Research Abstract

We characterized the nuclear localization of AUUCU and CCUG RNA foci associated with spinocerebellar ataxia type 10 (SCA10) and myotonic dystrophy type 2 (DM2), and detected the AUUCU and/or CCUG RNA-binding proteins. These are considered to lead to the elucidation of RNA-disease mechanism of both diseases in the future. Moreover, we identified a new subtype of spinocerebellar ataxia type 36 (SCA36) caused by large non-coding GGCCTG expansions.
