Glycosylation in the golgi complex

WebOct 25, 2024 · The proteins are transferred to the Golgi complex from the endoplasmic reticulum lumen where the N-linked sugars are modified again. Some of the proteins undergo O-linked glycosylation. WebThe Golgi apparatus (/ ˈ ɡ ɒ l dʒ i /), also known as the Golgi complex, Golgi body, or simply the Golgi, is an organelle found in most eukaryotic cells. ... Other general post-translational modifications of proteins include the addition of carbohydrates (glycosylation) and phosphates (phosphorylation).

WebN- and O-linked glycosylation. N-linked glycosylation is through the side chain amide nitrogen of a specific asparagine residue, while O-linked glycosylation is through the oxygen atom in the side chain of serine or threonine residues. The N-linked modification takes place in both ER and Golgi, while the O-linked glycosylation in higher eukaryotes WebAt mammalian neuronal synapses, synaptic vesicle (SV) glycoproteins are essential for robust neurotransmission.
