| description | Abstract The mammalian early embryo development requires translation of maternal mRNA inherited from the oocyte. While poly(A) tail length influences mRNA translation efficiency during the oocyte-to-embryo transition (OET), molecular mechanisms regulating maternal RNA poly(A) tail length are not fully understood. In this study, we identified MARTRE, a previously uncharacterized protein family (MARTRE1-MARTRE6), as regulators expressed during mouse OET that modulate poly(A) tail length. MARTRE inhibits deadenylation through the direct interaction with the deadenylase CCR4-NOT, and ectopic expression of Martre stabilized mRNA by attenuating poly(A) tail shortening. Deletion of the Martre gene locus results in shortened poly(A) tails and decreased translation efficiency of actively translated mRNAs in mouse zygotes, but does not affect maternal mRNA decay. MARTRE proteins thus fine-tune maternal mRNA translation by negatively regulating the deadenylating activity of CCR4-NOT. Moreover, Martre knockout embryos show delayed 2-cell stage progression and compromised preimplantation development. Together, our findings highlight protection of long poly(A) tails from active deadenylation as an important mechanism to coordinate translation of maternal mRNA. |
