Anti-FAM46B antibodies enable researchers to detect and measure the FAM46B antigen in biological samples. This target is a reported synonym of the TENT5B gene, which encodes terminal nucleotidyltransferase 5B. This protein is known to function in the regulation of apoptosis and the regulation of cell proliferation, among other biological roles. The human version of FAM46B has a canonical amino acid length of 425 residues and a protein mass of 46.7 kilodaltons. It is reported to be localized in the nucleus and cytoplasm of cells. FAM46B is a member of the TENT protein family.
