• PubMed Abstract: 
  

The three-dimensional structure of the N-terminal SH3 domain (residues 583-660) of murine Vav, which contains a tetra-proline sequence (Pro 607-Pro 610), was determined by NMR. The solution structure of the SH3 domain shows a typical SH3 fold, but it exists in two conformations due to cis-trans isomerization at the Gly614-Pro615 bond. The NMR structure of the P615G mutant, where Pro615 is replaced by glycine, reveals that the tetra-proline region is inserted into the RT-loop and binds to its own SH3 structure. The C-terminal SH3 domain of Grb2 specifically binds to the trans form of the N-terminal SH3 domain of Vav. The surface of Vav N-terminal SH3 which binds to Grb2 C-terminal SH3 was elucidated by chemical shift mapping experiments using NMR. The surface does not involve the tetra-proline region but involves the region comprising the n-src loop, the N-terminal and the C-terminal regions. This surface is located opposite to the tetra-proline containing region, consistent with that of our previous mutagenesis studies.
