WebFeb 19, 2024 · RTKs are activated through formation of inter-molecular dimerization in the presence of ligands, resulting in kinase activation and phosphorylation of the receptor C-terminal tail. b Schematic representation of potential gain-of-function mutations in the various subdomains of an RTK. WebReceptor tyrosine kinases (RTKs) are a group of membrane-bound receptors that play an important role in the normal function of cells. They act as signal transducers that mediate cell-to-cell communication by phosphorylating tyrosine residues on key intracellular substrate proteins.
WebThe phosphoinositide 3-kinase pathway is perhaps the most commonly activated signaling pathway in human cancer. This pathway thus presents both an opportunity and a challenge for cancer therapy. Even as inhibitors that choose PI3K isoforms and other leading nodes in the pathway including AKT and mTOR reach clinical trials, primary issues persist.
