Anti-TRIM40 antibodies are used in the immunodetection of the protein tripartite motif containing 40. In humans, the canonical protein has a reported length of 258 amino acid residues and a mass of 29.3 kDa. Up to 2 different isoforms have been reported for this protein. It is reported to be highly expressed in normal gastrointestinal epithelia but that is down-regulated in gastrointestinal carcinomas and chronic inflammatory lesions of the gastrointestinal tract. A member of the TRIM/RBCC protein family, TRIM40 is known to be involved with innate immune responses and the regulation of cell growth. Synonyms for this target antigen include RING finger protein 35, probable E3 NEDD8-protein ligase, ring finger RNF35, and E3 ubiquitin ligase TRIM40. TRIM40 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. Some TRIM40 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunofluorescence is also a common application.
