Anti-TIMM17B antibodies are used in the immunodetection of the protein translocase of inner mitochondrial membrane 17B. In humans, the canonical protein has a reported length of 172 amino acid residues and a mass of 18.3 kDa. Its subcellular localization is in the mitochondria. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the Tim17/Tim22/Tim23 protein family, TIMM17B is an important component of the TIM23 complex, a complex that mediates the translocation of transit peptide-containing proteins across the mitochondrial inner membrane. Synonyms for this target antigen include JM3, TIM17B, mitochondrial import inner membrane translocase subunit Tim17-B, inner mitochondrial membrane preprotein translocase, translocase of inner mitochondrial membrane 17 homolog B, and DXS9822. A number of TIMM17B antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
