These results suggest that many of the cell and tissue specific phenotypes in ele mutant embryos are secondary to altered expression of modules of developmental regulatory genes that characterise or promote transitions in cell state and require the correct function of Slbp dependent histone and chromatin regulatory genes.,ENA FIRST PUBLIC:2018 11 02|ENA LAST UPDATE:2018 11 01,,,mutant1,SAMEA5059843,Department of Cell and Developmental Biology,ENA FIRST PUBLIC:2018 11 02T17:01:55Z|ENA LAST UPDATE:2018 11 01T15:11:02Z|External Id:SAMEA5059843|INSDC center name:Department of Cell and Developmental Biology|INSDC first public:2018 11 02T17:01:55Z|INSDC last update:2018 11 01T15:11:02Z|INSDC status:public|Submitter Id:ele mutant1|common name:zebrafish|sample name:ele mutant1|scientific name:Danio rerio,,,,,,,,,Illumina HiSeq 3000 paired end sequencing,ena EXPERIMENT Department of Cell and Developmental Biology 01 11 2018 15:10:57:716 1,unspecified,1,,,RNA-Seq,TRANSCRIPTOMIC,other,PAIRED,ILLUMINA,Illumina HiSeq 3000,,ERP111778,Illumina HiSeq 3000 paired end sequencing,ENA FIRST PUBLIC:2018 11 02|ENA LAST UPDATE:2018 11 16,ele_A_CGATGT_L004_R1_001.fastq.gz ele_A_CGATGT_L004_R2_001.fastq.gz,fastq fastq,2181939600.0,10909698.0,ena RUN Department of Cell and Developmental Biology 01 11 2018 15:10:57:717 1,0:100 1:100,A:578028200;C:516249107;G:510965740;T:576417363;N:279190,100,100,,,578028200,516249107,510965740,576417363,279190,ERX2871394,ERS2871014,ERA1643817,Department of Cell and Developmental Biology|European Nucleotide Archive,Department of Cell and Developmental Biology,2,0.94968,0.94939,0.1131,0.11293,0.66245,0.66251,0.46654,0.47475,100,100,B,B,biological fallback assumption,illumina,hiseq_era,unknown,other,unknown,bulk,unknown,unknown,,Unknown,2018-11-01,Undetermined,Embryo,Undetermined,Embryo Imprecise 9717,ERR3842002,ERX3854564,ERS4268611,ERP116106,PRJEB33323,Deconstructing the individual steps of vertebrate translation initiation,ena-STUDY-Computational Biology Unit-03-07-2019-10:11:34:314-422,Other,In eukaryotes the number of ribosomes synthesizing a given protein depends on how many are recruited to its mRNA their success in navigating its five prime untranslated region UTR and whether they recognize its start codon.

