Background CUG-binding protein 1 (CUG-BP1) was the first discovered member of the CUG-BP1 and ETR-3-like factors (CELF) family. All CELF proteins possess the same domain structure comprising 3 RNA recognition motifs (RRMs) and a divergent hinge region of 60&ndash;90 residues between RRM2 and RRM3. CUG-BP1 performs various functions in posttranscriptional gene regulation, including alternative splicing, translation, and deadenylation. It has been reported that CUG-BP1 plays a role in the pathogenesis of the trinucleotide expansion disease, namely, myotonic dystrophy (DM1), in that it is associated with (CTG)<em>n</em> repeat expansion in the 3&prime; UTR of myotonin protein kinase (Mt-PK) gene. The (CUG)<em>n</em> repeat region in Mt-PK mRNA is the binding site for CUG-BP1, and the triplet repeat expansion sequesters CUG-BP1 on mutant Mt-PK mRNAs. Recent studies have demonstrated that CUG-BP1 has stronger affinity toward UG repeats than CUG repeats. Since UG repeats are enriched in short-lived transcripts, CUG-BP1 was suggested to be a mediator of UG-motifs-dependent mRNA decay.
