Genome-Wide Characterization of R2R3-MYB Transcription Factors in Pitaya Reveals a R2R3-MYB Repressor HuMYB1 Involved in Fruit Ripening through Regulation of Betalain Biosynthesis by Repressing Betalain Biosynthesis-Related Genes

Cells, 2021
The MYB (myeloblastosis) superfamily constitutes one of the most abundant transcription factors (TFs) regulating various biological processes in plants. However, the molecular characteristics and functions of MYB TFs in pitaya remain unclear. To date, no

CrgA Protein Represses AlkB2 Monooxygenase and Regulates the Degradation of Medium-to-Long-Chain n-Alkanes in Pseudomonas aeruginosa SJTD-1

Frontiers in Microbiology, 2019
AlkB monooxygenases in bacteria are responsible for the hydroxylation of medium- and long-chain n-alkanes. In this study, one CrgA protein of Pseudomonas aeruginosa SJTD-1, a member of LysR family, was proved to regulate AlkB2 monooxygenase and the ...

The KRAB Domain‐Containing Protein ZFP961 Represses Adipose Thermogenesis and Energy Expenditure through Interaction with PPARα

Advanced Science, 2022
Adipose thermogenesis plays a pivotal role in whole‐body metabolic homeostasis. Although transcriptional mechanisms that promote thermogenesis are extensively studied, the negative regulatory network is still poorly understood. Here, a Krüppel‐associated

Multiple binding sites for transcriptional repressors can produce regular bursting and enhance noise suppression [PDF]

, 2017
Cells may control fluctuations in protein levels by means of negative autoregulation, where transcription factors bind DNA sites to repress their own production.

Profiling of REST-dependent microRNAs reveals dynamic modes of expression

Frontiers in Neuroscience, 2012
Multipotent neural stem cells (NSCs) possess the ability to self-renew and differentiate into both neurons and glia. However, the detailed mechanisms underlying NSC fate decisions are not well understood.

A Gain-of-Function Mutant of IAA15 Inhibits Lateral Root Development by Transcriptional Repression of LBD Genes in Arabidopsis

Frontiers in Plant Science, 2020
Lateral root development is known to be regulated by Aux/IAA-ARF modules in Arabidopsisthaliana. As components, several Aux/IAAs have participated in these Aux/IAA-ARF modules.

Nucleotide sequence and mutational analysis of an immunity repressor gene from Bacillus subtilis temperate phage ϕ105 [PDF]

, 1985
We have identified and sequenced a bacteriophage phi 105 gene encoding an immunity repressor, the first to be characterized from a temperate phage infecting a Gram-positive host.

Isolating intrinsic noise sources in a stochastic genetic switch [PDF]

, 2011
The stochastic mutual repressor model is analysed using perturbation methods. This simple model of a gene circuit consists of two genes and three promotor states. Either of the two protein products can dimerize, forming a repressor molecule that binds to

The GbsR Family of Transcriptional Regulators: Functional Characterization of the OpuAR Repressor

Frontiers in Microbiology, 2018
Accumulation of compatible solutes is a common stress response of microorganisms challenged by high osmolarity; it can be achieved either through synthesis or import.

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 ...
