TEF (gen)
Tirotrofni embrionski faktor jest protein koji je kod ljudi kodiran genom TEF sa hromosoma 22.[5][6][7]
Aminokiselinska sekvenca
urediDužina polipeptidnog lanca je 303 aminokiseline, a molekulska težina 33.248 Da.[7]

Funkcija
urediTirotrofni embrionskii faktor (TEF), faktor transkripcije, je član potporodikce PAR (aminokiselina bogatih prolinom), transkripcijskih faktora bazne regije/leucinskog zatvarača (bZIP). Kod odraslih životinja, eksprimira se u širokom spektru ćelija i tkiva, ali tokom razvoja ebembriona, izgleda da je ekspresija TEF-a ograničena na razvoj prednjeg režnja hipofiza, što se podudara sa pojavom tiroid-stimulirajućieg hormona beta (TSHB). TEF se može vezati i transaktivirati za TSHB promotor.
Pokazuje homologiju (u funkcionalnim domenima) sa drugim članovima potporodice transkripcionih faktora PAR-bZIP, koji uključuju albumin D-kutija|D-kutijski]]-vezanog proteina (DBP), ljudski faktor jetrene leukemije (HLF) i kokošiji i vitelogenin gen-vezujući protein (VBP); VBP se smatra kokošijim homologom TEF-a. Različiti članovi potporodice mogu lahko formirati heterodimere i dijeliti svojstva vezanja DNK i regulatora transkripcije.[7]
