Abstract

Three sequence motifs at the N-terminus of dystrophin have previously been proposed to be important for binding to actin. By analyzing a series of purified bacterial fusion proteins deleted for each of these sites we have demonstrated that none of the three are critical for dystrophin-actin interactions. Instead, our data suggest that sequences in the N-terminal 90 amino acids of dystrophin, excluding a conserved KTFT motif, contain the major site for interaction with actin.
