| Extraction protocol |
Zygotes were collected at 17h post hCG injection and cultured with or without BAY1251152 (Cdk9in or Noinject), or subjected to Trim-Away for SPT5 (Spt5KD), NELF-E (NelfEKD) or IgG. Embryos were cultured until 46h post hCG, washed in PBS and flash-frozen in lysis buffer.
Libraries for single embryo RNA-seq were prepared with Smart-Seq2 protocol (PMID: 24385147). The quality of the libraries was assessed using a 2100 Bioanalyzer (Agilent). Samples were paired-end sequenced at PE150 on an Illumina NovaSeq 6000 platform.

| Data processing |
The reference genome (GRCm38.dna.primary_assembly.fa) and annotation files (GRCm38.101.gtf) were modified by concatenating the mouse genome with ERCC (source: Thermofisher) and the construct ‘pGEMHE-mCherry-mTrim21’ fasta and gtf files, respectively. The endogenous Trim21 locus was masked using bedtools (version 2.29.0).
The modified reference fasta file was used to prepare STAR index files using rsem-prepare-reference (rsem version 1.3.3). Paired-end reads were aligned using STAR (version 2.7.6a) with parameters --quantMode TranscriptomeSAM GeneCounts --outSAMtype BAM SortedByCoordinate.
Downstream analysis was carried out on read counts per gene calculated by STAR.
