Anti-TBC1D13 antibodies are used in the immunodetection of the protein TBC1 domain family member 13. In humans, the canonical protein has a reported length of 400 amino acid residues and a mass of 46.6 kDa. Its subcellular localization is in the membrane and cytoplasm. Up to 3 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. TBC1D13 is known to act as a GTPase-activating protein for RAB35. Synonyms for this target antigen include epididymis secretory sperm binding protein. TBC1D13 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Western Blot is the most common application for the TBC1D13 antibodies listed below. Immunofluorescence and Immunohistochemistry are also common applications.
