Anti-DEG1 antibodies enable researchers to detect and measure the DEG1 antigen in biological samples. This target is a reported synonym of the PUS3 gene, which encodes pseudouridine synthase 3. The human version of DEG1 has a canonical amino acid length of 481 residues and a protein mass of 55.6 kilodaltons. It is reported to be localized in the nucleus of cells. DEG1 is a member of the TRNA pseudouridine synthase TruA protein family.
