Target Information

Myotonic dystrophy (MD) is an autosomal dominant neuromuscular disease associated with a (CTG)n repeat expansion in the 3′-untranslated region of the myotonin protein kinase (Mt-PK) gene. A (CUG)n oligonucleotide triplet repeat pre-mRNA/mRNA binding protein may play an important role in DM pathogenesis.

HeLa cell protein CUG-BP1 binds specifically to (CUG)8 oligonucleotides in vitro and represents the major (CUG)8 binding activity in normal cells. CUG-BP1 has been identified as isoforms of a novel heterogeneous nuclear ribonucleoprotein (hnRNP), hNab50. The CUG-BP/hNab50 protein is localized predominantly in the nucleus and is associated with polyadenylated RNAs in vivo.

In vitro RNA-binding and photocrosslinking studies show that CUG-BP/hNab50 binds to RNAs containing the Mt-PK 3′-UTR. The (CUG)n repeat region in Mt-PK mRNA is a binding site for CUG-BP/hNab50 in vivo, and triplet repeat expansion leads to sequestration of this hnRNP on mutant Mt-PK transcripts.
