Listed are ELISA Kits for the detection of nonhomologous end-joining factor 1, an alias name of non-homologous end joining factor 1. The human protein, encoded by the gene NHEJ1, is 299 amino acid residues long and has a mass of 33,337 daltons. However, there are up to 2 reported isoforms. It is a member of the XLF family. This protein is reported to have a nuclear cellular localization. The gene is associated with Severe combined immunodeficiency due to NHEJ1 deficiency. This target may also be known as: XRCC4-like factor, nonhomologous end-joining factor 1, protein cernunnos, and XLF.
