The fission yeast is shown to have a mechanism to prevent small RNAs from inducing heterochromatin and epigenetic gene silencing; this protective model involves the highly conserved Paf1 complex, which is known to promote transcription and processing of pre-mRNA, and protects protein-coding genes from unwanted silencing by spurious transcripts.
