Genomic views of protein-RNA interactions and splicing regulation

Posttranscriptional regulation plays a critical role in development and tissue identity. The information in the RNA sequence and how it is read and interpreted by RNA-binding proteins is commonly referred to as the ‘ribonucleoprotein (RNP) code’. Cracking this code and understanding the underlying regulatory networks remain long-standing goals of RNA biologists.

To decipher the RNP code, I previously developed iCLIP, a technique that provides genome-wide maps of protein-RNA interactions with single-nucleotide resolution. Our group uses iCLIP to address the following key questions: What is the organisation of cis-regulatory elements? How do proteins act together in RNP assembly? How do RNPs control gene regulation in early development? By cracking the RNP code, we aim to better understand human biology and disease.
