A small molecule modulates circadian rhythms through phosphorylation of the period protein

Angew Chem Int Ed Engl. 2011 Nov 4;50(45):10608-11. doi: 10.1002/anie.201103915. Epub 2011 Sep 26.

Abstract

Time shift: A high-throughput cell-based screen identified a benzothiazole analogue, LH846, which induces period lengthening of the circadian rhythm. Affinity chromatography coupled with mass spectrometry and genomic analysis identified protein kinase CKIδ as the biological target of LH846 (see picture).
