Here we demonstrate that the transcription factor CLOCKWORK ORANGE (CWO) antagonizes CLK-CYC (Montrer COX6C Kits ELISA) E-box binding, thus enhancing the removal of CLK-CYC (Montrer COX6C Kits ELISA) from E-boxes to maintain transcriptional repression. This process requires PER, which suggests that PER-TIM and CWO cooperate to maintain a transcriptionally repressed state by removing CLK-CYC (Montrer COX6C Kits ELISA) from E-boxes

usp8 (Montrer USP8 Kits ELISA) loss of function (RNAi) or expression of a dominant-negative form of the protein (USP8 (Montrer USP8 Kits ELISA)-DN) enhances CLK/CYC (Montrer COX6C Kits ELISA) transcriptional activity and alters fly locomotor activity rhythms
CLK has specific targets in different tissues, implying that important CLK partner proteins and/or mechanisms contribute to gene-specific and tissue-specific regulation
CTRIP destabilizes CLK protein in a PER-independent manner and helps degradation of phosphorylated PER and TIM in the morning
dPER(DeltaCBD) does not provoke the daily hyperphosphorylation of dCLOCK, indicating that direct interactions between dPER and dCLOCK are necessary for the dCLOCK phosphorylation
findings show that Clk and cyc (Montrer COX6C Kits ELISA) act during starvation to modulate the conflict of whether flies sleep or search for food
Data suggest that Clock1a coordinates mesoderm development and primitive hematopoiesis in embryos by up-regulating Nodal-Smad3 (Montrer SMAD3 Kits ELISA) signaling; Clock1a alterations produce embryonic defects with shortened body length, lack of ventral tail fin, or partial defect of the eyes; Clock1a activates Smad3a (Montrer SMAD3 Kits ELISA) promoter via its E-box1 element. (Clock1a = clock circadian regulator a; Nodal = nodal modulator 1 (Montrer NOMO1 Kits ELISA); Smad3a (Montrer SMAD3 Kits ELISA) = SMAD (Montrer SMAD1 Kits ELISA) family member 3a)
effect of CRY (Montrer CRY2 Kits ELISA) in repressing transcription mediated by CLOCK-BMAL heterodimer
ASS1 (Montrer ASS1 Kits ELISA) acetylation by CLOCK exhibits circadian oscillation in human cells and mouse liver, possibly caused by rhythmic interaction between CLOCK and ASS1 (Montrer ASS1 Kits ELISA), leading to the circadian regulation of ASS1 (Montrer ASS1 Kits ELISA) and ureagenesis.
Disruption of CLOCK protein (Montrer ARNTL Kits ELISA) alters cortical circuits and leads to generation of focal epilepsy.
Development of Mineralocorticoid receptor (Montrer NR3C2 Kits ELISA)-mediated cardiac inflammation and fibrosis is dependent on intact signaling by the circadian protein CLOCK.

These results suggest that bone resorption and bone mass are regulated at a sophisticated level by osteoblastic Clock system through a mechanism relevant to the modulation of 1,25(OH)2 D3 -induced Rankl (Montrer TNFSF11 Kits ELISA) expression in osteoblasts.
Abundance of CDH1 (Montrer CDH1 Kits ELISA) and TP63 (Montrer TP63 Kits ELISA) proteins were significantly reduced in cultures transfected with shClock These data support how CLOCK plays a role in regulation of epithelial cell growth and differentiation in the mammary gland.
Data demonstrate that CLOCK and BMAL1 (Montrer ARNTL Kits ELISA) regulate muscle insulin (Montrer INS Kits ELISA) sensitivity via SIRT1 (Montrer SIRT1 Kits ELISA), and activation of SIRT1 (Montrer SIRT1 Kits ELISA) might be a potential valuable strategy to attenuate muscle insulin (Montrer INS Kits ELISA) resistance related to circadian misalignment.
These data establish the importance of circadian CLOCK-inhibin signaling in sepsis.
Our findings suggest that CLOCK and CRY1 polymorphisms might be involved in individual susceptibility to abdominal obesity in Chinese Han population.
This study showed that Lack of Association between Genetic Polymorphism of clock gene with Late Onset Depression and Alzheimer's Disease in a Sample of a Brazilian Population This study showed that Lack of Association between Genetic Polymorphism of PER2 (Montrer PER2 Kits ELISA) gene with Late Onset Depression and Alzheimer's Disease in a Sample of a Brazilian Population

Clock circadian regulator (CLOCK) gene single nucleotide polymorphism rs1801260 minor allele C showed a significantly higher association with the prevalence of diabetes in the Japanese population independent of body mass index (BMI).
Immunostaining of CLOCK and PER2 (Montrer PER2 Kits ELISA) protein was detected in the granulosa cells of dominant antral follicles but was absent in the primordial, primary, or preantral follicles of human ovaries.Oscillating expression of the circadian gene PER2 (Montrer PER2 Kits ELISA) can be induced by testosterone in human granulosa cells in vitro. Expression of STAR also displayed an oscillating pattern after testosterone stimulation

Upregulation of CLOCK is associated with the expression of HIF-1alpha and VEGF in varicose veins.
when overexpressed, c-MYC (Montrer MYC Kits ELISA) is able to repress Per1 (Montrer PER1 Kits ELISA) transactivation by BMAL1 (Montrer ARNTL Kits ELISA)/CLOCK via targeting selective E-box sequences.

the second half of the photolyase homology region (PHR) of CRY (Montrer CRY2 Kits ELISA) is important for repression through facilitating interaction with CLOCK
This gene product regulates circadian rhythm and metabolism. The protein encodes a transcription factor of the basic helix-loop-helix (bHLH) family and a DNA binding histone acetyltransferase. Polymorphisms in this gene may be associated with behavioral changes in certain populations and with obesity and metabolic syndrome. Alternative splicing results in multiple transcript variants.
