Phosphorylated receptor tyrosine kinase dimer
WebOn the cytoplasmic side, the two tyrosine kinase domains (N- and C-lobes colored dark and light, respectively) form an asymmetric dimer, with the C-lobe of one kinase domain (purple) interacting with the N-lobe of the other kinase domain (cyan). This interaction activates the second kinase domain (cyan) . The yellow spheres represent ... WebTyrosine Phosphotyrosine When a growth factor binds to the extracellular domain of a RTK, its dimerization is triggered with other adjacent RTKs. Dimerization leads to a rapid activation of the protein's cytoplasmic kinase domains, the first substrate for these domains being the receptor itself.
