Extensive binding of poorly characterized human transcription factors to genomic dark matter

Abstract The functional impact of a large portion of the human genome known as “dark matter DNA”, which is composed mainly of repeat sequences, remains unknown. The genome also encodes many putative and poorly characterized transcription factors. Here, we determine genomic bindin...

An expanded codebook of human transcription factor DNA-binding specificity

Abstract Gene expression is regulated by transcription factors (TFs), which recognize specific DNA sequence motifs. Several hundred putative human TFs, identified mainly by an apparent DNA-binding domain, lack known binding motifs 1 . Furthermore, even for well-characterized TFs,...
