One of the most enriched DNA elements in promoters and enhancers of genes specifically active in ESCs is the CCAAT box, which is recognized by NF-Y, a trimer with histone-like subunits--NF-YB/NF--YC--and the sequence-specific NF-YA. We show that the levels of the short NF-YA isoform--NF-YAs--is high in mouse ESCs (mESCs) and drops after differentiation; a dominant negative mutant affects expression of important stem cells genes, directly and indirectly. Protein transfections of TAT-NF-YAs stimulate growth and compensate for withdrawal of leukemia inhibitory factor (LIF) in cell cultures. Bioinformatic analysis identifies NF-Y sites as highly enriched in genomic loci of stem TFs in ESCs. Specifically, 30%-50% of NANOG peaks have NF-Y sites and indeed NF-Y-binding is required for NANOG association to DNA. These data indicate that NF-Y belongs to the restricted circle of TFs that govern mESCs, and, specifically, that NF-YAs is the active isoform in these cells."xsd:string |
