C-SRC SH3 DOMAIN COMPLEXED WITH LIGAND VSL12
Overview
Two dodecapeptides belonging to distinct classes of Src homology 3 (SH3), ligands and selected from biased phage display libraries were used to, investigate interactions between a specificity pocket in the Src SH3, domain and ligant residues flanking the proline-rich core. The solution, structures of c-Src SH3 complexed with these peptides were solved by NMR., In addition to proline-rich, polyproline type II helix-forming core, the, class I and II ligands each possesses a flanking sequence that occupies a, large pocket between the RT and n-Src loops of the SH3 domain. Structural, and mutational analyses illustrate how the two classes of SH3 ligands, exploit a specificity pocket on the receptor differently to increase, binding affinity and specificity.
