Which of the following is not true about phosphorylated tyrosines residues, or phosphotyrosines?

Phosphotyrosines are docking sites for proteins with SH2 domains.

Autophosphorylation is the process that facilitates secondary-receptor tyrosine residue phosphorylation.

Receptor tyrosine kinases contain intracellular tyrosine residues that become phosphorylated upon receptor activation.

Ras-GEF adaptor proteins bind to phosphotyrosine residues on the EGF receptor (EGFR).

Tyrosine residues are phosphorylated by tyrosine kinase domains on the same receptor.
