Research Area

Transcription is a key step for gene expression regulation, which in turn globally programs or reprograms the cells. In prokaryotic cells, two-component system (TCS), including histidine kinase (SK) and response regulator (RR), is responsible for stimuli induced transcription. Our lab uses VicRK, one of streptococci TCS as a model system to understand how the intra/extracellular signals regulate the transcription of bacteria. In eukaryote cells, transcription factors as well as cofactors are centered on the specific enhancer regions of genes to form high-order regulatory assemblies. The most, if not all, of these cofactors are histone modification enzymes that convey a variety of upstream signals to epigenetic marks. Our lab is taking a structural and functional approach to understand molecular mechanisms of the epigenetic modifications and transcriptional regulation, in particular the histone acetylation by p300, CBP and PCAF.
