'''Tuba''' or '''dynamin-binding protein''' is a scaffold protein found in brain synapses which brings together dynamin and actin regulatory proteins. The N-terminal SH3 domains bind dynamin and the C-terminal SH3 domain binds actin regulatory proteins<ref>PMID:14506234</ref>. | |||

Tuba contains 6 SH3 domains. The C-terminal 6th domain binds proline-rich regions of human actin regulating proteins such as N-WASP and Mena. The peptide forms a polyproline type II helix. The interactions of Tuba with the peptide is via SH3-conserved residues<ref>PMID:24332715</ref>. | Tuba contains 6 SH3 domains.
