| GO:0030145 | manganese ion binding | molecular_function | Binding to a manganese ion (Mn). [GOC:ai] |
| GO:0035248 | alpha-1,4-N-acetylgalactosaminyltransferase activity | molecular_function | Catalysis of the transfer of an N-acetylgalactosaminyl residue from UDP-N-acetyl-galactosamine to an acceptor molecule, forming an alpha-1,4 linkage. [PMID:15130086] |
| GO:0047237 | glucuronylgalactosylproteoglycan 4-beta-N-acetylgalactosaminyltransferase activity | molecular_function | Catalysis of the reaction |
| GO:0006044 | N-acetylglucosamine metabolic process | biological_process | The chemical reactions and pathways involving N-acetylglucosamine. The D isomer is a common structural unit of glycoproteins in plants, bacteria and animals; it is often the terminal sugar of an oligosaccharide group of a glycoprotein. [ISBN:0198506732] |
| GO:0015012 | heparan sulfate proteoglycan biosynthetic process | biological_process | The chemical reactions and pathways resulting in the formation of the heparan sulfate proteoglycan, a glycosaminoglycan with repeat unit consisting of alternating alpha-(1->4)-linked hexuronic acid and glucosamine residues; the former are a mixture of sulfated and nonsulfated D-glucuronic acid and L-iduronic acid; the L-iduronic acid is either sulfated or acetylated on its amino group as well as being sulfated on one of its hydroxyl groups; heparan sulfate chains are covalently linked to peptidyl-serine by a glycosidic attachment through the trisaccharide galactosyl-galactosyl-xylosyl to serine residues.

| GO:0019276 | UDP-N-acetylgalactosamine metabolic process | biological_process | The chemical reactions and pathways involving UDP-N-acetylgalactosamine, a substance composed of N-acetylgalactosamine, a common structural unit of oligosaccharides, in glycosidic linkage with uridine diphosphate. [GOC:ai] |
| 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:0005654 | nucleoplasm | cellular_component | That part of the nuclear content other than the chromosomes or the nucleolus. [GOC:ma, ISBN:0124325653] |
| 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] |
| GO:0005789 | endoplasmic reticulum membrane | cellular_component | The lipid bilayer surrounding the endoplasmic reticulum. [GOC:mah] |
| GO:0005829 | cytosol | cellular_component | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. [GOC:hjd, GOC:jl] |
