Sequence is from hamster polyoma virus middle T inclusive of Tyr324. This 11-residue phosphopeptide activates Src family members by binding with high affinity (Kd=3-6 nM for Src SH2) to their SH2 domains. The crystal structures of this peptide complexed to Src and Lck SH2 domains have been determined. Product Specification Sequence:Glu-Pro-Gln-pTyr-Glu-Glu-Ile-Pro-Ile-Tyr-Leu MW:1473.7 Purity:>98% Appearance:Lyophilized solid. Solubility:Soluble in Water. Long Term Storage:-20°C
