Protein binding motif

Protein binding motif is a short protein sequence motif that interacts with other proteins. A typical example of such motif are proline-rich sequences that are responsible for binding of SH3 domains.

Protein binding sequences may be locally unfolded, as in many endocytic proteins. For example, some EH domains (e.g. in Eps15 protein) contain at least 15 repeats of Asp-Pro-Phe tripeptide, which are responsible for interaction with multiple copies of the AP2 alpha appendage protein.
