Antonin Morillon is director of research at CNRS and group leader of the ncRNA, epigenetics and genome fluidity team at Institut Curie. He is an ERC starting grant laureate and member of Young EMBO investigator program. His interests are to understand the epigenetic functions of long non-coding (lnc)RNAs in eukaryotes, especially those antisense to genes. Using RNA-seq technology, his team defined a novel class of cryptic lncRNA in yeast, termed XUTs with a regulatory function on gene expression that might be conserved throughout the eukaryotic kingdom and might have a role on genomic instability. The activity of the team is mostly dedicated to yeast genetics but also to genomics in human cancer cells.
