Biochem/physiol Actions

KL201 is a circadian clock modulator that lengthens a circadian period in cells and tissues. KL201 selectively regulate cryptochrome 1 (Cry1). It binds to FAD-binding pocket of CRY1 preventing interaction with FBXL3 and ubiquitin-dependent degradation.

Cryptochrome 1 (CRY1) and CRY2 are core regulators of the circadian clock, and the development of isoform-selective modulators is important for the elucidation of their redundant and distinct functions. Here, we report the identification and functional characterization of a small-molecule
