Src homology 3 (SH3) domains, which are found in many proteins involved in intracellular signal transduction, mediate specific protein-protein interactions. The three-dimensional structure of the SH3 domain in the p85 subunit of the phosphatidylinositol 3-kinase (PI3K) has been determined by multidimensional NMR methods ...