Moreover we show that mRNA tail lengths are dynamically regulated during vertebrate embryogenesis at an isoform specific level correlating with mRNA decay. Finally we identify non A bases within polyA tails of various lengths and reveal their distribution during vertebrate embryogenesis. Overall Nano3P seq is a simple and robust method for accurately estimating transcript levels tail lengths and tail composition heterogeneity in individual reads with minimal library preparation biases both in the coding and non coding transcriptome.,ENA FIRST PUBLIC:2022 10 10|ENA LAST UPDATE:2022 10 10,,Zebrafish PolyA Selected RNA 4hpf,Zebrafish pA selected,SAMEA110100410,CENTER FOR GENOMIC REGULATION (CRG),ENA FIRST PUBLIC:2022 10 10|ENA LAST UPDATE:2022 10 10|External Id:SAMEA110100410|INSDC center alias:CENTER FOR GENOMIC REGULATION CRG|INSDC center name:CENTER FOR GENOMIC REGULATION CRG|INSDC first public:2022 10 10T00:20:53Z|INSDC last update:2022 10 10T00:20:53Z|INSDC status:public|Submitter Id:Zebrafish pA selected|common name:zebrafish|sample name:Zebrafish pA selected,,,,,,,,,MinION sequencing,ena EXPERIMENT TAB 13 06 2022 16:07:52:807 811,cDNA852361 ZFPA4R1,1,,,RNA-Seq,TRANSCRIPTOMIC,other,SINGLE,OXFORD_NANOPORE,MinION,,ERP138294,MinION sequencing,ENA FIRST PUBLIC:2022 10 10|ENA LAST UPDATE:2022 10 10,cDNA852361_ZFPA4R1.tar.gz,nanopore,348224822.0,233101.0,ena RUN TAB 13 06 2022 16:07:52:807 812,0:1493.88,A:88963756;C:76104775;G:73909507;T:109246784;N:0,1493,,,,88963756,76104775,73909507,109246784,0,ERX9385635,ERS12199235,ERA15547404,CENTER FOR GENOMIC REGULATION (CRG)|European Nucleotide Archive,CENTER FOR GENOMIC REGULATION (CRG),1,0.34147,,0.26829,,0.99993,,0.16666,,1537,,T,,long read,ont,ont,3prime,poly_a,unknown,bulk,unknown,unknown,,Spain,2022-10-10,Blastula,Embryo,Undetermined,Embryo Imprecise 25182,SRR25670729,SRX21396042,SRS18636200,SRP455680,PRJNA1006406,Control of polyA tail length and translation in vertebrate oocytes and early embryos,GSE241107,Other,During oocyte maturation and early embryonic development polyA tail lengths strongly influence mRNA translation. However how tail lengths are controlled at different developmental stages has been unclear. Here we performed tail length and translational profiling of mRNA reporter libraries each with > 10 million three prime UTR sequence variants in frog oocytes and embryos and fish embryos. These analyses revealed that the UUUUA motif specifies cytoplasmic polyadenylation and identified diverse context features that modulate the activity of this 5 mer. Additional sequence motifs drive stage specific deadenylation in embryos and UUUUA and C rich motifs drive tail length independent translational repression in oocytes. A neural network model accurately predicts tail length change during oocyte maturation in frogs mice and humans. Analyses of human sequence variants showed that those predicted to disrupt tail length control have been under negative selection implying that our insights into control of polyA tail length and translation have implications for human health and fertility. Overall design: Sythetic mRNA reporter libraries with random three prime UTR sequences under four different sequence contexts were injected into frog oocytes and embryos and fish embryos. PolyA tail lengths were measured to at different developmental stages to examine sequence motifs that caused tail length changes. At the same time polyA tail lengths of endogenous mRNAs from frog oocytes and embryos fish embryos and mouse oocytes were measured to investiage how their tail lengths were controlled.

However how tail lengths are controlled at different developmental stages has been unclear. Here we performed tail length and translational profiling of mRNA reporter libraries each with > 10 million three prime UTR sequence variants in frog oocytes and embryos and fish embryos. These analyses revealed that the UUUUA motif specifies cytoplasmic polyadenylation and identified diverse context features that modulate the activity of this 5 mer. Additional sequence motifs drive stage specific deadenylation in embryos and UUUUA and C rich motifs drive tail length independent translational repression in oocytes. A neural network model accurately predicts tail length change during oocyte maturation in frogs mice and humans. Analyses of human sequence variants showed that those predicted to disrupt tail length control have been under negative selection implying that our insights into control of polyA tail length and translation have implications for human health and fertility. Overall design: Sythetic mRNA reporter libraries with random three prime UTR sequences under four different sequence contexts were injected into frog oocytes and embryos and fish embryos. PolyA tail lengths were measured to at different developmental stages to examine sequence motifs that caused tail length changes. At the same time polyA tail lengths of endogenous mRNAs from frog oocytes and embryos fish embryos and mouse oocytes were measured to investiage how their tail lengths were controlled.

