Q8IZV2

STT3B

Q8TCJ2

Catalytic subunit of the N-oligosaccharyl transferase(OST) complex which catalyzes the transfer of a high mannoseoligosaccharide from a lipid-linked oligosaccharide donor to anasparagine residue within an Asn-X-Ser/Thr consensus motif innascent polypeptide chains. N-glycosylation occurscotranslationally and the complex associates with the Sec61complex at the channel-forming translocon complex that mediatesprotein translocation across the endoplasmic reticulum (ER). STT3Bis present in a small subset of OST complexes and mediates bothcotranslational and post-translational N-glycosylation of targetproteins: STT3B-containing complexes are required for efficientpost-translational glycosylation and while they are less competentthan STT3A-containing complexes for cotranslational glycosylation,they have the ability to mediate glycosylation of some nascentsites that are not accessible for STT3A. STT3B-containingcomplexes also act post-translationally and mediate modificationof skipped glycosylation sites in unfolded proteins. Plays a rolein ER-associated degradation (ERAD) pathway that mediatesubiquitin-dependent degradation of misfolded endoplasmic reticulumproteins by mediating N-glycosylation of unfolded proteins, whichare then recognized by the ERAD pathway and targeted fordegradation. Mediates glycosylation of the disease variant AMYL-TTR 'Asp-38' of TTR at 'Asn-118', leading to its degradation.{ECO:0000269|PubMed:19167329, ECO:0000269|PubMed:22607976,ECO:0000305}.
