Anti-SNM1B antibodies enable researchers to detect and measure the SNM1B antigen in biological samples. This target is a reported synonym of the DCLRE1B gene, which encodes DNA cross-link repair 1B. This protein is reported to be a 5'-3' exonuclease that plays a central role in telomere maintenance and protection during S-phase. The human version of SNM1B has a canonical amino acid length of 532 residues and a protein mass of 60 kilodaltons. It is reported to be localized in the nucleus, chromosomes, and cytoplasm of cells. SNM1B is a member of the DNA repair metallo-beta-lactamase (DRMBL) protein family.
