Crystal structure of mammalian cryptochrome in complex with a small molecule competitor of its ubiquitin ligase
Dear Editor, The cryptochrome (CRY) flavoproteins are criti cal components of the mammalian molecular circa dian clock, which operates through an auto-regulatory transcription-translation feedback loop [1]. In this clockwork, a pair of transcription factors, CLOCK and BMAL1, drive the expression of...

Summary: | Dear Editor, The cryptochrome (CRY) flavoproteins are criti cal components of the mammalian molecular circa dian clock, which operates through an auto-regulatory transcription-translation feedback loop [1]. In this clockwork, a pair of transcription factors, CLOCK and BMAL1, drive the expression of CRYs, Periods (PERs), and other clock-controlled genes, while CRYs and PERs heterodimerize and repress their own gene expression by inhibiting CLOCK-BMALl-mediated transcription [2, 3]. To establish rhythmic protein oscillation, CRYs are ubiq- uitinated by the SCF^FBXL3 ubiquitin ligase and targeted for rapid proteasomal degradation [4-6]. |
