We analyzed the RNA structure dynamics among different development stages. Also we studied which factors regulate maternal gene decay by RNA structure switch. Overall design: icSHAPE of 12 samples from zebrafish embryos at six different early development stages and 4 samples from Elavl1a deficient zebrafish embryos at sphere and shield stages including two treated with DMSO as control and two treated with NAIN3 for each stage or condition. RNA seq of 6 samples from zebrafish embryos at 2 4 6 h.p.f. and 4 samples from Elavl1a deficient zebrafish embryos at 4 and 6 h.p.f. including two biological replicates. iCLIP seq of 4 samples from flag elavl1a mRNA injected zebrafish embryos at xxx and 6 h.p.f. including two biological replicates.		pubmed:32423473		elavl1a morphant 4h rna seq rep2	GSM3409397		source name:elavl1a morphant 4h rna seq rep2\|strain:AB\|tissue:zebrafish embryos\|genotype/variation:elavl1a morphants zebrafish embryos cells\|age:4hpf	elavl1a morphant 4h rna seq rep2	trimmed three prime adaptor from reads by cutadapt trimmed low quality bases by trimmomatic collapsed duplicated reads as icSHAPE pipeline trimmed the leading 13nt UMI mapping reads to zebrafish reference transcriptomez10 by bowtie2 using the same parameters in icSHAPE pipeline calculate rpkm as icshape pipeline calculate reverse transcription stop sitesRT stop as icshape pipeline RT stop was normalized by using sliding window then icSHAPE score was calculated as icshape pipeline Genome build: z10 Supplementary files format and content: tab delimited text files for icshape files. First column is the Refseq ID second is transcript length third is RPKM then every column is the nucleotide resolution icSHAPE score. NULL means no confident score. Tab delimited text files for read counts and rpkm files. First column is the Refseq ID second is transcript length third is the unique mapped reads count fourth is the mulitple mapped reads count fifth is the RPKM.	elavl1a morphant 4h rna seq rep2	For Elavl1a morphants generation morpholino oligonucleotides of elavl1a were injected into one cell stage embryos then embryos were harvested at desired stages	The RNA or modified RNA was extracted or cleaned up and eluted in RNase free water by using TRIzol® Reagent invitrogen.To enrich polyA RNA the total RNA was subjected to polyA selection. For icSHAPE the in vivo modified RNA and unmodified RNA were biotinylated by copper free click reaction followed by fragmentation. The fragmented RNA was end repaired by incubation at 37°C for 1 hours with the following mix 70 mM Tris 7.0 18mM MgCl2 5mM DTT 4 U/µl RiboLock 0.1 U/µl FastAP Life Technology 2 U/µl T4 PNKNEB before 3’ adapter ligation with addition of 10 µl ligation mix 5mM DTT 0.5µM 5’ adenylated and 3’ blocked linker 3’ bio for unmodified 3’ ddc for modified 0.66 U/µl T4 RNA ligase NEB M0437M 15% PEG8000 1X RNA ligase buffer and incubation at 25°C for extra 3 hours. Then the excess adaptor was removed as described below. The purified RNA was incubated in the mix of 1µl FastAP 0.2µl SSB Promega 0.8µl Ribolock and 1µl 5’ Deadenylase NEB in 1X NEB buffer 2 NEB at 30°C for 90 min. And then 1µl RecJf NEB was added with another incubation at 37°C for 1 hour. The following procedures including reverse transcription biotin streptavadin enrichment size selection of cDNA circularization and PCR amplification were the same as described in the standard protocol. For RNA seq， Fragmented mRNA was used for library construction using the KAPA Stranded mRNA Seq Kit KAPA according to manufacturer’s protocol.	Zebrafish wild type strain AB was raised in system water at 28.5°C under standard conditions.	strain:AB\|tissue:zebrafish embryos\|genotype/variation:elavl1a morphants zebrafish embryos cells\|age:4hpf	GSM3409397	GSM3409397: elavl1a morphant 4h rna seq rep2; Danio rerio; RNA Seq	GSM3409397		1	The RNA or modified RNA was extracted or cleaned up and eluted in RNase free water by using TRIzol® Reagent invitrogen.
