Anti-RNF125 antibodies are used in the immunodetection of the protein ring finger protein 125. In humans, the canonical protein has a reported length of 232 amino acid residues and a mass of 26.5 kDa. Its subcellular localization is in the golgi. It is reported to be highly expressed in the lymphoid tissues, including bone marrow, spleen and thymus. Among its functions, RNF125 is involved with adaptive immune responses and protein ubiquitination. Post-translational modifications have been described, including ubiquitination. Synonyms for this target antigen include TRAC-1, TRAC1, E3 ubiquitin-protein ligase RNF125, T-cell RING activation protein 1, T-cell ring protein identified in activation screen, and TNORS.
