Short name: 5_3_exoribonuclease_1

Family relationships

Description

5'-3'-exoribonucleases are enzymes that degrade RNA by removing terminal nucleotides from the 5' end. 5'-3'exoribonuclease type 1 (Xrn1, also known as kem1) occurs in animal and fungal lineages. In Saccharomyces cerevisiae, Xrn1 can be activated by Dcs1, a non-essential hydrolase that involved in mRNA decapping. The activation of Xrn1 by Dcs1 is important for respiration [PMID: 22570495].
