Upon cellular reprogramming, the activity of polycomb repressive complex 2 (PRC2), together with histone demethylases, is essential for the suppression of cell lineage-specific gene expression programs, for resetting of epigenetic memory and for the reacquisition of pluripotency. PRC2 requires interaction with RNAs for the correct protein complex assembly and recruitment on chromatin. Moreover, PRC2 components can be found in different cell compartments and their intracellular dynamics is part of their functional activity. Several loss-of-function studies revealed that many lncRNAs expressed upon reprogramming are essential for the silencing of lineage-specific genes and the function of chromatin modifiers. Compartment-specific UV-RIP technique is a method that will help understanding which is the nature of those interactions, with no interference from indirect interactions typical of methods involving the use of chemical cross-linkers or performed in native conditions with non-stringent buffers. This technique will shed lights on the specificity of lncRNA interaction and PRC2 stability/activity on chromatin and whether PRC2-lncRNA interaction occurs in specific cell compartments.
