When signaling molecules bind to RTKs, they cause neighboring RTKs to associate with each other, forming cross-linked dimers. Cross-linking activates the tyrosine kinase activity in these RTKs through phosphorylation specifically, each RTK in the dimer phosphorylates multiple tyrosines on the other RTK.
