GSE120646	Other	The maternal to zygotic transition MZT is a conserved and fundamental process during which the embryo undergoes dramatic reprogramming to convert maternal environment to embryonic driven programing. However how the maternally supplied transcripts are dynamically regulated during MZT remains largely unknown. Herein through genome wide profiling of RNA 5 methylcytosine m5C in zebrafish early embryos we show that m5C methylated maternal mRNAs display higher stability during MZT. We identify that the Y box binding protein 1 Ybx1 prefers to recognizing m5C modified mRNAs through p p interaction with a key residue Trp45 in its cold shock domain CSD which plays essential roles in maternal mRNA stability and early embryogenesis of zebrafish. Cooperated with an mRNA stabilizer Pabpc1a Ybx1 promotes the stability of its target mRNAs in an m5C dependent manner.

GSE120646	Other	The maternal to zygotic transition MZT is a conserved and fundamental process during which the embryo undergoes dramatic reprogramming to convert maternal environment to embryonic driven programing. However how the maternally supplied transcripts are dynamically regulated during MZT remains largely unknown. Herein through genome wide profiling of RNA 5 methylcytosine m5C in zebrafish early embryos we show that m5C methylated maternal mRNAs display higher stability during MZT. We identify that the Y box binding protein 1 Ybx1 prefers to recognizing m5C modified mRNAs through p p interaction with a key residue Trp45 in its cold shock domain CSD which plays essential roles in maternal mRNA stability and early embryogenesis of zebrafish. Cooperated with an mRNA stabilizer Pabpc1a Ybx1 promotes the stability of its target mRNAs in an m5C dependent manner. Our study demonstrates a novel mechanism of RNA m5C methylation regulated maternal mRNA stability during zebrafish MZT highlighting the critical role of m5C mRNA methylation in early development. Overall design: Examination of Ybx1 binding sites and Ybx1 binding m5C sites in zebrafish embryo.
