XPB (Xeroderma Pigmentosum B) je ATP zavisna ljudska DNK helikaza koja je deo kompleksa TFIIH transkripcionog faktora. 3D struktura XPB homologa je kristalografski.[1]

Funkcija[uredi | uredi kod]

XPB učestvuje u normalnoj bazalnoj transkripciji, transkripciono spregnutoj popravci (TCR), i popravci isecanjem nukleotida (NER). Pokazano jed a prečišćeni XPB razvija DNK u 3’-5’ pravcu.

Interakcije[uredi | uredi kod]

XPB formira interakcije sa XPC,[2] BCR genom,[3] ERCC2,[4][5][6][7] P53,[8] GTF2H2,[4][5] GTF2H1,[4][5][9] GTF2H5,[4] ciklin zavisnom kinazom,[4][9][10] PSMC5[11] i GTF2H4.[4][5]
