Silent decision: HP1 protein escorts heterochromatic RNAs to their destiny.


Heterochromatin is classically perceived to be refractory to transcription because of its compact structure. However, Keller et al (2012) now demonstrated that heterochromatic transcripts can accumulate even when heterochromatin is normally packaged. By tracking down the fate of these heterochromatic RNAs, they revealed a new post-transcriptional mechanism… (More)
