Research highlight

We are analyzing biological roles of noncoding RNAs (ncRNAs) in a wide range of cellular reactions, such as pre-mRNA splicing, nuclear structure formation, chromatin remodeling and genome stability, using fission yeast and cultured mammalian cells. NcRNAs are defined as RNAs with no significant protein-coding capacity. We have recently revealed that ncRNAs transcribed from the centromere regions have essential roles in chromosome segregation. A new paradigm of “ncRNA regulation in chromosome segregation” is now emerging.

In addition, we are trying to breed novel fission yeast strains suitable for brewing rice (or sweet potato) shochu, a traditional Japanese distilled sprit, which is generally brewed by budding yeast Saccharomyces cerevisiae.
