CELF1 and myotonic dystrophy type 1: Additionally, the term “phosphoprotein” is interesting since DM1 pathogenesis is associated with hyperphosphorylation of CUGBP1 protein [52,53], and studies have shown that the utilization of small molecule kinase inhibitors led to the alleviation of some of the molecular symptoms of DM1 including downregulation of CUGBP1 and correction of some of the mis-spliced genes [100,101].
