| The Wiskott Aldrich syndrome protein was identified as a protein that associated selectively with the SH 3 domains derived from c Src , p85alpha , phospholipase Cgamma 1 , and c Fgr . ^^^ Three peptides corresponding to potential Wiskott Aldrich syndrome protein SH 3 domain binding motifs were found to inhibit its association with c Src , Fgr , and phospholipase Cgamma 1 SH3 domains , but not the p85alpha SH 3 domain . ^^^ |
