UniProt Comments
3'-exoribonuclease that has a preference for poly(A) tails of mRNAs, thereby efficiently degrading poly(A) tails. Exonucleolytic degradation of the poly(A) tail is often the first step in the decay of eukaryotic mRNAs. Essential for early development, possibly by participating in silencing certain maternal mRNAs translationally. May have a pivotal role in stress response.
