Anti-TRAP3 antibodies enable researchers to detect and measure the TRAP3 antigen in biological samples. This target is a reported synonym of the TRAF2 gene, which encodes TNF receptor associated factor 2. This protein is known to function in innate immune responses and the apoptotic pathway, among other biological roles. The human version of TRAP3 has a canonical amino acid length of 501 residues and a protein mass of 55.9 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the cytoplasm of cells. Other names for this target antigen include MGC:45012, RNF117, and TRAP. ELISA, Western Blot, and Immunohistochemistry are common applications for TRAP3 antibodies.
