Gene Information

human ... MBNL1(4154)

General description

Muscleblind 1 (MBNL1) is a member of the muscleblind family. MBNL1in 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

Histidine-tagged recombinant protein corresponding to human MBNL1.
