  • Ribophorin-1
Background InformationDolichyl-diphosphooligosaccharide-protein glycosyltransferase subunit 1 (EC 2.4.99.18; UniProt P04843; also known as Dolichyl-diphosphooligosaccharide-protein glycosyltransferase 67 kDa subunit, Ribophorin I, RPN-I, Ribophorin-1) is encoded by the RPN1 gene (Gene ID 6184) in human. Ribophorin I is an ER transmembrane protein and a subunit of the mammalian Oligosaccharyltransferase (OST) complex. Ribophorin I binds newly synthesized target proteins and delivers them to the catalytic core of the OST complex. Association of ribophorin I with newly synthesized membrane proteins was observed after the exit of the nascent chain from the Sec61 translocon, and it was unaffected by the N-glycosylation status. Ribophorin I is reported to preferentially interact with misfolded over native ribonuclease A. In addition, Ribophorin I is shown to complex with another ER protein malectin and enhance malectin's ability to prevent the secretion of the folding-defective proteins.

Key Applications
  • Western Blotting
Application NotesWestern Blotting Analysis: An 1:5,000 dilution from a representative lot detected ribophorin I in in 25 µg of HeLa cell lysate (Courtesy of Dr. Christopher V. Nicchitta, Duke University Medical Center, Durham, NC).
Western Blotting Analysis: A representative lot detected ribophorin I in the alkali-extracted and Triton X-114-selected integral membrane fraction derived from UV-cross-linked canine pancreas rough microsomes (RM) preparation (Jagannathan, S., et al. (2014). J. Biol. Chem. 2014, 289(37):25907-25924).
Western Blotting Analysis: A representative lot detected ribophorin I in both the Brij35-sensitive (BrS) and Brij35-resistant (BrR) fraction of HeLa ER membrfane proteins (Jagannathan, S., et al. (2014). J. Biol. Chem. 2014, 289(37):25907-25924).
Western Blotting Analysis: A representative lot detected ribophorin I associated with the rRNA-free poly(A) messenger ribonucleoproteins (mRNPs) purified by oligo(dT) from UV-cross-linked canine pancreas rough microsomes (RM) preparation (Jagannathan, S., et al.
