Rahmani S, Ahmed H, Ibazebo O, Fussner-Dupas E, Wakarchuk WW, Antonescu CN. O-GlcNAc transferase modulates the cellular endocytosis machinery by controlling the formation of clathrin-coated pits. The Journal of biological chemistry 2023 299(3) 36731797
Abstract:
Clathrin-mediated endocytosis (CME) controls the internalization and function of a wide range of cell surface proteins. CME occurs by the assembly of clathrin and many other proteins on the inner leaflet of the plasma membrane into clathrin-coated pits (CCPs). These structures recruit specific cargo destined for internalization, generate membrane curvature, and in many cases undergo scission from the plasma membrane to yield intracellular vesicles. The diversity of functions of cell surface proteins controlled via internalization by CME may suggest that regulation of CCP formation could be effective to allow cellular adaptation under different contexts. Of interest is how cues derived from cellular metabolism may regulate CME, given the reciprocal role of CME in controlling cellular metabolism. The modification of proteins with O-linked β-GlcNAc (O-GlcNAc) is sensitive to nutrient availability and may allow cellular adaptation to different metabolic conditions. Here, we examined how the modification of proteins with O-GlcNAc may control CCP formation and thus CME. We used perturbation of key enzymes responsible for protein O-GlcNAc modification, as well as specific mutants of the endocytic regulator AAK1 predicted to be impaired for O-GlcNAc modification. We identify that CCP initiation and the assembly of clathrin and other proteins within CCPs are controlled by O-GlcNAc protein modification. This reveals a new dimension of regulation of CME and highlights the important reciprocal regulation of cellular metabolism and endocytosis.

Luo Y, Wang Y, Tian Y, Zhou H, Wen L. "Two Birds One Stone" Strategy for the Site-Specific Analysis of Core Fucosylation and O-GlcNAcylation. Journal of the American Chemical Society 2023 37340703
Abstract:
Core fucosylation and O-GlcNAcylation are the two most famous protein glycosylation modifications that regulate diverse physiological and pathological processes in living organisms. Here, a "two birds one stone" strategy has been described for the site-specific analysis of core fucosylation and O-GlcNAcylation. Taking advantage of two mutant endoglycosidases (EndoF3-D165A and EndoCC-N180H), which efficiently and specifically recognize core fucose and O-GlcNAc, glycopeptides can be labeled using a biantennary N-glycan probe bearing azido and oxazoline groups. Then, a temperature-sensitive poly(N-isopropylacrylamide) polymer functionalized with dibenzocyclooctyne was introduced to facilitate the enrichment of the labeled glycopeptides from the complex mixture. The captured glycopeptides can be further released enzymatically by wild-type endoglycosidases (EndoF3 and EndoCC) in a traceless manner for mass spectrometry (MS) analysis. The described strategy allows simultaneous profiling of core-fucosylated glycoproteome and O-GlcNAcylated glycoproteome from one complex sample by MS technology and searching the database using different variable modifications.
