WebJun 4, 2024 · GalNAc-type O-glycosylation is initiated in the Golgi, and the cellular repertoire of expressed GalNAc-Ts determine which proteins and the positions in these that are glycosylated. Most cell types express 3–6 GalNAc-T isoforms out of the 20 available GALNT genes, and it is estimated that over 80% of proteins trafficking the secretory … WebFeb 2, 2024 · Chemokine receptors have either reported or predicted sites of N-acetyl galactosamine (GalNAc)-type O-glycosylation in their N-termini . In addition, they may be modified by tyrosine sulfation and a general co-localization of these two PTMs may be a common finding for chemotactic receptors . These two post-translational modifications …
