Research Interests

1. Study the molecular and structural mechanisms of the epigenetic regulation on gene expression.
2. Understand the functional mechanisms of non-coding RNAs using the methods of structural biology.

Over the past decade, long non-coding RNAs (lncRNAs) have emerged as an important class of the genomic pervasive transcripts that are involved in a variety of biological functions in many model systems. Bioinformatic and high-throughput loss of function analyses suggest that lncRNAs add a critical layer of regulation on the gene expressions of diverse biological processes, ranging from stem cell pluripotency to tumorigenesis. Through the knowledge of the small number of well characterized lncRNAs to date, it’s realized that lncRNAs usually exist in the form of ribonucleoprotein complex (RNP), in which lncRNAs and the associated protein factors cooperate with each other to regulate their target genes. Chromatin modifiers and transcription factors are among the most common lncRNA-associated factors. Current studies on lncRNAs are primarily limited to the functional analyses of the entire RNP complexes. It remains elusive about the functional protein-RNA domains involved in the formation of lncRNPs as well as about how lncRNPs are assembled on their targets. Extensive biochemical and structural studies are required to address these questions. Our lab aims at understanding the coordinated functions of lncRNAs and their associated protein factors at the structural and mechanistic levels. Our current studies focus on several important lncRNAs that participate in embryogenesis and tumorigenesis.
