WebIndividual RTK-mediated signaling cascades can be targeted at several levels to develop anti-cancer therapeutic agents that inhibit the signaling pathways via disruption of interactions between RTKs and their ligands, dimerization and phosphorylation of RTKs, and activation of downstream elements. 2,4 For monoclonal antibody-based therapeutics ... WebReceptor tyrosine kinases (RTKs) are a conserved superfamily of transmembrane growth factor receptors that drive numerous cellular processes during development and in the adult. Upon activation, multiple adaptors and signaling effector proteins are recruited to binding site motifs located within the intracellular domain of the RTK.
