Noncoding RNA and Polycomb recruitment
RNA 2013; 19: 429-442
A plethora of noncoding (nc) RNAs have been revealed through the application of high-throughput analysis of the transcriptome, and this has led to an intensive search for possible biological functions attributable to these transcripts. A major category of functional ncRNAs that has emerged concerns those that are implicated in coordinate gene silencing, either in cis or in trans. Xist and other ncRNAs have been shown to bind to PRC2, a repressive chromatin modifying complex. Silencing has been proposed to involve direct interaction between PRC2 proteins and the different ncRNAs. This review discusses the evidence for and against this hypothesis, in the process highlighting alternative models and discussing experiments that in the future will help to resolve existing discrepancies.
