Anti-DNAJB13 antibodies are used in the immunodetection of the protein DnaJ heat shock protein family (Hsp40) member B13. In humans, the canonical protein has a reported length of 316 amino acid residues and a mass of 36.1 kDa. Its subcellular localization is in the cell projections. Up to 2 different isoforms have been reported for this protein. It is notably expressed in the testis and trachea. DNAJB13 is known to functions as part of axonemal radial spoke complexes that play an important part in the motility of sperm and cilia. The DNAJB13 gene has been associated with the disease, Ciliary dyskinesia. Synonyms for this target antigen include DnaJ (Hsp40) homolog, subfamily B, member 13, DnaJ (Hsp40) related, subfamily B, member 13, DnaJ-like protein, radial spoke 16 homolog A, and dnaJ homolog subfamily B member 13. DNAJB13 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. ELISA, Western Blot, Immunofluorescence, and Immunohistochemistry are common applications for DNAJB13 antibodies.
