Anti-DNAJC13 antibodies are used in the immunodetection of the protein DnaJ heat shock protein family (Hsp40) member C13. In humans, the canonical protein has a reported length of 2243 amino acid residues and a mass of 254.4 kDa. Its subcellular localization is in the membrane. DNAJC13 is known to be involved in membrane trafficking through early endosomes, such as the early endosome to recycling endosome transport implicated in the recycling of transferrin and the early endosome to late endosome transport implicated in degradation of EGF and EGFR. Synonyms for this target antigen include RME8, dnaJ homolog subfamily C member 13, DnaJ (Hsp40) homolog, subfamily C, member 13, DnaJ domain-containing protein RME-8, required for receptor-mediated endocytosis 8, and PARK21.
