CAV3 and Duchenne muscular dystrophy: In this study, the protein interaction map of this muscle-wasting condition was generated to gain a better knowledge of interactome profile of DMD.<h4>Materials & methods</h4>Applying Cytoscape and String Database, the protein-protein interaction network was constructed and the gene ontology of the constructed network was analyzed for biological process, molecular function, and cellular component annotations.<h4>Results</h4>Among 100 proteins related to DMD, dystrophin, utrophin, caveolin 3, and myogenic differentiation 1 play key roles in DMD network.
