FUNCTION: DNA repair protein involved in DNA nonhomologous end joining (NHEJ) required for double-strand break (DSB) repair and V(D)J recombination. May serve as a bridge between XRCC4 and the other NHEJ factors located at DNA ends, or may participate in reconfiguration of the end bound NHEJ factors to allow XRCC4 access to the DNA termini. It may act in concert with XRCC6/XRCC5 (Ku) to stimulate XRCC4-mediated joining of blunt ends and several types of mismatched ends that are noncomplementary or partially complementary.

SUBUNIT: Interacts with XRCC4 and the XRCC4-LIG4 complex. Binds DNA in a length-dependent manner.

INTERACTION: Self; NbExp=1; IntAct=EBI-847807, EBI-847807; P49917:LIG4; NbExp=4; IntAct=EBI-847807, EBI-847896; Q13426:XRCC4; NbExp=3; IntAct=EBI-847807, EBI-717592;

SUBCELLULAR LOCATION: Nucleus.

TISSUE SPECIFICITY: Ubiquitously expressed.

DISEASE: Defects in NHEJ1 are the cause of severe combined immunodeficiency due to NHEJ1 deficiency (NHEJ1-SCID) [MIM:611291]; also known as autosomal recessive T cell-negative, B cell-negative, NK cell-positive, severe combined immunodeficiency with microcephaly, growth retardation and sensitivity to ionizing radiation or NHEJ1 syndrome. SCID refers to a genetically and clinically heterogeneous group of rare congenital disorders characterized by impairment of both humoral and cell-mediated immunity, leukopenia and low or absent antibody levels. Patients with SCID present in infancy with recurrent, persistent infections by opportunistic organisms. The common characteristic of all types of SCID is absence of T-cell-mediated cellular immunity due to a defect in T-cell development. NHEJ1-SCID is characterized by a profound T- and B-lymphocytopenia associated with increased cellular sensitivity to ionizing radiation, microcephaly and growth retardation. Some patients may manifest SCID with sensitivity to ionizing radiation without microcephaly and mild growth retardation, probably due to hypomorphic NHEJ1 mutations.

DISEASE: Note=A chromosomal aberration involving NHEJ1 is found in a patient with polymicrogyria. Translocation t(2;7)(q35;p22).

MISCELLANEOUS: Was named 'Cernunnos' after the enigmatic Celtic god of hunting, the underworld and fertility.

SIMILARITY: Belongs to the XLF family.
