Study finds ways to enhance transcription factor activity

Transcription factors regulate gene expression by binding specific sequences on DNA, which is an essential step to producing messenger RNAs from protein-coding genes. Denes Hnisz's lab, in collaboration with Martin Vingron's lab at the MPIMG, has discovered that human transcription factors don't typically use their full potential. Instead, important protein regions within transcription factors encode chemical features that generate submaximal transcriptional activity.
