Cernunno, Nhej1, Non homologous end joining factor 1, Protein cernunnos, XLF, XRCC4 like factor,,NHEJ1
DNA repair protein involved in DNA non-homologous end joining (NHEJ), required for double-strand break (DSB) repair and V(D)J recombination.Plays a key role in NHEJ by promoting the ligation of various mismatched and non-cohesive ends.Together with PAXX, collaborates with DNA polymerase lambda (POLL) to promote joining of non-cohesive DNA ends.
