Anti-ST13 Hsp70 interacting protein antibodies are used for the immunodetection of the protein encoded by the ST13 gene. In humans, the canonical protein has a reported length of 369 amino acid residues and a mass of 41.3 kDa. Its subcellular localization is in the cytoplasm. A member of the FAM10 protein family, it is known to be involved with protein folding. Other names for this target antigen include FAM10A1, FAM10A4, HIP, HOP, HSPABP, HSPABP1, P48, and AAG2. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
