| Hazard Information | Back Directory | [Description]
KL-001 (309928-48-1) is a novel tool that specifically interacts with cryptochrome (CRY) preventing its ubiquitin-dependent degradation resulting in lengthening of the circadian period. KL-001-mediated CRY stabilization inhibits glucagon-induced gluconeogenesis in primary hepatocytes.1?Binds to the FAD-binding pocket of CRY2 as determined by co-crystal structure.2?KL-001 induces an increase in period along with simultaneous reduction in amplitude of circadian reporter expression3 in mammalian cells. | [Uses]
KL001 is a small molecule that specifically interacts with cryptochrome (CRY). KL001 prevented ubiquitin-dependent degrdation of CRY, resulting in lengthening of the circadian period. KL001-mediated CRY stabilization inhibited glucagon-induced gluconeogenesis in primary hepatocytes making it a tool to study the regulation of CRY-dependent physiology and aid development of clock-based therapeutics of diabetes. | [Biochem/physiol Actions]
KL001 stabilizes cryptochrome (CRY), preventing ubiquitin-dependent degradation. CRY proteins are part of a feedback loop, acting as transcription repressors to inhibit CLOCK-BMAL1 components of the circadian clock. KL001 stabilization of CRY proteins results in lengthening of the circadian period, and also inhibited glucagon-induced gluconeogenesis in primary hepatocytes. Other compounds affecting circadian rhythms include Casein kinase I (CKI) inhibitors such as longdaysin (Sigma Prod. No. SML0127) and synthetic ligands for the nuclear receptors REV-ERB such as SR8278 (Sigma Prod. No. S9576), but KL001 appears to be the first small molecule that specifically acts on CRY proteins. | [storage]
