Chain A   (MNS1_YEAST | P32906)
molecular function
    GO:0005509    calcium ion binding    Interacting selectively and non-covalently with calcium ions (Ca2+).
    GO:0016787    hydrolase activity    Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3.
    GO:0016798    hydrolase activity, acting on glycosyl bonds    Catalysis of the hydrolysis of any glycosyl bond.
    GO:0004571    mannosyl-oligosaccharide 1,2-alpha-mannosidase activity    Catalysis of the hydrolysis of the terminal (1->2)-linked alpha-D-mannose residues in an oligo-mannose oligosaccharide.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
biological process
    GO:0006491    N-glycan processing    The conversion of N-linked glycan (N = nitrogen) structures from the initially transferred oligosaccharide to a mature form, by the actions of glycosidases and glycosyltransferases. The early processing steps are conserved and play roles in glycoprotein folding and trafficking.
    GO:0008152    metabolic process    The chemical reactions and pathways, including anabolism and catabolism, by which living organisms transform chemical substances. Metabolic processes typically transform small molecules, but also include macromolecular processes such as DNA repair and replication, and protein synthesis and degradation.
    GO:0035977    protein deglycosylation involved in glycoprotein catabolic process    The removal of sugar residues from a glycosylated protein that contributes to the breakdown of a glycoprotein.
    GO:0006486    protein glycosylation    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.
    GO:0030433    ubiquitin-dependent ERAD pathway    The series of steps necessary to target endoplasmic reticulum (ER)-resident proteins for degradation by the cytoplasmic proteasome. Begins with recognition of the ER-resident protein, includes retrotranslocation (dislocation) of the protein from the ER to the cytosol, protein ubiquitination necessary for correct substrate transfer, transport of the protein to the proteasome, and ends with degradation of the protein by the cytoplasmic proteasome.
    GO:0097466    ubiquitin-dependent glycoprotein ERAD pathway    An ERAD pathway whereby endoplasmic reticulum (ER)-resident glycoproteins are targeted for degradation. Includes differential processing of the glycoprotein sugar chains, retrotranslocation to the cytosol and degradation by the ubiquitin-proteasome pathway. A glycoprotein is a compound in which a carbohydrate component is covalently bound to a protein component.
cellular component
    GO:0005783    endoplasmic reticulum    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).
    GO:0005789    endoplasmic reticulum membrane    The lipid bilayer surrounding the endoplasmic reticulum.
    GO:0016021    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.
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
