YgaE Regulates Out Membrane Proteins in Salmonella enterica Serovar Typhi under Hyperosmotic Stress

The Scientific World Journal, 2014
Salmonella enterica serovar Typhi (S. Typhi) is a human-specific pathogen that causes typhoid fever. In this study, we constructed ΔygaE mutant and a microarray was performed to investigate the role of ygaE in regulation of gene expression changes in ...

Evidence That Runt Acts as a Counter-Repressor of Groucho During Drosophila melanogaster Primary Sex Determination

G3: Genes, Genomes, Genetics, 2020
Runx proteins are bifunctional transcription factors that both repress and activate transcription in animal cells. Typically, Runx proteins work in concert with other transcriptional regulators, including co-activators and co-repressors to mediate their ...

Genomic characterization of Gli-activator targets in sonic hedgehog-mediated neural patterning [PDF]

, 2007
Sonic hedgehog (Shh) acts as a morphogen to mediate the specification of distinct cell identities in the ventral neural tube through a Gli-mediated (Gli1-3) transcriptional network.

Chemical synthesis of a fully active transcriptional repressor protein. [PDF]

Proceedings of the National Academy of Sciences, 1994
Plasmid pLS1-encoded 45-amino acid transcriptional repressor CopG (formerly RepA) has been chemically synthesized. A one-step purification of the synthetic protein has been developed, which yields high levels of pure protein with low or no contamination of truncated products.

Conserved structural motifs in PAS, LOV, and CRY proteins regulate circadian rhythms and are therapeutic targets

FEBS Letters, EarlyView.
Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.

Auxin-sensitive Aux/IAA proteins mediate drought tolerance in Arabidopsis by regulating glucosinolate levels

Nature Communications, 2019
Brassicaceae produce glucosinolates to protect against herbivory and pathogens. Here the authors show that auxin-sensitive Aux/IAA repressor proteins regulate aliphatic glucosinolate levels in Arabidopsis and this promotes stomatal closure via reactive ...

Sequence Dependence of Transcription Factor-Mediated DNA Looping [PDF]

, 2012
DNA is subject to large deformations in a wide range of biological processes. Two key examples illustrate how such deformations influence the readout of the genetic information: the sequestering of eukaryotic genes by nucleosomes, and DNA looping in ...

The c1 repressor of bacteriophage P1. Isolation and characterization of the repressor protein.

Journal of Biological Chemistry, 1988
The c1 repressor gene of bacteriophage P1 is located on P1 DNA EcoRI fragment 7 (Sternberg, N. (1979) Virology 96, 129-142). Subfragments of P1 DNA EcoRI fragment 7 were cloned into expression vectors, and the c1 repressor protein from P1 wild-type phage and a revertant of a temperature-sensitive repressor mutant were overproduced in Escherichia coli ...

The transcriptional repressor protein PRH interacts with the proteasome [PDF]

Biochemical Journal, 2003
PRH (proline-rich homeodomain protein)/Hex is important in the control of cell proliferation and differentiation. We have shown previously that PRH contains two domains that can bring about transcriptional repression independently; the PRH homeodomain represses transcription by binding to TATA box sequences, whereas the proline-rich N-terminal domain ...

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

FEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.
