Anti-HSPC154 antibodies enable researchers to detect and measure the HSPC154 antigen in biological samples. This target is a reported synonym of the TIMM21 gene, which encodes translocase of inner mitochondrial membrane 21. This protein is known to function in intracellular protein transport, among other biological roles. The human version of HSPC154 has a canonical amino acid length of 248 residues and a protein mass of 28.2 kilodaltons. It is reported to be localized in the mitochondria of cells. Other names for this target antigen include C18orf55 and TIM21.
