Other information on the target : The muscleblind-like (MBNL) family of proteins, comprising MBNL1, MBNL2 and MBNL3, normally bind to YGC (Y stands for pyrimidine) RNA motifs and are diverted away from their normal RNA targets by the expanded CUG RNA repeats in DMPK transcripts.\r\nReduced MBNL function appears to be a key pathogenic event underlying the skeletal muscle alterations observed in DM1. Indeed, overexpression of MBNL1 rescues DM1-like skeletal muscle alterations in a mouse model of DM1. Furthermore, compounds or strategies aimed at reducing MBNL1 binding to expanded CUG repeats alleviate skeletal muscle dysfunctions in cell and animal models of DM1.
