Anti-CUGBP1 Antibody, clone 3B1

50kDa

Myotonic dystrophy (MD) is an autosomal dominant neuromuscular disease that is associated with a (CTG)n repeat expansion in the 3′-untranslated region of the myotonin protein kinase (Mt-PK) gene. A (CUG)n oligonucleotides triplet repeat pre-mRNA/mRNA binding protein may play an important role in DM pathogenesis. HeLa cell protein, CUG-BP1, has been purified based upon its ability to bind specifically to (CUG)8 oligonucleotides in vitro. CUG-BP1 is 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/photocrosslinking studies demonstrate that CUG-BP/hNab50 binds to RNAs containing the Mt-PK 3′-UTR.
