NettetFollowing the binding of an extracellular signal molecule, receptor tyrosine kinases (RTKs) are activated by dimerization, which allows: each polypeptide chain to cross-phosphorylate the other chain in the dimer on specific tyrosines in its cytoplasmic tail. The phosphorylated tyrosines on activated RTKs: Nettet1. mar. 2014 · Receptor tyrosine kinases (RTKs) and their cellular signaling pathways play important roles in normal development and homeostasis. Aberrations in their activation or signaling leads to many pathologies, especially cancers, motivating the development of a variety of drugs that block RTK signaling that have been successfully applied for the …
