AB  - 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.
