This protein enables 2 target(s):
| Target | Category | Definition |
|---|---|---|
| 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] |
| calcium ion binding | molecular function | Binding to a calcium ion (Ca2+). [GOC:ai] |
This protein is located in 7 target(s):
| Target | Category | Definition |
|---|---|---|
| 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] |
| endoplasmic reticulum membrane | cellular component | The lipid bilayer surrounding the endoplasmic reticulum. [GOC:mah] |
| Golgi apparatus | cellular component | A membrane-bound cytoplasmic organelle of the endomembrane system that further processes the core oligosaccharides (e.g. N-glycans) added to proteins in the endoplasmic reticulum and packages them into membrane-bound vesicles. The Golgi apparatus operates at the intersection of the secretory, lysosomal, and endocytic pathways. [ISBN:0198506732] |
| 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] |
| cytoplasmic vesicle | cellular component | A vesicle found in the cytoplasm of a cell. [GOC:ai, GOC:mah, GOC:vesicles] |
| 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] |
| extracellular vesicle | cellular component | Any vesicle that is part of the extracellular region. [GO_REF:0000064, GOC:pm, GOC:TermGenie, PMID:24769233] |

| 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] |
| 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] |
| oligosaccharide metabolic process | biological process | The chemical reactions and pathways involving oligosaccharides, molecules with between two and (about) 20 monosaccharide residues connected by glycosidic linkages. [ISBN:0198506732] |
| viral protein processing | biological process | Any protein maturation process achieved by the cleavage of a peptide bond or bonds within a viral protein. [GOC:bf, GOC:jl, ISBN:0781702534] |
| 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.

| protein alpha-1,2-demannosylation | biological process | The removal of one or more alpha 1,2-linked mannose residues from a mannosylated protein. [GOC:bf, GOC:PARL, PMID:21062743, PMID:25092655] |
| 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).
