We found the genome-wide co-localization of Qki-5 and Srebp2. Notably, the genomic distribution analysis revealed that Qki-5 and Srebp2 highly co-occupied the regions of the promoter/transcription start site (TSS), where active transcription was taken place in a oligodendrocyte-specific manner, which was indicated by Pol II binding events. GO analysis of the genes whose promoters were co-bound by Qki-5, Srebp2, and Pol II showed a significant enrichment of the Srebp2-mediated cholesterol biosynthesis pathway, and Qki depletion led to reduced recruitment of Srebp2 and Pol II on the promoters of the genes involved in cholesterol biosynthesis. These data suggest Qki-5 as a potential transcription co-activator of Srebp2-mediated cholesterol biosynthesis in oligodendrocytes.
