WebA phosphorylation cascade is organised from many signalling proteins controlled by kinases. A protein kinase is activated by phosphorylation which in turn phosphorylates the next protein kinase in a sequence and so on. As the signal is carried onwards it is amplified and sometimes can spread to other signalling pathways [1] . WebOne of the most common intracellular signaling pathways triggered by RTKs is known as the mitogen-activated protein (MAP) kinase cascade, because it involves three serine-threonine kinases.The ...
