- The PrfA thermoregulator UTR is an RNA thermometer found in the 5' UTR of the prfA gene. In Listeria monocytogenes, virulence genes are maximally expressed at 37 °C (human body temperature) but are almost silent at 30 °C. The genes are controlled by , a transcriptional activator whose expression is thermoregulated. It has been shown that the untranslated mRNA (UTR) preceding prfA, forms a secondary structure, which masks the ribosome binding region. It is thought that at 37 °C, the hairpin structure 'melts' and the SD sequence is unmasked. (en)
