Anti-C8orf4 antibodies enable researchers to detect and measure the C8orf4 antigen in biological samples. This target is a reported synonym of the TCIM gene, which encodes transcriptional and immune response regulator. This protein is known to function in the apoptotic pathway, among other biological roles. The human version of C8orf4 has a canonical amino acid length of 106 residues and a protein mass of 12.3 kilodaltons. It is reported to be localized in the nucleus and cytoplasm of cells and notably expressed in many tissues, such as the colon, urinary bladder, and breast.
