5 GO annotations of cellular component
| Name | Definition |
|---|---|
| endoplasmic reticulum membrane | The lipid bilayer surrounding the endoplasmic reticulum. |
| integral component of membrane | The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane. |
| membrane | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
| oligosaccharyltransferase complex | A protein complex that is found in the endoplasmic reticulum membrane of eukaryotes and transfers lipid-linked oligosaccharide precursor to asparagine residues on nascent proteins. In yeast, the complex includes at least nine different subunits, whereas in mammalian cells at least three different forms of the complex have been detected. |
| oligosaccharyltransferase III complex | An oligosaccharyltransferase (OST) complex that contains the seven polypeptides found in OST complex I, plus heterotrimeric Sec61alpha-beta-gamma and the tetrameric TRAP complex. Of the three forms of mammalian OST complexes identified, the OSTIII complex has the strongest affinity for ribosomes. |
2 GO annotations of molecular function
| Name | Definition |
|---|---|
| dolichyl-diphosphooligosaccharide-protein glycotransferase activity | Catalysis of the reaction: dolichyl diphosphooligosaccharide + protein L-asparagine = dolichyl diphosphate + a glycoprotein with the oligosaccharide chain attached by glycosylamine linkage to protein L-asparagine. |
| metal ion binding | Binding to a metal ion. |
4 GO annotations of biological process
| Name | Definition |
|---|---|
| co-translational protein modification | The process of covalently altering one or more amino acids in a protein after translation has begun but before the protein has been released from the ribosome. |
| post-translational protein modification | The process of covalently altering one or more amino acids in a protein after the protein has been completely translated and released from the ribosome. |
| protein N-linked glycosylation | A protein glycosylation process in which a carbohydrate or carbohydrate derivative unit is added to a protein via the N4 atom of peptidyl-asparagine, the omega-N of arginine, or the N1' atom peptidyl-tryptophan. |
| protein N-linked glycosylation via asparagine | The glycosylation of protein via the N4 atom of peptidyl-asparagine forming N4-glycosyl-L-asparagine; the most common form is N-acetylglucosaminyl asparagine; N-acetylgalactosaminyl asparagine and N4 glucosyl asparagine also occur. This modification typically occurs in extracellular peptides with an N-X-(ST) motif. Partial modification has been observed to occur with cysteine, rather than serine or threonine, in the third position; secondary structure features are important, and proline in the second or fourth positions inhibits modification. |
