Clone Host Grade Applications
Polyclonal Rabbit Affinity Purified B IP IH IC
Calnexin is a calcium-binding protein which interacts with newly synthesized glycoproteins in ER for facilitating protein assembly and/or the retention within ER of unassembled protein subunits as well as incorrectly folded proteins thereby playing a key role in ER's quality control apparatus. The specificity of calnexin for glycoproteins is defined by a lectin site, which binds an early oligosaccharide intermediate on the folding glycoprotein. When associated with partial T-cell antigen receptor complexes which escape immature thymocytes's ER, calnexin regulates thymocyte maturation process and is also implicated in receptor-mediated endocytosis at synapses. MAPK3/ERK1 phosphorylates calnexin at Ser-565 leading to increased calnexin-ribosomal association and DHHC6 mediated calnexin palmitoylation leads to its preferential localization to perinuclear rough ER. Palmitoylation also facilitate calnexin association with RTC/ribosome-translocon complex that is essential to efficient folding of glycosylated proteins.
