How a Circadian Clock Adapts to Seasonal Decreases in Temperature and Day Length
We show that a thermosensitive splicing event in the 3' untranslated region of the mRNA from the period (per) gene plays an important role in how a circadian clock in Drosophila adapts to seasonallyExpand

Circadian Regulation of a Drosophila Homolog of the Mammalian Clock Gene: PER and TIM Function as Positive Regulators
ABSTRACT The Clock gene plays an essential role in the manifestation of circadian rhythms (≅24 h) in mice and is a member of the basic helix-loop-helix (bHLH) PER-ARNT-SIM (PAS) superfamily ofExpand

Structure of the Staphylococcus aureus AgrA LytTR domain bound to DNA reveals a beta fold with an unusual mode of binding.
The LytTR domain is a DNA-binding motif found within the AlgR/AgrA/LytR family of transcription factors that regulate virulence factor and toxin gene expression in pathogenic bacteria. ThisExpand

Integrative analysis of chromatin states in Arabidopsis identified potential regulatory mechanisms for natural antisense transcript production.
Genome-wide analyses of epigenomic and transcriptomic profiles provide extensive resources for discovering epigenetic regulatory mechanisms. However, the construction of functionally relevantExpand

Differential Effects of Light and Heat on theDrosophila Circadian Clock Proteins PER and TIM
ABSTRACT Circadian (≅24-h) rhythms are governed by endogenous biochemical oscillators (clocks) that in a wide variety of organisms can be phase shifted (i.e., delayed or advanced) by brief exposureExpand

Structural basis for RNA duplex recognition and unwinding by the DEAD-box helicase Mss116p
DEAD-box proteins are the largest family of nucleic acid helicases, and are crucial to RNA metabolism throughout all domains of life. They contain a conserved ‘helicase core’ of two RecA-like domainsExpand

Direct CRISPR spacer acquisition from RNA by a natural reverse transcriptase–Cas1 fusion protein
CRISPR-Cas captures invading RNA The CRISPR (clustered regularly interspaced short palindromic repeat) system provides bacteria with an adaptive immune response. DNA captured from viruses andExpand

Identification of a hydrophobic cleft in the LytTR domain of AgrA as a locus for small molecule interactions that inhibit DNA binding.
The AgrA transcription factor regulates the quorum-sensing response in Staphylococcus aureus, controlling the production of hemolysins and other virulence factors. AgrA binds to DNA via itsExpand

NMR structure of an archaeal homologue of ribonuclease P protein Rpp29.
A protein component of the Archaeoglobus fulgidus RNase P was expressed in Escherichia coli, purified, and structurally characterized using multidimensional NMR methods. The dominant structuralExpand

Enhanced group II intron retrohoming in magnesium-deficient Escherichia coli via selection of mutations in the ribozyme core
Significance Mobile group II introns are bacterial retrotransposons. They consist of an autocatalytic intron RNA (“ribozyme”) and an intron-encoded reverse transcriptase and were likely ancestors ofExpand
