Isojima, Yasushi published the artcileCkIε/δ-dependent phosphorylation is a temperature-insensitive, period-determining process in the mammalian circadian clock, Formula: C20H17FO4S, the publication is Proceedings of the National Academy of Sciences of the United States of America (2009), 106(37), 15744-15749, S15744/1-S15744/74, database is CAplus and MEDLINE.

A striking feature of the circadian clock is its flexible yet robust response to various environmental conditions. To analyze the biochem. processes underlying this flexible-yet-robust characteristic, we examined the effects of 1260 pharmacol. active compounds in mouse and human clock cell lines. Compounds that markedly (>10 s.d.) lengthened the period in both cell lines, also lengthened it in-central clock tissues and peripheral clock cells. Most compounds inhibited casein kinase Iε (CKIε) or CKIδ phosphorylation of the PER2 protein. Manipulation of CKIε/δ-dependent phosphorylation by these compounds lengthened the period of the mammalian clock from circadian (24 h) to circabidian (48 h), revealing its high sensitivity to chem. perturbation. The degradation rate of PER2, which is regulated by CKIε/δ-dependent phosphorylation, was temperature-insensitive in living clock cells, yet sensitive to chem. perturbations. This temperature-insensitivity was preserved in the CKIε/δ-dependent phosphorylation of a synthetic peptide in vitro. Thus, CKIε/δ-dependent phosphorylation is likely a temperature-insensitive period-determining process in the mammalian circadian clock.
