| GO:0005794 | 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] |
| GO:0004653 | polypeptide N-acetylgalactosaminyltransferase activity | molecular_function | Catalysis of the reaction |
| GO:0005515 | protein binding | molecular_function | Binding to a protein. [GOC:go_curators] |
| GO:0030145 | manganese ion binding | molecular_function | Binding to a manganese ion (Mn). [GOC:ai] |
| GO:0030246 | carbohydrate binding | molecular_function | Binding to a carbohydrate, which includes monosaccharides, oligosaccharides and polysaccharides as well as substances derived from monosaccharides by reduction of the carbonyl group (alditols), by oxidation of one or more hydroxy groups to afford the corresponding aldehydes, ketones, or carboxylic acids, or by replacement of one or more hydroxy group(s) by a hydrogen atom. Cyclitols are generally not regarded as carbohydrates. [GOC:mah] |
| GO:0006493 | protein O-linked glycosylation | biological_process | A protein glycosylation process in which a carbohydrate or carbohydrate derivative unit is added to a protein via the hydroxyl group of peptidyl-serine, peptidyl-threonine, peptidyl-hydroxylysine, or peptidyl-hydroxyproline, or via the phenol group of peptidyl-tyrosine, forming an O-glycan.

| GO:0016266 | O-glycan processing | biological_process | The stepwise addition of carbohydrate or carbohydrate derivative residues to the initially added O-linked residue (usually GalNAc) to form a core O-glycan structure. [GOC:mah, GOC:pr, PMID:10580130] |
| GO:0018242 | protein O-linked glycosylation via serine | biological_process | The glycosylation of protein via the O3 atom of peptidyl-serine, forming O3-glycosyl-L-serine; the most common forms are N-acetylgalactosaminyl, mannosyl, galactosyl, and xylosyl serine. [RESID:AA0154] |
| GO:0018243 | protein O-linked glycosylation via threonine | biological_process | The glycosylation of protein via the O3 atom of peptidyl-threonine, forming O3-glycosyl-L-threonine; the most common forms are N-acetylgalactosaminyl, mannosyl, and galactosyl threonine. [RESID:AA0155] |
| GO:0051604 | protein maturation | biological_process | Any process leading to the attainment of the full functional capacity of a protein. [GOC:ai] |
| GO:0000139 | Golgi membrane | cellular_component | The lipid bilayer surrounding any of the compartments of the Golgi apparatus. [GOC:mah] |
| GO:0005576 | extracellular region | cellular_component | The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite. [GOC:go_curators] |
| GO:0005789 | endoplasmic reticulum membrane | cellular_component | The lipid bilayer surrounding the endoplasmic reticulum. [GOC:mah] |
| GO:0005795 | Golgi stack | cellular_component | The set of thin, flattened membrane-bounded compartments, called cisternae, that form the central portion of the Golgi complex. The stack usually comprises cis, medial, and trans cisternae; the cis- and trans-Golgi networks are not considered part of the stack. [GOC:mah, ISBN:0815316194] |
| 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:0032580 | Golgi cisterna membrane | cellular_component | The lipid bilayer surrounding any of the thin, flattened compartments that form the central portion of the Golgi complex. [GOC:ecd, GOC:mah] |
| GO:0048471 | perinuclear region of cytoplasm | cellular_component | Cytoplasm situated near, or occurring around, the nucleus. [GOC:jid] |
