ResumoThe 70.8 kDa protein, Dp71, is the major Duchenne muscular dystrophy (DMD) gene product in many nonmuscle tissues including the brain. Dp71 shares most of the C‐terminal and cysteine‐rich domains with the dystrophins but lacks the entire large rod shaped domain of spectrin‐like repeats, and the N‐terminal actin‐binding domain. The function of Dp71 is unknown. Using subcellular fractionation and immunostaining we show that Dp71 is associated with the plasma membrane. Dp71 is also associated with the plasma membrane in mdx myogenic cells transfected with a vector expressing Dp71.
