Kondo Research Unit
Research Areas
| Architecture of multi-cellular organisms are closely linked with their functions. During embryogenesis, transcriptions of genes are regulated temporally and spatially restricted manner to construct proper body structures. Within a brain, complex patterning is also required to achieve correct construction of functional architecture. Whereas many lines of results are accumulated for enhancer and promoter activities, it is not sufficient to explain how correct expressions of multiple genes within a genome can be accomplished. Although it is recognized that interaction of these elements has to be organized, it remains unclear the way these cis-regulatory elements co-operate and interact within a genome. Our primary aim is to investigate the influences from chromosomal environment and nuclear structure on transcription. |  Unit Leader Takashi KONDO (Ph.D.)  |
