RNA-based Gene Regulation

RNA is an important focal point for the regulation of gene expression. Both protein-coding and noncoding RNAs are integral components of diverse regulatory pathways, and often act together with protein cofactors. Coding RNAs serve as templates for protein synthesis and are tightly regulated through control of RNA synthesis, processing, and degradation. Noncoding RNAs (ncRNAs) are a diverse group of non-translated transcripts with a wide variety of functions. For example, certain ncRNAs directly repress the transcription machinery. Some RNAs have even been shown to be bifunctional, having both coding and noncoding potential. The cellular activities of all types of RNA can be further fine-tuned through subcellular localization and RNA editing.

Our group aims to understand the molecular mechanisms by which RNA controls human gene regulation. We are particularly interested in understanding how ncRNAs regulate transcription, and how RNA activity can be regulated through post-transcriptional processes. We employ a variety of biochemical and structural methods, including X-ray crystallography and cryo-electron microscopy (cryo-EM). Cryo-EM has emerged as a particularly powerful tool for the determination of near-atomic structures while simultaneously providing insight into their dynamics. Through these studies, we work to unravel the regulatory networks that employ RNA as an intermediate.
