Phosphoproteomics studies
Intracellular signal transduction is primarily mediated by the reversible phosphorylation of various signalling molecules by enzymes dubbed kinases. Kinases transfer phosphate groups from ATP to specific serine, threonine or tyrosine residues of target molecules. The resultant phosphorylated protein may have altered activity level, subcellular localization or tertiary structure. WebJul 11, 2024 · Phosphoproteomics data analysis involves two major steps. The first step includes the identification, phosphosite localization, and quantification of …
