Anti-ERP44 antibodies are used in the immunodetection of the protein endoplasmic reticulum protein 44. In humans, the canonical protein has a reported length of 406 amino acid residues and a mass of 47 kDa. Its subcellular localization is in the ER. It is notably widely expressed in many tissue types. ERP44 is known to mediate thiol-dependent retention in the early secretory pathway, forming mixed disulfides with substrate proteins through its conserved CRFS motif. Synonyms for this target antigen include TXNDC4, endoplasmic reticulum resident protein 44, ER protein 44, endoplasmic reticulum resident protein 44 kDa, and PDIA10. ERP44 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of ERp44 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
