'''STRUCTURAL BASIS FOR SPECIFIC RECOGNITION OF AN RXXK-CONTAINING SLP-76 PEPTIDE BY THE GADS C-TERMINAL SH3 DOMAIN'''<br /> | '''STRUCTURAL BASIS FOR SPECIFIC RECOGNITION OF AN RXXK-CONTAINING SLP-76 PEPTIDE BY THE GADS C-TERMINAL SH3 DOMAIN'''<br /> | ||
==Overview== | |||
The SH3 domain, which normally recognizes proline-rich sequences, has the potential to bind motifs with an RxxK consensus. To explore this novel specificity, we have determined the solution structure of the Gads T cell adaptor C-terminal SH3 domain in complex with an RSTK-containing peptide, representing its physiological binding site on the SLP-76 docking protein. The SLP-76 peptide engages four distinct binding pockets on the surface of the Gads SH3 domain and upon binding adopts a unique structure characterized by a right-handed 3(10) helix at the RSTK locus, in contrast to the left-handed polyproline type II helix formed by canonical proline-rich SH3 ligands. The structure, and supporting mutagenesis and peptide binding data, reveal a novel mode of ligand recognition by SH3 domains. | |||
