A protein kinase is a crucial enzyme that acts like a molecular switch, adding a phosphate group from ATP to specific amino acids (serine, threonine, or tyrosine) on other proteins, a process called phosphorylation, which changes the target protein’s activity, function, or location. These enzymes regulate nearly all cellular processes, including cell growth, metabolism, division, and signaling, making them essential for life and often implicated in diseases like cancer and diabetes when they malfunction

  mTOR (Mechanistic Target of Rapamycin) is a crucial Protein Kinase that acts as a central hub for sensing nutrients, energy, and growth signals to control fundamental cell functions like growth, metabolism, protein synthesis, and proliferation, playing key roles in health, aging, and diseases like cancer and diabetes
