Transcriptome studies reveal many noncoding transcripts overlapping 3’ gene termini. The function of these transcripts is unknown. Here we characterize transcription at the progesterone receptor (PR) locus and identify noncoding transcripts that overlap the 3’ end of the gene. Small RNAs complementary to sequences beyond the 3’ terminus of PR mRNA modulate expression of PR, recruit argonaute to a 3’-noncoding transcript, alter occupancy of RNA polymerase II, induce chromatin changes at the PR promoter, and affect responses to physiologic stimuli. We find that the promoter and 3’ terminal regions of the PR locus are in close proximity, providing a potential mechanism for RNA-mediated control of transcription over long genomic distances. Computational analysis led to identification of an inhibitory miRNA that targets the 3’ downstream region and modulates PR expression. These results extend the potential for small RNAs to regulate transcription to regions beyond the 3’ termini of mRNA.
