ProteomicsATR-dependent phosphorylation of the histone acetyltransferase HBO1 suppresses chromatin binding and promotes replication stress responses.
This dataset contains label-free immunoprecipitation mass spectrometry (IP-MS) data to identify interacting partners of target proteins in human cell lines. Two sample groups (OMM2.3-input, OMM2.3-IP) were generated via co-immunoprecipitation with anti-HBO1 antibody. All LC-MS/MS proteomic detection...

ProteomicsMS data of phosphorylation sites of IRF4/TCF3/TCF4 by p38α
To identify putative phosphorylation sites on TCF3 (E47), TCF4, and IRF4, in vitro kinase assays were performed using recombinant MKK6E (a p38α activator) and p38α as kinases, and TCF3(E47), TCF4, or IRF4 proteins as substrates, the phosphorylation sites were analyzed by mass spectrometry (MS).

ProteomicsOligodendrocyte precursor cell-specific blocking of low glucose-induced activation of AMPK ensures myelination and remyelination
In this study, we screening the main types of cerebral cortex cells for glucose sensing and have find that AMPK is not activated in OPCs. We further discover that aldolase C (ALDOC) is acetylated at K14 in OPCs. Expression of ALDOC-K14R, with the acetylation lysine residues changed to arginine, rend...

ProteomicsLow-dose metformin targets the lysosome-AMPK pathway through PEN2
Metformin is the most prescribed anti-diabetic medicine, and has also been shown to have other various benefits, such as anti-aging and anti-cancer effects. For clinical doses of metformin, it is known that AMPK plays a major role; however, the direct molecular target of metformin remains unclear. H...

ProteomicsLithocholic acid targets TULP3-Sirtuins to deacetylate v-ATPase and activate AMPK
Lithocholic acid (LCA), accumulated in mammals during calorie restriction (CR), can activate AMP-activated protein kinase (AMPK) and slow down ageing1. However, how LCA is signalled to activate AMPK and elicit the biological effects is unclear. Here, we show that LCA can enhance the activity of sirt...

ProteomicsThe aldolase inhibitor aldometanib mimics glucose starvation to activate lysosomal AMPK
The activity of 5’-adenosine monophosphate-activated protein kinase (AMPK) is inversely correlated with the cellular availability of glucose. When glucose levels are low, the glycolytic enzyme aldolase is not bound to fructose-1,6-bisphosphate (FBP) and, instead, signals to activate lysosomal AMPK. ...
