The mouse tiling array (2006-07-17MM8 tiling_set38), which covers the second half of the X chromosome (ChrX:93,883,966- 165,556,020, UCSC mouse genome Feb 2006 assembly) and the complete Y chromosome, was used in this study to closely compare the H4K16 acetylation pattern between Jarid1c and Jarid1d present on the same array. Analysis was done using the manufacturer software.Supporting Information
