ProteomicsJurkat 2D-LC-MS/MS - Enzyme Kinetics for Complex System Enables Accurate Determination of Specificity Constants of Numerous Substrates in a Mixture by Proteomics Platform
We found the ratio of substrate depletion is independent of other coexisted substrates under specific condition with the application of self-developed iteration approach. The further established simplified model was applied to determine the catalytic efficiencies of peptide substrates of a protease ...

ProteomicsA sensitive and cost-effective approach for tyrosine phosphoproteome analysis based on SH2 superbinder
Albeit much less abundant than Ser/Thr phosphorylation (pSer/pThr), Tyr phosphorylation (pTyr) is considered a hallmark in cellular signal transduction. However, its analysis remains a challenge. The conventional immunopurification (IP) approach using antibodies pan-specific to pTyr sites is known t...

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...

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. ...
