| Extraction protocol |
Populations of pachytene spermatocytes and round spermatids (purity 89-90%) were recovered using a StaPut gradient as previously described (Bellve et al, 1993). Cells were washed once in PBS and then split into two aliquots. One aliquot (for ChIP) was fixed in 1% formaldehyde then quenched with 2.5M glycine, while the second (for RNA) was left unfixed. Both fixed and unfixed aliquots were snap frozen in liquid nitrogen, then stored at -80C. ChIP was performed as previously described (Lesch et al 2013).
RNA-seq libraries were prepared using an Apollo 324 library prep instrument with supplied reagents (Integenx).

| Description |
Testes from Monodelphis domestica were obtained from animals culled from a colony maintained at the Texas Biomedical Research Institute.
|
| Data processing |
Image analysis and base calling was done using the standard Illumina pipeline for HiSeq2500.
Data was quality-filtered using fastq_quality_filter from the FASTX toolkit with the following parameters: -q 20 -p 80.
For RNA-seq, FPKM values were generated using Cufflinks 2.2 with default parameters, except that a transcript gtf was supplied (-G option), and average fragment length of the library was supplied under the -m flag.
genome build: monDom5
processed data files format and content: All files are tab-delimited text (.txt). For RNA-seq, FPKM is reported for each Ensembl (build 75) transcript and gene.
