Funkcija

uredi

Ovaj gen kodira člana porodice bazni heliks-petlja-heliks leucinskih zatvarača i može funkcionirati kao ćelijski transkripcijski faktor. Kodirani protein može aktivirati transkripciju preko inicijatorskog (Inr) elementa i E-kutijskog motiva bogatih pirimidinom. Ovaj gen je povezan sa porodičnom kombinovanom hiperlipidemijom (FCHL). Za ovaj gen identificirane su dvije varijante transkripta koje kodiraju različite izoforme su.[6]

Studija na miševima je pokazala da smanjeni nivoi USF1 povećavaju metabolizam smeđe masti.[8]

Interakcije

uredi

Pokazano je da USF1 (ljudski gen) ima interakscije sa USF2,[9][10] FOSL1,[11] I GTF2I.[12][13]
