General description

Muscleblind 1 (MBNL1) is a member of the muscleblind family. MBNL1 is involved in pre-mRNA alternative splicing and acts as either splicing activator or repressor on specific pre-mRNA targets. This protein contains four C3H1-type zinc fingers and binds to expanded CUG repeat RNA. High expression of MBNL1 has been observed in cardiac and skeletal muscle as well as in differentiating myoblasts. MBNL1 is known to be involved in the pathogenesis of dystrophia myotonica type 1 (DM1). For those afflicted with this muscular disorder, MBNL1 is sequestered by DMPK RNAs that contain CUG triplet repeat expansions.

Immunogen

Full length recombinant protein corresponding to human MBNL1.

RNA repeat expansions are responsible for more than 30 incurable diseases. Among them is myotonic dystrophy type 1 (DM1), the most common form of adult on-set muscular dystrophy. DM1 is caused by an r(CUG) repeat expansion [r(CUG)exp] located in the

Myotonic dystrophy type 2 (DM2) is a genetically defined disease caused by a toxic expanded repeat of r(CCUG) [r(CCUG)exp], harbored in intron 1 of CCHC-type zinc-finger nucleic acid binding protein (CNBP) pre-mRNA. This r(CCUG)exp causes toxicity via a gain-of-function mechanism

Myotonic dystrophy Type 1 (DM1) is a rare genetic disease caused by the expansion of CTG trinucleotide repeats ((CTG)exp) in the 3' untranslated region of the DMPK gene. The repeat transcripts sequester the RNA binding protein Muscleblind-like protein 1 (MBNL1)

Many diseases are caused by toxic RNA repeats. Herein, we designed a lead small molecule that binds the structure of the r(CUG) repeat expansion [r(CUG)exp] that causes myotonic dystrophy type 1 (DM1) and Fuchs endothelial corneal dystrophy (FECD) and rescues
