In silico analyses of dystrophin Dp40 cellular distribution, nuclear export signals and structure modeling.

Dystrophin Dp40 is the shortest protein encoded by the DMD (Duchenne muscular dystrophy) gene. This protein is unique since it lacks the C-terminal end of dystrophins. In this data article, we describe the subcellular localization, nuclear export signals and the three-dimensional structure modeling of putative Dp40 proteins using bioinformatics tools.

EF-hand domains are involved in the differential cellular distribution of dystrophin Dp40.

Dp40 is the shortest DMD gene product that has been reported to date. It is encoded by exons 63-70, a region required for a β-dystroglycan interaction. Its expression has been identified in rat, mouse, and human; however, its function remains unknown.
