Among a number of various molecules, Receptor Tyrosine Kinases (RTKs) play a critical role in transducing signals through a range of signaling pathways. All RTKs consists of an extracellular ligand binding region, a single transmembrane helix and a cytoplasmic region (the tyrosine kinase domain). Prior to ligand stimulation most RTKs present as a monomer on the surface of cells. Ligand binding to the extracellular domain induces dimerization. Dimerization of RTKs leads to a…
