Funkcija

uredi

Protein kodiran ovim genom je član porodice helikaza RecQ DEAH i stupa u interakciju sa BRCT ponavljanjima raka dojke tipa 1 (BRCA1). Vezani kompleks je važan u normalnoj funkciji popravljanja prekida dvostrukog lanca raka dojke tipa 1 (BRCA1). Ovaj gen može biti meta mutacija koje izazivaju rak zametne linije.[7]

Čini se da je ovaj protein važan i kod raka jajnika, gdje djeluje kao supresor tumora.[8] Mutacije u BRIP1 povezane su sa 10-15% rizikom od raka jajnika.[9]

Čini se da BRIP1 ima važnu ulogu u neuronskim ćelijama, tako što potiskuje oksidativni stres, a ekscitotoksičnost inducira oštećenje DNK i štiti integritet mitohondrija.[10] Nedostatak BRIP1 uzrokuje povećano oštećenje DNK, mitohondrijske abnormalnosti i smrt neuronske ćelije.

BRIP1 protein je DNK helikaza koja se koristi u homolognorekombinacijskoj popravci i u odgovoru ćelije na stres replikacije DNK.[11] Djelimično, BRIP1 obavlja svoju funkciju interakcijom s drugim ključnim proteinima za popravku DNK, posebno MLH1, BRCA1 i BLM.[11] Ova grupa proteina pomaže u osiguravanju stabilnosti genoma, a posebno popravlja prekide dvostrukih lanaca DNK tokom profaze 1 mejoze.
