Phosphorylated receptor tyrosine kinase dimer

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… Web(A) intracellular receptor (B) G protein-coupled receptor (C) phosphorylated receptor tyrosine kinase dimer (D) ligand-gated ion channel Question Binding of a signaling molecule to which type of receptor leads directly to a change in the distribution of substances on opposite sides of the membrane?
