CC -!- FUNCTION: Subunit of the oligosaccharyl transferase (OST) complex that
CC catalyzes the initial transfer of a defined glycan
CC (Glc(3)Man(9)GlcNAc(2) in eukaryotes) from the lipid carrier dolichol-
CC pyrophosphate to an asparagine residue within an Asn-X-Ser/Thr
CC consensus motif in nascent polypeptide chains, the first step in
CC protein N-glycosylation. N-glycosylation occurs cotranslationally and
CC the complex associates with the Sec61 complex at the channel-forming
CC translocon complex that mediates protein translocation across the
CC endoplasmic reticulum (ER). All subunits are required for a maximal
CC enzyme activity. {ECO:0000250|UniProtKB:E2R4X3}.
CC -!- PATHWAY: Protein modification; protein glycosylation.
CC {ECO:0000250|UniProtKB:P61803}.
CC -!- SUBUNIT: Component of the oligosaccharyltransferase (OST) complex. OST
CC exists in two different complex forms which contain common core
CC subunits RPN1, RPN2, OST48, OST4, DAD1 and TMEM258, either STT3A or
CC STT3B as catalytic subunits, and form-specific accessory subunits.
CC STT3A complex assembly occurs through the formation of 3 subcomplexes.
CC Subcomplex 1 contains RPN1 and TMEM258, subcomplex 2 contains the
CC STT3A-specific subunits STT3A, DC2/OSTC, and KCP2 as well as the core
CC subunit OST4, and subcomplex 3 contains RPN2, DAD1, and OST48. The
CC STT3A complex can form stable complexes with the Sec61 complex or with
CC both the Sec61 and TRAP complexes. {ECO:0000250|UniProtKB:E2R4X3}.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane; Multi-pass
CC membrane protein {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the DAD/OST2 family. {ECO:0000305}.
