生物活性

EPQpYEEIPIYL, a phosphopeptide, is a Src homology 2 (SH2) domain ligand. EPQpYEEIPIYL activates Src family members (e.g. Lck, Hck, Fyn) by binding to SH2 domains[1][2].

体外研究
(In Vitro)

The hmT-derived phosphopeptide, pY324, which has the sequence EPQpYEEIPIYL, shows the highest affinity binding to GST fusion proteins of the Lck SH2 domain (5-fold higher than Lck’s affinity-for the Lck tail phosphopeptide) and the Src SH2 domain (44-fold higher than Src’s affinity for the Src tail phosphopeptide)[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
