GRB2 phosphorylated on Y209 is inactive. 2 / 2

"More recently, however, tyrosine phosphorylation of Grb2 in BCR-ABL-transformed cells on residues Tyr7, Tyr37, Tyr52, and Tyr209 in the SH3 domains has been reported and shown to negatively regulate the Ras/MAPK pathway."

"Phosphorylation of grb2 by bcr/abl or egf receptor reduced its sh3-dependent binding to sos in vivo, but not its sh2-dependent binding to bcr/abl. Tyr209 within the c-terminal sh3 domain of grb2 was identified as one of the tyrosine phosphorylation sites"
