Peptides specific for the first crk-sh3 domain

摘要

The present invention relates to regulation and control of cellular processes by SH3-domain binding proteins and peptides. In particular, the invention provides a consensus sequence of a peptide that shows high specificity and affinity for the first SH3 domain of cellular Crk. In specific examples, a number of peptides that contain the consensus are shown to bind c-Crk specifically. The molecular basis for this specificity is examined by crystallography.
