RIKEN Center for Integrative Medical Sciences Laboratory for Functional Non-coding Genomics
Team Leader: Yuka Iwasaki (Ph.D.)
One of the significant achievements of recent transcriptome research is elucidating the importance of "non-coding genomic regions" that do not encode proteins. In diverse eukaryotes, non-coding genomic regions occupy huge portions of the genome. They include non-coding RNAs that do not code for proteins but perform various functions as RNAs and transposons that have the property of transposing or jumping around the genome. We aim to understand diseases, including developmental disorders, from new perspectives by clarifying and regulating the functional mechanisms of non-coding genomic regions.
