa hromosoma 5.[1][2] Ovaj protein je član receptoa jedarnih hormona iz porodice receptora steroidnih hormona.

Funkcija[uredi | uredi izvor]
COUP (kokošiji ovalbuminski uzvodni promotor) faktor transkripcije veže se za ovalbuminski promotor i, zajedno sa drugim proteinom (S300-II), stimulira [ početak transkripcije.[4][5] COUP-TF1 veže se za direktna ponavljanja i palindromskom motivu 5'-AGGTCA-3 '.[6]
