The o-glcnac modification
Web1 day ago · Arabidopsis thaliana has two glycosyl transferases, SPINDLY (SPY) and SECRET AGENT (SEC), that modify nuclear and cytosolic protein with O-linked fucose and N-acetylglucosamine (GlcNAc), respectively. SPY interacts physically and genetically with GIGANTEA (GI). Previously, we reported that SEC substrates are O-GlcNAc modified when … WebMar 8, 2024 · O-linked N -acetylglucosamine ( O -GlcNAc) is an essential and dynamic post-translational modification that is presented on thousands of nucleocytoplasmic proteins.

WebMar 6, 2015 · O -GlcNAcase is a soluble, highly conserved enzyme, and expressed in all eukaryotic organisms involved with the removal of O -GlcNAc modification from proteins. 53O -GlcNAcase is primarily located in the cytoplasm with an optimum pH of 5.5 to 7 and coded for by a single gene. WebPost-translational modification with O-linked β-N-acetylglucosamine (O-GlcNAc), a process referred to as O-GlcNAcylation, occurs on a vast variety of proteins. Mounting evidence in …
WebMay 17, 2024 · Notably, the pattern of this labeling was consistent with O-GlcNAc modifications, suggesting that the enzyme O-GlcNAc transferase is quite promiscuous for its donor sugar substrates. To confirm this possibility, we show that 6AzGlc-treatment results in the labeling of known O-GlcNAcylated proteins, ... WebOur ability to identify and unambiguously assign the site of O-GlcNAc modifications using ETD is rapidly increasing our understanding of this regulatory glycosylation and its …
WebTo probe for O-GlcNAc modification on clock proteins, we first performed immunoprecipitation essentially as previously described (Sun et al. 2010). To protein extracts from S2 cells and fly head extracts, we added 3 μL of anti-PER (GP339), anti-CLK(GP208), anti-HA(12CA5), or anti-Flag (M2) antibody, depending on the target protein … WebThe three major types of O -linked glycosylation found on the EGF repeats of Notch pathway components are O -fucosylation, O -glucosylation, and O - N -acetylglucosamine (GlcNAc) modification, which exist as monosaccharides or extended forms. Figure 2. O -Glycosylation in the Notch EGF repeats.
WebDec 9, 2024 · To directly demonstrate the O -GlcNAc modification of eIF3a, we incubated cells with azide-modified glucosamine followed by a click chemical reaction. eIF3a was readily pulled down by biotin from...
WebThe presence of the O-α-GlcNAc modification has complicated the analysis of O-β-GlcNAc in protozoa; however, O-GlcNAc and OGT have been reported in Giardia lamblia and Cryptosporidium parvum. O-GlcNAc–modified proteins have also been found on many viruses that infect metazoans (e.g., adenovirus, SV40, cytomegalovirus, rotavirus, … tim mcelweeWebO-GlcNAc modification also accelerated passive permeation of a small, inert protein through NPCs. We conclude that O-GlcNAc modification accelerates nucleocytoplasmic transport by enhancing the nonspecific permeability of the FG-repeat barrier, perhaps by steric inhibition of interactions between FG repeats. tim mcelhiney facebookWebSep 26, 2012 · O-GlcNAc modification of protein kinase C (PKC) PKC comprises a family of 10 lipid-dependent serine/threonine kinases that play key roles in proliferation and cell … tim mcelwainWebMar 29, 2024 · In addition, O-GlcNAc modification of the transcription factor HIF-1 also plays a key role in regulating metabolism (Ferrer et al. 2014; Courtnay et al. 2015). HIF-1 is a transcription factor whose stability has been shown to responsive to O-GlcNAc modification (Yang et al. 2015b). parks canada reservations log inWebOct 12, 2015 · O-GlcNAc has been identified as an in vivo, endogenous modification of α-synuclein at threonine 64 and 72 in mice and serine 87 in humans, residues that are conserved between the species 8, 9,... tim mcelhinnyWebKim et al. (2012) show that the circadian negative regulator dPER in Drosophila is modified by O -GlucNAcylation, which impacts on subcellular localization and turnover of the protein and affects the circadian period length.
