Caltech Researcher Sheds Light on M.O. of Unusual RNA Molecules (image) California Institute of Technology Share Print E-Mail Caption The Xist lncRNA (red) recruits proteins responsible for modifying chromatin architecture (green) across the X-chromosome. Xist and its associated proteins coat the entire X-chromosome, forming a distinctive compartment in the nucleus (blue). A new study sheds light on how Xist identifies its target locations and can spread across the chromosome, bringing genes together into these compartments.
