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. Required during meiotic maturation to silence certain maternal mRNAs translationally. Does not require an adenosine residue at the 3' end, however, the addition of 25 non-adenylate residues at the 3' terminus, or a 3' terminal phosphate is inhibitory. Involved in dormant mRNAs regulation during oocyte maturation by counteracting polyadenylation mediated by papd4/gld2nt in immature eggs. During maturation it is excluded from the ribonucleoprotein complex, allowing poly(A) elongation by papd4/gld2nt and activation of mRNAs. [-]
