Publication Abstract from PubMedThe kinase DOUBLETIME is a master regulator of the Drosophila circadian clock, yet the mechanisms regulating its activity remain unclear. A proteomic analysis of DOUBLETIME interactors led to the identification of an unstudied protein designated CG17282. RNAi-mediated knockdown of CG17282 produced behavioral arrhythmicity and long periods and high levels of hypophosphorylated nuclear PERIOD and phosphorylated DOUBLETIME. Overexpression of DOUBLETIME in flies suppresses these phenotypes and overexpression of CG17282 in S2 cells enhances DOUBLETIME-dependent PERIOD degradation, indicating that CG17282 stimulates DOUBLETIME's circadian function. In photoreceptors, CG17282 accumulates rhythmically in PERIOD- and DOUBLETIME-dependent cytosolic foci. Finally, structural analyses demonstrated CG17282 is a noncanonical FK506-binding protein with an inactive peptide prolyl-isomerase domain that binds DOUBLETIME and tetratricopeptide repeats that may promote assembly of larger protein complexes. We have named CG17282 BRIDE OF DOUBLETIME and established it as a mediator of DOUBLETIME's effects on PERIOD, most likely in cytosolic foci that regulate PERIOD nuclear accumulation.
