Src homology (SH) 3 domains are small modules found in a diverse array of proteins. The presence of an SH3 domain confers upon its resident protein the ability to interact with specific proline-rich sequences in protein binding partners. A major focus of research has highlighted a role for SH3 domain-mediated interactions in the regulation of signal transduction events. However, more recent data has suggested an important function for SH3 domains in vesicular trafficking. This review will focus on this newly emerging role with a particular emphasis on the molecular components involved in synaptic vesicle endocytosis and the regulatory role of SH3 domain-mediated protein-protein interactions in this process.
