Anti-DNAJC27 antibodies are used in the immunodetection of the protein DnaJ heat shock protein family (Hsp40) member C27. In humans, the canonical protein has a reported length of 273 amino acid residues and a mass of 30.9 kDa. Its subcellular localization is in the nucleus. Up to 3 different isoforms have been reported for this protein. It is notably expressed in gastrointestinal cancers; expression correlates with later tumor-node-metastasis stages of colorectal cancers. A member of the Rab protein family, DNAJC27 is known to be involved with intracellular protein transport and the regulation of the ERK1 and ERK2 signaling cascade. Synonyms for this target antigen include RabJS, dnaJ homolog subfamily C member 27, DnaJ (Hsp40) homolog, subfamily C, member 27, Ras-associated protein Rap1, rab and DnaJ domain-containing protein, and RBJ. DNAJC27 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. These DNAJC27 antibodies are widely used in Western Blot experiments, among other applications.
