SRP178734 PRJNA512910 Genomic mapping of O-GlcNAc in mESCs We mapped the genomic distribution of O-GlcNAcylated proteins in mouse embryonic stem cells using a pan-specific O-GlcNAc antibody. We identified thousands of target loci occupied by O-GlcNAcylated proteins, and we found these loci enriched in transcription start sites. Mus musculus
