DEC2 modulates orexin expression and regulates sleep. [PDF]
, 2018 Adequate sleep is essential for physical and mental health. We previously identified a missense mutation in the human DEC2 gene (BHLHE41) leading to the familial natural short sleep behavioral trait.

The non-JAZ TIFY protein TIFY8 from Arabidopsis thaliana is a transcriptional repressor.
PLoS ONE, 2014 Jasmonate (JA) signalling is mediated by the JASMONATE-ZIM DOMAIN (JAZ) repressor proteins, which are degraded upon JA perception to release downstream responses. The ZIM protein domain is characteristic of the larger TIFY protein family. It is currently

Genome-Wide Identification, Functional Analysis and Expression Profiling of the Aux/IAA Gene Family in Tomato [PDF]
, 2012 Auxin is a central hormone that exerts pleiotropic effects on plant growth including the development of roots, shoots, flowers and fruit. The perception and signaling of the plant hormone auxin rely on the cooperative action of several components,among

Modular Organization of the Phd Repressor/Antitoxin Protein [PDF]
Journal of Bacteriology, 2004 ABSTRACT The P1 plasmid addiction operon is a compact genetic structure consisting of promoter, operator, antitoxin gene ( phd ), and toxin gene ( doc ). The 73-amino-acid antitoxin protein, Phd, has two distinct functions: it represses transcription (by binding to its operator) and

Microbiology Spectrum, 2023 Stl, the master repressor of the Staphylococcus aureus pathogenicity islands (SaPIs), targets phage-encoded proteins to derepress and synchronize the SaPI and the helper phage life cycles. To activate their cycle, some SaPI Stls target both phage dimeric

Optimizing periodicity and polymodality in noise-induced genetic oscillators [PDF]
, 2011 Many cellular functions are based on the rhythmic organization of biological processes into self-repeating cascades of events. Some of these periodic processes, such as the cell cycles of several species, exhibit conspicuous irregularities in the form of

I. Biosynthesis of a Repressor/Nuclease Hybrid Protein
Journal of Biological Chemistry, 1989 The phage T7 endonuclease gene was fused to the 3' end of the lac repressor gene. The hybrid protein exhibits repressor and nuclease functions in a manner dependent on the conformation of the DNA. With supercoiled DNA, nuclease activity is directed to the major cruciform, whereas with linear DNA, the enzyme cleaves preferentially restriction fragments ...

ArgR is an essential local transcriptional regulator of the arcABC-operon in Streptococcus suis and crucial for biological fitness in acidic environment [PDF]
, 2011 Streptococcus suis is one of the most important pathogens in pigs and can also cause severe infections in humans. Despite its clinical relevance very little is known about the factors contributing to its virulence.

Cells, 2021 Numerous genes are overexpressed in the radioresistant bacterium Deinococcus radiodurans after exposure to radiation or prolonged desiccation. It was shown that the DdrO and IrrE proteins play a major role in regulating the expression of approximately ...
