Other Names | Oligosaccharyltransferase complex subunit OSTC, Hydrophobic protein HSF-28, OSTC |
Target/Specificity | This OSTC antibody is generated from rabbits immunized with a KLH conjugated synthetic peptide between 90-117 amino acids from the C-terminal region of human OSTC. |
Dilution | WB~~1:1000 |
Format | Purified polyclonal antibody supplied in PBS with 0.09% (W/V) sodium azide. This antibody is purified through a protein A column, followed by peptide affinity purification. |
Storage | Maintain refrigerated at 2-8°C for up to 2 weeks. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles. |
Precautions | OSTC Antibody (C-term) is for research use only and not for use in diagnostic or therapeutic procedures. |
Name | OSTC (HGNC:24448) |

Function | Subunit of STT3A-containing oligosaccharyl transferase (OST- A) 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:28860277, PubMed:31831667, PubMed:39509507). 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) (PubMed:28860277, PubMed:31831667, PubMed:39509507). Within the OST-A complex, acts as an adapter that anchors the OST-A complex to the Sec61 complex (PubMed:28860277). May be involved in N-glycosylation of APP (amyloid-beta precursor protein) (PubMed:21768116). Can modulate gamma-secretase cleavage of APP by enhancing endoprotelysis of PSEN1 (PubMed:21768116). |
