Product Description

PA1-903 detects calreticulin from human, rat, mouse, hamster, rabbit and canine tissues. PA1-903 has been successfully used in Western blot, immunoprecipitation, immunocytochemistry and immunofluorescence procedures. By Western blot, this antibody detects an ~60 kDa protein representing calreticulin and an ~120 kDa unidentified protein from rat brain extract. PA1-903 immunizing peptide corresponds to amino acid residues 399-414 from mouse calreticulin. PA1-903 immunizing peptide (Cat. # PEP-017) is available for use in neutralization and control experiments. Calr or Calreticulin is a calcium-binding chaperone that promotes folding, oligomeric assembly and quality control in the endoplasmic reticulum (ER) via the calreticulin/calnexin cycle. Calr, a lectin, interacts transiently with almost all of the monoglucosylated glycoproteins that are synthesized in the ER. Calr also interacts with with the DNA-binding domain of NR3C1 and mediates its nuclear export. It may also be involved in maternal gene expression regulation and oocyte maturation via the regulation of calcium homeostasis.
