Structural highlights
Function
SNTA1_MOUSE Adapter protein that binds to and probably organizes the subcellular localization of a variety of membrane proteins. May link various receptors to the actin cytoskeleton and the extracellular matrix via the dystrophin glycoprotein complex. Plays an important role in synapse formation and in the organization of UTRN and acetylcholine receptors at the neuromuscular synapse. Binds to phosphatidylinositol 4,5-bisphosphate.

Publication Abstract from PubMed
Syntrophins are modular proteins belonging to the dystrophin associated glycoprotein complex and are thought to be involved in the regulation of the muscular system. Screening of peptide libraries revealed selectivity of the synotrophin PDZ domain toward the motif R/K/Q-E-S/T-X-V-COO- found to be highly conserved in the alpha-subunit C-terminus of vertebrate voltage gated sodium channels (VGSCs). The solution structure of the domain in complex with the peptide G-V-K-E-S-L-V shows specific interactions between the conserved residues in the peptide and syntrophin-characteristic residues in the domain. We propose that syntrophins localize VGSCs to the dystrophin network through its PDZ domain.
