Consistent with this interpretation , a mutant form of XRN1 , which encodes a 5 ' - 3 ' exonuclease , was identified as an extragenic suppressor that increases the half - life of rhis4 mRNA , leading to a 10 - fold increase in steady - state mRNA levels compared to the wild - type HIS4 mRNA level .
 GENE: XRN1; GENE: rhis4 mRNA; GENE: wild - type HIS4 mRNA
