Nej1p (Saccharomyces cerevisiae) is product of expression of NEJ1 gene.

Nej1p is involved in:

NHEJ in Saccharomyces cerevisiae

FUNCTION: Involved in non-homologous end joining (NHEJ). Facilitates the transport of LIF1 into the nucleus, where it can interact with DNA ligase DNL4 to repair double-strand breaks (DSB). Mediates mating-type regulation of NHEJ. Prevents chromosome circularisation by NHEJ in absence of telomerase.

INTERACTION: P53150:LIF1; NbExp=2; IntAct=EBI-34047, EBI-23865;

SUBCELLULAR LOCATION: Cytoplasm. Nucleus membrane; Multi-pass membrane protein.

INDUCTION: Repressed in diploid cells.

MISCELLANEOUS: Present with 377 molecules/cell in log phase SD medium.

SIMILARITY: Belongs to the XLF family.

NCBI GenPept GI number(s): 296146799
Species: Saccharomyces cerevisiae
