Anti-STARD13 antibodies are used in the immunodetection of the protein StAR related lipid transfer domain containing 13. In humans, the canonical protein has a reported length of 1113 amino acid residues and a mass of 125 kDa. Its subcellular localization is in the membrane, mitochondria, and cytoplasm. Up to 5 different isoforms have been reported for this protein. It is ubiquitously expressed across many tissue types. STARD13 is a GTPase-activating protein for RhoA, and perhaps for Cdc42. Synonyms for this target antigen include Rho GTPase activating protein on chromosome 13q12, StAR-related lipid transfer (START) domain containing 13, deleted in liver cancer 2 protein, and stAR-related lipid transfer protein 13. STARD13 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of STARD13 antibodies have been mentioned in research publications and have associated citations. ELISA, Western Blot, Immunocytochemistry, and Immunofluorescence are common applications for these antibodies.
