Notch Inhibitor Screening Reveals an Unexpected HES1 Heterodimer.
JOURNAL OF BIOLOGICAL CHEMISTRY(2018)
摘要
Notch signaling plays critical roles in cancer progression, motivating efforts to identify inhibitors of this pathway. Perron et al. report a small-molecule screen intended to discover compounds that could interfere with the downstream transcription factor HES1. Target validation of their compounds unexpectedly identified a novel HES1-interacting protein, prohibitin 2. This highlights a new mechanism to block Notch signaling and prompting further exploration of HES1 biology.
