This proposed relationship between MBNL and miRNAs might explain why colocalization of MBNL with RNA foci does not necessarily trigger DM1 downstream events [50] and why MBNL1 apparently binds to other types of repeats even better than CTG repeats [51]; in both cases, miRNA-binding to CTG repeats might mediate this interaction. This evidence concerns the gene MBNL1 and myotonic dystrophy type 1.
