The major eukaryotic deadenylase complex CCR4-NOT contains two deadenylase components, CCR4 and CAF1, for which mammalian CCR4 is encoded byCnot6orCnot6lparalogs. We show thatCnot6lapparently supplies the majority of CCR4 in the maternal CCR4-NOT in mouse, hamster, and bovine oocytes. Deletion ofCnot6lyielded viable mice, butCnot6l−/−females exhibited ∼40% smaller litter size. The main onset of the phenotype was post-zygotic: fertilizedCnot6l−/−eggs developed slower and arrested more frequently thanCnot6l+/−eggs, suggesting that maternal CNOT6L is necessary for accurate oocyte-to-embryo transition. Transcriptome analysis revealed major transcriptome changes inCnot6l−/−ovulated eggs and one-cell zygotes. In contrast, minimal transcriptome changes in preovulatoryCnot6l−/−oocytes were consistent with reportedCnot6lmRNA dormancy. A minimal overlap between transcripts sensitive to decapping inhibition andCnot6lloss suggests that decapping and CNOT6L-mediated deadenylation selectively target distinct subsets of mRNAs during oocyte-to-embryo transition in mouse.}, publisher={Life Science Alliance, LLC}, author={Horvat and Fulka and Jankele and Malik and Jun and Solcova and Sedlacek and Vlahovicek and Schultz and Svoboda}, year={2018}, month={Jul} }
