During the Maternal to Zygotic Transition MZT  thousands of maternal transcripts are regulated  however  how different cis elements and trans factors are integrated to determine mRNA stability is still poorly understood. Here  we show that most transcripts are under combinatorial regulation by multiple decay pathways during zebrafish MZT. Using a massively parallel reporter assay  we identified cis regulatory sequences in the three prime UTR  including poly U motifs that are associated with mRNA stability. In contrast  miR 430 target sequences  UAUUUAUU AU rich elements ARE  CCUC and CUGC elements emerged as destabilizing motifs  with miR 430 and AREs causing mRNA deadenylation upon genome activation. We identified trans factors by profiling RNA protein interactions and found that poly U binding proteins are preferentially associated with three prime UTR sequences and stabilizing motifs. We demonstrate that this activity is antagonized by poly C motifs and correlated with protein binding. Finally  we integrated these regulatory motifs into a machine learning model that predicts reporter mRNA stability in vivo.This is the RESA libraries part of the study.", null, null, null, "RESA   WT a Am 6h DL B2", "RESA   WT a Am 6h DL B2 AGN000466", null, "strain:TU/AB|age:6|sex:pooled male and female|tissue:embryo|treatment:transcriptome 6h aAm AGN000129 injection alpha am|molecule:RNA|sample ref:AGS000444|replicate ref:AGN000466|replicate order:2|BioSampleModel:Model organism or animal", null, null, null, null, null, null, null, null, "RESA   WT a Am 6h DL B2", "AGR000598", "AGR000598", "RNA", null, null, "OTHER", "TRANSCRIPTOMIC", "unspecified", "SINGLE", "ILLUMINA", "Illumina HiSeq 2000", null, "SRP189389", null, null, "AGR000598_R1.fastq.gz", "fastq", 83271604.0, 1095679.0, "AGR000598 R1.fastq.gz", "0:76", "A:24099348;C:20368786;G:21051352;T:17745573;N:6545", 76, null, null, null, 24099348, 20368786, 21051352, 17745573, 6545, "SRX5574111", "SRS4536688", "SRA865803", "Yale_Giraldez|Genetics", "Yale_Giraldez_Group", 1, 8e-05, null, 3e-05, null, 0.99983, null, 0.5, null, 76, null, "T", null, "under 1.2% mapping rate", "illumina", "hiseq_era", "unknown", "unknown", "unknown", "bulk", "unknown", "unknown", null, "United States", "2019-05-31", "Undetermined", "Embryo", "Embryo Imprecise", "All anatomical structures"]], "columns": ["rowid", "run.accession", "experiment.accession", "sample.accession", "study.accession", "bioproject", "study.title", "study.alias", "study.type", "study.abstract", "study.attributes", "study.PMIDs", "sample.description", "sample.title", "sample.alias", "sample.centername", "sample.attributes", "GEOsample.title", "GEOsample.dataprocessing", "GEOsample.source", "GEOsample.treatmentprotocol", "GEOsample.extractprotocol", "GEOsample.growthprotocol", "GEOsample.characteristics", "GEOsample.accession", "experiment.title", "experiment.alias", "experiment.library_name", "experiment.design_description", "experiment.library_construction_protocol", "experiment.attributes", "experiment.library_strategy", "experiment.library_source", "experiment.library_selection", "experiment.library_layout", "experiment.platform", "experiment.instrument_model", "experiment.spot_descriptor", "experiment.study_ref", "run.title", "run.attributes", "run.filename", "run.semantic_name", "run.total_bases", "run.total_spots", "run.alias", "run.read_lengths", "run.base_counts", "run.r1_length", "run.r2_length", "run.r3_length", "run.r4_length", "run.Acount", "run.Ccount", "run.Gcount", "run.Tcount", "run.Ncount", "run.experiment", "run.pool_member", "submission.accession", "submission.srasource", "submission.bioprojectsource", "seqdetective.n_mates", "seqdetective.mapping_rate.mate1", "seqdetective.mapping_rate.mate2", "seqdetective.nofeature_rate.mate1", "seqdetective.nofeature_rate.mate2", "seqdetective.sparsity.mate1", "seqdetective.sparsity.mate2", "seqdetective.pos_strand_rate.mate1", "seqdetective.pos_strand_rate.mate2", "seqdetective.readlen.mate1", "seqdetective.readlen.mate2", "seqdetective.judgement.mate1", "seqdetective.judgement.mate2", "seqdetective.judgement.reason", "platform_family", "instrument_generation", "read_bias", "selection_class", "prep_kit", "sc_or_bulk", "tech_class", "technology", "tech_variant", "submission.bioprojectsource.country", "earliest_date", "devstage_curation", "devstage_curation_coarse", "tissue_curation", "tissue_curation_coarse"], "primary_keys": ["rowid"], "primary_key_values": ["51369"], "units": {}, "query_ms": 8.751238012337126}
