Polycomb repressive complex 2 (PRC2) and its methylation of histone 3 at lysine 27 (H3K27me3) play a crucial role in epigenetic regulation of normal development and malignancy. Several factors regulate the recruitment of PRC2 and affects its chromatin modification function. Over the past years, emerging discoveries have portrayed the association of RNA (protein-coding and non-coding) with PRC2 as a critical factor in understanding PRC2 function. With PRC2 being a macromolecular complex of interest in development and diseases, further studies are needed to relate the rapidly evolving PRC2:RNA biology in that scenario. In this review, we summarize the current understanding of different modes of RNA binding by PRC2, and further discuss perspectives, key questions and therapeutic applications of PRC2 binding to RNAs.
