(Submitter supplied) The spliceosome is a dynamic RNA-protein complex that executes pre-mRNA splicing and is composed of five core small nuclear ribonucleoprotein particles (U1, U2, U4/5/6 snRNP) and >150 additional proteins specific for each snRNP. We report a circadian role for Pre-mRNA Processing factor 4 (PRP4), a conserved component of the spliceosomal U4/U6.U5 triple small nuclear ribonucleoprotein (tri-snRNP) complex. more...

(Submitter supplied) Circadian clocks are temporally aligned to the environment via signals, or Zeitgebers, such as daily light and temperature cycles, food availability, and social behavior. In this study, we show that genome-wide expression profiles from temperature-entrained flies show a dramatic difference in the presence or absence of a thermocycle. Whereas transcription appears to be modified globally by changes in temperature, there is a specific set of transcripts that continue to oscillate in constant conditions following temperature entrainment. more...

(Submitter supplied) To address the contribution of transcriptional regulation to Drosophila clock gene expression and to behavior, we generated a series of CRISPR-mediated deletions within two regions of the circadian gene timeless (tim), an intronic E box region and an upstream E box region that are both recognized by the key transcription factor Clock (Clk) and its heterodimeric partner Cycle. The upstream deletions but not an intronic deletion dramatically impact tim expression in fly heads; the biggest upstream deletion reduces peak RNA levels and tim RNA cycling amplitude to about 15% of normal, and there are similar effects on tim protein (TIM). more...

(Submitter supplied) The contribution of cis-regulatory elements to Drosophila circadian gene expression is poorly understood. We generated a series of CRISPR-mediated deletions within the regulatory regions of the circadian gene timeless (tim) and characterized them through multiple high-throughput sequencing experiments. We isolated heads from wild-type and mutant flies around the clock and performed RNA-Seq on them to determine the effects of regulatory element deletions on circadian gene expression.

(Submitter supplied) Eukaryotic circadian clocks include transcriptional/translational feedback loops that drive 24-hour rhythms of transcription.These transcriptional rhythms underlie oscillations of protein abundance, thereby mediating circadian rhythms of behavior, physiology, and metabolism. Numerous studies over the last decade have employed microarrays to profile circadian transcriptional rhythms in various organisms and tissues. more...

(Submitter supplied) Single microRNAs are usually associated with hundreds of putative target genes that can influence multiple phenotypic traits in Drosophila, ranging from development to behaviour. We investigated the function of Drosophila miR-210 in circadian behaviour by misexpressing it within circadian clock cells. Manipulation of miR-210 expression levels in the PDF (pigment dispersing factor) positive neurons affected the phase of locomotor activity, under both light-dark conditions and constant darkness. more...

(Submitter supplied) MicroRNAs (miRNAs) are a novel class of small RNAs which act as modulators of gene expression either by inhibiting the translation or by inducing the degradation of their target mRNAs. Several studies suggest a role for miRNAs as regulators of the circadian clock in mammals and Drosophila. Based on computational predictions of target mRNAs of clock (or clock related) genes, we have selected the miR-210 as a putative regulator of the period clock gene. more...
