SUMO safeguards somatic and pluripotent cell identities by enforcing distinct chromatin states [SUMO-ChIP-seq]
Mouse embryonic fibroblasts (MEFs) were generated from Ubc9fl/- and Ubc9+/+ embryos (E13.5). MEFs were treated with tamoxifen for six days to cause CreERT2 activation, and induce Ubc9 floxed allele deletion. We determined the ChIP-seq profiles of SUMO-1 and SUMO-2 using chromatin of wild-type MEFs Ubc9+/+ and of the corresponding Ubc9 KO MEFs which are entirely depleted for sumoylation. The analysis revealed the nearly complete absence of genome-wide binding of SUMO-1 and SUMO-2 in Ubc9-/- MEFs, attesting for antibody specificities. Overall design: One replicate per condiition and mark
