Abstract：
Proteins in the cell are subjected to numerous post-translationalmodifications (PTM). PTMs not only greatly increase the size of the proteome,they also enrich protein function and enable dynamic control of essentialcellular processes such as proliferation, differentiation, and apoptosis. Weare interested in understanding the mechanism of signal transduction mediatedby protein phosphorylation and methylation in cells under normal orpathological conditions. A major focus of my lab is to identify novel tyrosinephosphorylation and lysine methylation sites and to characterize their functionsin tumorigenesis and drug resistance. By combining proteomic techniques such asmass spectrometry and peptide/protein microarrays with conventionalbiochemical, molecular, and cellular approaches, we hope to uncover novel PTMevents in an effective and systematic manner, generate new insights intodisease mechanism, and develop innovative strategies for the accurate diagnosisand precise treatment of complex human diseases such as cancer.
