Hsp17 thermometer
In molecular biology, the Hsp17 thermometer is an RNA element (RNA thermometer) found in the 5' UTR of Hsp17 mRNA.[1] Hsp17 is a cyanobacterial heat shock protein belonging to the Hsp20 family.[2]
At physiological temperature (28 degrees Celsius) the Hsp17 thermometer forms a hairpin structure, preventing translation of Hsp17. Under heat shock conditions the hairpin structure melts and translation takes place.[1]
