Funkcija

uredi

Ovaj gen kodira jednu od šest podjedinica kolagena tipa IV, glavne strukturne komponente baznih membrana. Ova konkretna podjedinica kolagena IV, međutim, nalazi se samo u podskupu baznih membrana. Poput ostalih članova porodice kolagenskih gena tipa IV, ovaj gen je organiziran u konformaciji glava do glave s drugim genom za kolagen tipa IV, tako da svaki par gena dijeli zajednički promotor. Mutacije ovog gena su povezane sa autosomno recesivnim tipom II Alportovog sindroma (nasljedna glomerulonefropatija) i sa porodičnom benignom hematurijom (bolest tanke bazne membrane). Za ovaj gen su identificirana dvije varijante transkripta, koje se razlikuju samo po mjestima početka transkripcije, i, kao što je uobičajeno za gene kolagena, višestruka poliadenilacija nalazi se u 3' UTR-regiji.[6]
