Subunit of the oligosaccharyl transferase (OST) complex that catalyzes the initial transfer of a defined glycan (Glc(3)Man(9)GlcNAc(2) in eukaryotes) from the lipid carrier dolichol-pyrophosphate to an asparagine residue within an Asn-X-Ser/Thr consensus motif in nascent polypeptide chains, the first step in protein N-glycosylation (PubMed:31831667). N-glycosylation occurs cotranslationally and the complex associates with the Sec61 complex at the channel-forming translocon complex that mediates protein translocation across the endoplasmic reticulum (ER). All subunits are required for a maximal enzyme activity (By similarity).

Ribophorin I also known as RPN1 is a glycoprotein with a mass of approximately 68 kDa. It is located in the rough endoplasmic reticulum (ER) and is part of the oligosaccharyltransferase complex which is involved in the N-linked glycosylation of nascent polypeptides. This protein facilitates the unanimous transfer of oligosaccharides to asparagine residues in polypeptide chains an important step in protein maturation. Ribophorin I shows expression in various tissues but is especially prominent in the liver and pancreas where high levels of protein synthesis occur.
Ribophorin I plays an essential role in the process of protein folding and quality control within the ER. It is part of the oligosaccharyltransferase complex along with other key proteins like STT3A/B and Ribophorin II. The complex ensures that nascent proteins receive the proper glycosylation necessary for proper folding and stability. This process helps maintain a balance between protein production and degradation ensuring that only properly folded proteins proceed to their intended cellular locations.
Ribophorin I functions within the N-linked glycosylation pathway critical for protein maturation and function. Also it takes part in the unfolded protein response pathway which reacts to stress conditions that disrupt the folding processes in the ER. This pathway involves other proteins such as BiP/GRP78 and ATF6 which work together to restore normal protein folding conditions. Ribophorin I's efficient function in these pathways is key to sustaining cellular operations maintaining protein homeostasis.
Ribophorin I is implicated in cancer and neurodegenerative diseases. Its malfunction can disrupt protein glycosylation and folding contributing to the progression of cancer by allowing aberrant glycoproteins on the cell surface. In neurodegenerative disorders like Alzheimer's disease impaired N-linked glycosylation affects protein folding leading to aggregation of misfolded proteins. Ribophorin I interacts indirectly with proteins such as amyloid precursor protein (APP) in Alzheimer's influencing the disease pathology through related glycosylation processes.
