Flap endonukleaza 1 je enzim koji je kod ljudi kodiran FEN1 genom.^[4]^[5]

Protein kodiran ovim genom uklanja 5' prepuste tokom DNK popravke i obrađuje 5' krajeve Okazakijevih fragmenta pri sintezi zaostajućeg lanca DNK. Direktna fizička interakcija između tog proteina i AP endonukleaze 1 tokom popravke isecanjem dugog segmenta baza omogućava koordinirani pristup proteina supstratu, čime se supstrat dodaje od jednog enzima do drugog. Ovaj protein je član XPG/RAD2 familije endonukleaza i jedan je od deset proteina koji su esencijalni za bezćelijsku replikaciju DNK. Sekundarna struktura DNK može da inhibira flap obradu na pojedinim trinukleotidnim ponavljanjima u maniru zavisnom od dužine koji skrivaju 5' kraj prepusta, koji je neophodan za vezivanje i presecanje proteinom kodiranim ovim genom. Stoga sekundarna struktura može da onemogući protektivnu funkciju ovog proteina, što dovodi do trinukleotidnih ekspanzija specifičnih za mesto.^[5]
