The mutation underlying myotonic dystrophy is the expansion of polymorphic CTG repeat in the 3'-noncoding region of the myotonin protein kinase (MtPK) gene mapping to chromosome 19q13.3. A full-length cDNA of human MtPK was cloned and expressed in COS-1 cells. We purified native full-length MtPK from rat skeletal muscle. This 70 kDa MtPK is localized in sarcoplasmic reticulum fraction, whereas the previously...
