Funkcija uredi

Ovaj gen kodira protein ponovljenog WD-a, koji stupa u interakciju s Cockayneovim sindromom tipa B (CSB) i p44 proteinima, a potonji je podjedinica RNK-polimeraze II transkripcijskog faktora II H . Mutacije u ovom genu identificirane su kod pacijenata s nasljednom bolešću Cockayneov sindrom (CS). CS je poremećaj ubrzanog starenja koji karakterizira fotoosjetljivost, poremećen razvoj i višesistemska progresivna degeneracija. CS ćelije su abnormalno osjetljive na ultraljubičasto zračenje i neispravne su u popravljanju transkripcijski aktivnih gena. Alternativno je za ovaj gen pronađeno više prerađenih varijanti transkripta koje kodiraju različite izoforme.^[6]

Smatra se da proteini CSA i CSB funkcioniraju u transkripciji i popravkama DNK, ponajviše u popravljanju ekscizije (isijecanja) nukleotida povezanih s transkripcijom. Ćelije s nedostatkom CSA i CSB pokazuju nedostatak preferencijalne popravke UV-induciranih ciklobutanskih pirimidinskih dimera u aktivno transkribiranim genima, u skladu s neuspjelim odgovorom popravljanja ekscizije vezanih nukleotida pri transkripciji.^[8] Unutar ćelije, CSA protein nalazi se na mjestima oštećenja DNK, posebno međulančanim unakrsnim vezama, dvolančanim prekidima i nekim monoadodacima.^[9]

CS nastaje zbog mutacija zametne linije u bilo kojem od dva gena, CSA (ERCC8) ili CSB (ERCC6) . Mutacije CSA općenito uzrokuju umjereniji oblik CS-a od mutacija CSB.^[9] Mutacije u genu CSA čine oko 20% slučajeva CS-a.^[10]

Interakcije uredi

Za ERCC8 pokazano je daima interakcije sa XAB2.^[11]
