More than 700 genes control thousands of pathways in charge of the very life of each cell : the KINASE pathways. Kinases are enzymes that add phosphate ("phosphorylate") to protéins, and thus activate them and trigger a cascade of reactions.
Among these pathways 2 are very well known, and addressed by medicines
Many other Protein kinases exist. Their inhibitors play or could play a therapeutic role, in cancers, transplantation, inflammatory and neuro-degenerative diseases
