Phosphorylation means addition of a phosphate group usually from an ATP molecule. The series of events which trigger a signalling event involving a series of kinases which ultimately phosphorylate a target protein and bring about a physiological change is called as a kinase cascade.Click to see full answer. Regarding this, what is meant by a protein kinase cascade?Intracellular protein kinase cascade. Definition: A series of reactions in which a signal is passed on to downstream proteins within the cell by sequential protein phosphorylation and activation of the cascade components.Subsequently, question is, how does a protein kinase cascade work what does it do to the original signal? Kinases are enzymes responsible for this phosphorylation. Phosphorylation reactions often occur in series, or cascades, in which one kinase activates the next. These cascades serve to amplify the original signal, but also improving the signal (less noise) and allowing for cross talk between different pathways. In respect to this, what is the function of a kinase? In biochemistry, a kinase is an enzyme that catalyzes the transfer of phosphate groups from high-energy, phosphate-donating molecules to specific substrates. This process is known as phosphorylation, where the substrate gains a phosphate group and the high-energy ATP molecule donates a phosphate group.What is MAP kinase cascade?The mitogen-activated protein kinase (MAPK) cascades are evolutionary conserved, intracellular signal transduction pathways that respond to various extracellular stimuli and control a large number of fundamental cellular processes including growth, proliferation, differentiation, motility, stress response, survival and
