Purification and Characterisation of the Repressor Proteins from the Streptomyces Bacteriophage OC31 [PDF]

open access: yes, 1993
OC31 is a bacteriophage of Streptomyces species in which it undergoes a lysogenic life-cycle. The phage possesses a 41.5kb genome and cohesive ends. The lysogenic phase of development is regulated by the repressor gene (c) which lies in the centre of the

Two-Hybrid System for Characterization of Protein-Protein Interactions in E. coli

open access: yesBioTechniques, 2000
The yeast two-hybrid system has been used to characterize many protein-protein interactions. A two-hybrid system for E. coli was constructed in which one hybrid protein bound to a specific DNA site recruits another to an adjacent DNA binding site.

Spatial epigenetic control of mono- and bistable gene expression. [PDF]

open access: yesPLoS Biology, 2010
Bistability in signaling networks is frequently employed to promote stochastic switch-like transitions between cellular differentiation states. Differentiation can also be triggered by antagonism of activators and repressors mediated by epigenetic ...

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

open access: yesJournal 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 ...

Regulation of Dpp target genes by Mad/Medea and Brinker [PDF]

open access: yes, 2009
The TGF-β family member Decapentaplegic (Dpp) is a key regulator of patterning and growth in development of Drosophila. Binding of Dpp to its receptors triggers the activation of the intracellular Smad pathway.

The non-JAZ TIFY protein TIFY8 from Arabidopsis thaliana is a transcriptional repressor.

open access: yesPLoS 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

I. Biosynthesis of a Repressor/Nuclease Hybrid Protein

open access: yesJournal 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 ...

The STAR protein QKI-6 is a translational repressor [PDF]

open access: yesProceedings of the National Academy of Sciences, 1999
The signal transduction and activation of RNA (STAR) family of RNA-binding proteins, whose members are evolutionarily conserved from yeast to humans, are important for a number of developmental decisions. For example, in the mouse, quaking proteins (QKI-5, QKI-6, and QKI-7) are essential for ...

The Bacteriophage–Phage-Inducible Chromosomal Island Arms Race Designs an Interkingdom Inhibitor of dUTPases

open access: yesMicrobiology 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

Modular Organization of the Phd Repressor/Antitoxin Protein [PDF]

open access: yesJournal 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