However how tail lengths are controlled at different developmental stages has been unclear. Here we performed tail length and translational profiling of mRNA reporter libraries each with > 10 million three prime UTR sequence variants in frog oocytes and embryos and fish embryos. These analyses revealed that the UUUUA motif specifies cytoplasmic polyadenylation and identified diverse context features that modulate the activity of this 5 mer. Additional sequence motifs drive stage specific deadenylation in embryos and UUUUA and C rich motifs drive tail length independent translational repression in oocytes. A neural network model accurately predicts tail length change during oocyte maturation in frogs mice and humans. Analyses of human sequence variants showed that those predicted to disrupt tail length control have been under negative selection implying that our insights into control of polyA tail length and translation have implications for human health and fertility. Overall design: Sythetic mRNA reporter libraries with random three prime UTR sequences under four different sequence contexts were injected into frog oocytes and embryos and fish embryos. PolyA tail lengths were measured to at different developmental stages to examine sequence motifs that caused tail length changes. At the same time polyA tail lengths of endogenous mRNAs from frog oocytes and embryos fish embryos and mouse oocytes were measured to investiage how their tail lengths were controlled.

However how tail lengths are controlled at different developmental stages has been unclear. Here we performed tail length and translational profiling of mRNA reporter libraries each with > 10 million three prime UTR sequence variants in frog oocytes and embryos and fish embryos. These analyses revealed that the UUUUA motif specifies cytoplasmic polyadenylation and identified diverse context features that modulate the activity of this 5 mer. Additional sequence motifs drive stage specific deadenylation in embryos and UUUUA and C rich motifs drive tail length independent translational repression in oocytes. A neural network model accurately predicts tail length change during oocyte maturation in frogs mice and humans. Analyses of human sequence variants showed that those predicted to disrupt tail length control have been under negative selection implying that our insights into control of polyA tail length and translation have implications for human health and fertility. Overall design: Sythetic mRNA reporter libraries with random three prime UTR sequences under four different sequence contexts were injected into frog oocytes and embryos and fish embryos. PolyA tail lengths were measured to at different developmental stages to examine sequence motifs that caused tail length changes. At the same time polyA tail lengths of endogenous mRNAs from frog oocytes and embryos fish embryos and mouse oocytes were measured to investiage how their tail lengths were controlled.

However how tail lengths are controlled at different developmental stages has been unclear. Here we performed tail length and translational profiling of mRNA reporter libraries each with > 10 million three prime UTR sequence variants in frog oocytes and embryos and fish embryos. These analyses revealed that the UUUUA motif specifies cytoplasmic polyadenylation and identified diverse context features that modulate the activity of this 5 mer. Additional sequence motifs drive stage specific deadenylation in embryos and UUUUA and C rich motifs drive tail length independent translational repression in oocytes. A neural network model accurately predicts tail length change during oocyte maturation in frogs mice and humans. Analyses of human sequence variants showed that those predicted to disrupt tail length control have been under negative selection implying that our insights into control of polyA tail length and translation have implications for human health and fertility. Overall design: Sythetic mRNA reporter libraries with random three prime UTR sequences under four different sequence contexts were injected into frog oocytes and embryos and fish embryos. PolyA tail lengths were measured to at different developmental stages to examine sequence motifs that caused tail length changes. At the same time polyA tail lengths of endogenous mRNAs from frog oocytes and embryos fish embryos and mouse oocytes were measured to investiage how their tail lengths were controlled.

However how tail lengths are controlled at different developmental stages has been unclear. Here we performed tail length and translational profiling of mRNA reporter libraries each with > 10 million three prime UTR sequence variants in frog oocytes and embryos and fish embryos. These analyses revealed that the UUUUA motif specifies cytoplasmic polyadenylation and identified diverse context features that modulate the activity of this 5 mer. Additional sequence motifs drive stage specific deadenylation in embryos and UUUUA and C rich motifs drive tail length independent translational repression in oocytes. A neural network model accurately predicts tail length change during oocyte maturation in frogs mice and humans. Analyses of human sequence variants showed that those predicted to disrupt tail length control have been under negative selection implying that our insights into control of polyA tail length and translation have implications for human health and fertility. Overall design: Sythetic mRNA reporter libraries with random three prime UTR sequences under four different sequence contexts were injected into frog oocytes and embryos and fish embryos. PolyA tail lengths were measured to at different developmental stages to examine sequence motifs that caused tail length changes. At the same time polyA tail lengths of endogenous mRNAs from frog oocytes and embryos fish embryos and mouse oocytes were measured to investiage how their tail lengths were controlled.
