Insertion of 643bp Retrotransposon Upstream of PPARγ CDS Is Associated with Backfat of Large White Pigs

Animals, 2023
PPARs are essential regulators of mammalian fatty acid and lipid metabolism. Although the effects of genetic variations, including single nucleotide polymorphisms (SNPs) in PPARs genes on the phenotype of domestic animals have been investigated, there is

MrMYB6 From Chinese Bayberry (Myrica rubra) Negatively Regulates Anthocyanin and Proanthocyanidin Accumulation

Frontiers in Plant Science, 2021
Anthocyanins and proanthocyanidins (PAs) are important flavonoids in Chinese bayberry (Morella rubra), which functions in fruit color and exhibits multiple health promoting and disease-preventing effects.

Rules of Expansion: an Updated Consensus Operator Site for the CopR-CopY Family of Bacterial Copper Exporter System Repressors

mSphere, 2020
Copper is broadly toxic to bacteria. As such, bacteria have evolved specialized copper export systems (cop operons) often consisting of a DNA-binding/copper-responsive regulator (which can be a repressor or activator), a copper chaperone, and a copper ...

Role of the purine repressor hinge sequence in repressor function [PDF]

Journal of Bacteriology, 1994
A protease-hypersensitive hinge sequence in Escherichia coli purine repressor (PurR) connects an N-terminal DNA-binding domain with a contiguous corepressor-binding domain. Binding of one molecule of dimeric repressor to operator DNA protects the hinge against proteolytic cleavage.

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.

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.

An enhanced CRISPR repressor for targeted mammalian gene regulation. [PDF]

, 2018
The RNA-guided endonuclease Cas9 can be converted into a programmable transcriptional repressor, but inefficiencies in target-gene silencing have limited its utility.
