#XL - T Zoology

The SH2 domain binds strongly to short target peptides containing a critical four-residue core sequence:: 

phosphotyrosine–glutamic acid–glutamic acid–isoleucine

#XL - T Zoology

Binding resembles the insertion of a two-pronged “plug” the phosphotyrosine and isoleucine side chains

of the peptide into a two-pronged “socket” in the SH2 domain.
