RRR diagrams representing molecules, species, and complexes.
A. EGFR molecule with 4 sites l, r, Y1068 and Y1148, with the last two being in two possible states each - unphosphorylated “u” and phosphorylated “p”. B. An EGFR species represented by an EGFR molecule with sites Y1068 and Y1148 both in the unphosphorylated (“Y”) state. C. A species consisting of an EGFR molecule connected to a Grb2 molecule via a bond between the phosphorylated (“p”) state of the Y1068 site on EGFR and the SH2 site on Grb2.
