Anti-TIM4 antibodies enable researchers to detect and measure the TIM4 antigen in biological samples. This target is a reported synonym of the TIMD4 gene, which encodes T cell immunoglobulin and mucin domain containing 4. This protein is known to function in the apoptotic pathway, among other biological roles. The human version of TIM4 has a canonical amino acid length of 378 residues and a protein mass of 41.6 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cell membrane of cells and notably expressed in the tonsil, testis, spleen, lymph node, and bone marrow. Other names for this target antigen include T-cell immunoglobulin, and mucin domain-containing protein 4, T-cell immunoglobulin mucin receptor 4, and T-cell membrane protein 4.
