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.

The chemical reactions and pathways involving carbohydrates, any of a group of organic compounds based of the general formula Cx(H2O)y. Includes the formation of carbohydrate derivatives by the addition of a carbohydrate residue to another molecule.

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.

The series of molecular signals generated as a consequence of a fibroblast growth factor receptor binding to one of its physiological ligands.

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.

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.

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.

The lipid bilayer surrounding any of the compartments of the Golgi apparatus.

A compound membranous cytoplasmic organelle of eukaryotic cells, consisting of flattened, ribosome-free vesicles arranged in a more or less regular stack. The Golgi apparatus differs from the endoplasmic reticulum in often having slightly thicker membranes, appearing in sections as a characteristic shallow semicircle so that the convex side (cis or entry face) abuts the endoplasmic reticulum, secretory vesicles emerging from the concave side (trans or exit face). In vertebrate cells there is usually one such organelle, while in invertebrates and plants, where they are known usually as dictyosomes, there may be several scattered in the cytoplasm. The Golgi apparatus processes proteins produced on the ribosomes of the rough endoplasmic reticulum; such processing includes modification of the core oligosaccharides of glycoproteins, and the sorting and packaging of proteins for transport to a variety of cellular locations. Three different regions of the Golgi are now recognized both in terms of structure and function: cis, in the vicinity of the cis face, trans, in the vicinity of the trans face, and medial, lying between the cis and trans regions.

Cytoplasm situated near, or occurring around, the nucleus.

Cytoplasm situated near, or occurring around, the nucleus.

A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.

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.

A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.
