The subject disclosure relates to substantially pure nucleic acid sequences encoding at least a portion of a dystrophin-associated protein. Deoxyribonucleic acid can be expressed in a DNA expression construct. Protein produced in this manner can be used for a variety of purposes including immunization to produce antibodies. Such DNA expression constructs, and the protein encoded by same, are useful in therapeutic methods to complement a genetic defect which results in muscular dystrophy.
