| GO:0004571 | mannosyl-oligosaccharide 1,2-alpha-mannosidase activity | molecular_function | Catalysis of the hydrolysis of the terminal (1->2)-linked alpha-D-mannose residues in an oligo-mannose oligosaccharide. [GOC:bf, PMID:25092655] |
| GO:0005509 | calcium ion binding | molecular_function | Binding to a calcium ion (Ca2+). [GOC:ai] |
| GO:0005975 | carbohydrate metabolic process | biological_process | The chemical reactions and pathways involving carbohydrates, any of a group of organic compounds based of the general formula Cx(H2O)y. [GOC:mah, ISBN:0198506732] |
| GO:0006058 | mannoprotein catabolic process | biological_process | The chemical reactions and pathways resulting in the breakdown of a mannoprotein, a protein that contains covalently bound mannose residues. [ISBN:0198506732] |
| GO:0006486 | protein glycosylation | biological_process | A protein modification process that results in the addition of a carbohydrate or carbohydrate derivative unit to a protein amino acid, e.g. the addition of glycan chains to proteins. [GOC:curators, GOC:pr] |
| GO:0006986 | response to unfolded protein | biological_process | Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an unfolded protein stimulus. [GOC:jl] |
| GO:0036503 | ERAD pathway | biological_process | The protein catabolic pathway which targets endoplasmic reticulum (ER)-resident proteins for degradation by the cytoplasmic proteasome. It begins with recognition of the ER-resident protein, includes retrotranslocation (dislocation) of the protein from the ER to the cytosol, protein modifications necessary for correct substrate transfer (e.g. ubiquitination), transport of the protein to the proteasome, and ends with degradation of the protein by the cytoplasmic proteasome. [GOC:bf, GOC:PARL, PMID:20940304, PMID:21969857] |
| GO:0005788 | endoplasmic reticulum lumen | cellular_component | The volume enclosed by the membranes of the endoplasmic reticulum. [ISBN:0198547684] |
| GO:0016020 | membrane | cellular_component | A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it. [GOC:dos, GOC:mah, ISBN:0815316194] |
| GO:0044322 | endoplasmic reticulum quality control compartment | cellular_component | A subcompartment of the endoplasmic reticulum in which proteins with improper or incorrect folding accumulate. Enzymes in this compartment direct proteins with major folding problems to translocation to the cytosol and degradation, and proteins with minor folding problems to the ER, to interact with chaperon proteins. [PMID:11408579] |
| GO:1904380 | endoplasmic reticulum mannose trimming | biological_process | Any protein alpha-1,2-demannosylation that takes place in the endoplasmic reticulum quality control compartment (ERQC). [GO_REF:0000062, GOC:bf, GOC:PARL, GOC:TermGenie, PMID:24519966] |
| GO:1904382 | mannose trimming involved in glycoprotein ERAD pathway | biological_process | The removal of one or more alpha 1,2-linked mannose residues from a mannosylated protein that occurs as part of glycoprotein ER-associated glycoprotein degradation (gpERAD). [GO_REF:0000060, GOC:bf, GOC:PARL, GOC:TermGenie, PMID:24519966] |
| GO:0005783 | endoplasmic reticulum | cellular_component | The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached). [ISBN:0198506732] |
