Anti-RCN3 antibodies are used in the immunodetection of the protein reticulocalbin 3. In humans, the canonical protein has a reported length of 328 amino acid residues and a mass of 37.5 kDa. Its subcellular localization is in the ER. It is widely expressed across many tissue types. A member of the CREC protein family, RCN3 is a suspected molecular chaperone assisting protein biosynthesis and transport in the endoplasmic reticulum. Post-translational modifications have been described, including N-glycosylation. Synonyms for this target antigen include reticulocabin, reticulocalbin 3, EF-hand calcium binding domain, and EF-hand calcium-binding protein RLP49. RCN3 gene orthologs have been reported in the mouse, rat, bovine, zebrafish and chimpanzee species. Some RCN3 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
