"Protein phosphorylation is an essential post-translational modification that modulates cell-cell communication. Substrate phosphorylation by protein kinases controls intracellular signal transduction pathways that mediate cell proliferation, migration, differentiation, and meta…
Protein kinases are fascinating enzymes that maintain the proper function of nearly every task performed by the cells of the human body. By extracting a phosphate from the energy molecule ATP and linking it to another protein, protein kinases alter the structure and ultimate fun…
The phosphatidylinositol polyphosphates play a fundamental role in intracellular signalling. Of particular importance is phosphatidylinositol 3,4,5-trisphosphate [PtdIns(3,4,5)P₃], which acts by recruiting effector proteins to the cell membrane. PtdIns(3,4,5)P₃ interacts with it…
PI3K has become a very intense area of research, with over 2000 publications on PI3K in PubMed for 2009 alone. The expectations for a therapeutic impact of intervention with PI3K activity are high, and progress in the clinical arena is being monitored by many. However, targeted …
