Abstract
Two actin-binding sites have been identified on human dystrophin by proton NMR spectroscopy of synthetic peptides corresponding to defined regions of the polypeptide sequence. These are Actin-Binding Site 1 (ABS1) located at residues 17–26 and Actin-Binding Site 2 (ABS2) in the region of residues 128–156. Using defined fragments of the actin amino acid sequence, ABS1 has been shown to bind to actin in the region represented by residues 83–117 and ABS2 to the C-terminal region represented by residues 350–375. These dystrophin-binding sites lie on the exposed domain in the actin filamentKeywords
