Ovaj protein učestvuje u popravci jednolančankih prekida DNK formiranih izlaganjem jonizujućoj radijaciji i alkilujućim agensima. Ovaj protein formira interakcije sa DNK ligazom III, polimerazom beta i poli ADP-riboznom polimerazom da bi učestvovao u putu popravke isecanjem baza. Moguće je da ima ulogu u DNK manipulacijama tokom mejoze i rekombinacije u ćelijama zametka. Retki mikrosatelitni polimorfizam ovog genu je vezan za pojavu pojedinih tipova kancera.[1]
