PI3K Pathway

Phosphoinositide 3-Kinase enzyme It is a signal transduction system that connects oncogenes and multiple receptor classes to many cellular functions such as cell survival, proliferation and differentiation. The key enzyme family in this pathway is PI3Ks (Phosphoinositide 3-Kinases) which transducer signals from various growth factors and cytokines into intracellular messages by generating phospholipids. These phospholipids activate the serine- threonine...
