Deacetylation lc3
WebJan 8, 2015 · Summary. The protein LC3 is indispensible for the cellular recycling process of autophagy and plays critical roles during cargo recruitment, autophagosome biogenesis, and completion. Here, we report that LC3 is phosphorylated at threonine 50 (Thr50) by the mammalian Sterile-20 kinases STK3 and STK4. Loss of phosphorylation at this site … WebWe have previously reported that LC3 deacetylation is an essential event during lipidation. However, the physio-logical significance of LC3 acetylation remained largely unclear [3]. More specifically, it was reported that, in nutritive state, cellular LC3 had two distinct forms, a more abundant soluble form (mostly acetylated) and a

WebAug 2, 2024 · Live cell imaging with GFP-tagged LC3 in L6 myocytes indicated that the cycle of acetylation-deacetylation allows LC3 to redistribute from the nucleus to the cytosol within less than 24 h. WebAs a result of its deacetylation, LC3 activation occurs, which controls the main steps of the autophagy, and during this process interacts and produces the degradation of the protein p62 [122]. In ...
WebAug 3, 2024 · K39 deacetylation also enhances the interaction of ATG4B with pro-LC3, which promotes LC3-II formation. Furthermore, an in vivo experiment using Sirt2 knockout mice also confirmed that SIRT2 … WebApr 12, 2024 · In PD, resveratrol decreases apoptosis by inhibiting NF-κB and degrading α-syn via deacetylation of LC3 [137,138,139,140]. Additionally, a recent study showed that SIRT1 could promote mitochondrial biogenesis by activating peroxisome proliferator-activated receptor-gamma coactivator 1 (PGC-1) [ 141 ] ( Figure 4 ).

WebOct 16, 2024 · We used LC3 mutants with arginine and glutamine replacements at lysine residues to show that deacetylation of LC3 at K49 and K51 by Sirt1 shifts LC3 distribution from the nucleus into the cytosol, where it is able to undergo lipidation at pre-autophagic membranes. Live cell imaging with GFP-tagged LC3 in L6 myocytes indicated that the …
WebFeb 5, 2015 · Deacetylation of LC3 at K49 and K51 by Sirt1 allows LC3 to interact with the nuclear protein DOR and return to the cytoplasm with DOR, where it is able to bind Atg7 and other autophagy factors and undergo phosphatidylethanolamine conjugation to preautophagic membranes.
WebMay 31, 2024 · In general, BmP300-mediated acetylation sequesters the components of BmAtg8-PE ubiquitin-like system in the nucleus, thus leading to the autophagy inhibition.
