Role of the unique N-terminal domain of CtBP2 in determining the subcellular localisation of CtBP family proteins [PDF]

open access: yes, 2006
BACKGROUND: CtBP1 and CtBP2 are transcriptional co-repressors that modulate the activity of a large number of transcriptional repressors via the recruitment of chromatin modifiers.

Myb‐like transcription factors have epistatic effects on circadian clock function but additive effects on plant growth

open access: yesPlant Direct, 2023
The functions of closely related Myb‐like repressor and Myb‐like activator proteins within the plant circadian oscillator have been well‐studied as separate groups, but the genetic interactions between them are less clear.

Cholesterol, a repressor of natriuretic proteins

open access: yesThe FASEB Journal, 2019
Salt‐sensitivity in Dahl rats is due, in part, to the reduction of hemoxygenase‐1 (HO1), cyclooxygenase 2 (COX2), and nitric oxide synthase‐2 (NOS2) in the renal medulla. Renal overexpression of HIF1‐α, a regulator of HO1, COX2, and NOS2, enhances salt and water excretion and reduces blood pressure. Cholesterol (chol) incorporation into collecting duct

Direct observation of dimerization between different CREB1 isoforms in a living cell. [PDF]

open access: yesPLoS ONE, 2011
Cyclic AMP-responsive element binding protein 1 (CREB1) plays multiple functions as a transcription factor in gene regulation. CREB1 proteins are also known to be expressed in several spliced isoforms that act as transcriptional activators or repressors.

Characterization of the Radiation Desiccation Response Regulon of the Radioresistant Bacterium Deinococcus radiodurans by Integrative Genomic Analyses

open access: yesCells, 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 ...

Liver organoids: modelling complexity in homeostasis and disease

open access: yesFEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

Characterization of multifunctional proteins from Helicobacter pylori [PDF]

open access: yes, 2010
This thesis reports the cloning, overexpression and characterization of two interesting proteins from Helicobacter pylori: Heat Shock protein A (HspA), and CoaX (Type III Pantothenate kinase).

Repressor fusions as a tool to study protein–protein interactions [PDF]

open access: yesStructure, 1995
Genetic reporter systems are necessarily limited in the kinds of information they can provide. The most obvious limitation is that the insides of cells are complex. The phenotype of a gene fusion protein will be determined not only by the property we wish to assay, but also by other effects of the intracellular environment on the chimeric gene product,

A Repressor Protein Complex Regulates Leaf Growth in Arabidopsis [PDF]

open access: yesThe Plant Cell, 2015
Cell number is an important determinant of final organ size. In the leaf, a large proportion of cells are derived from the stomatal lineage. Meristemoids, which are stem cell-like precursor cells, undergo asymmetric divisions, generating several pavement cells adjacent to the two guard cells.

Repressor dimerization in the zebrafish somitogenesis clock [PDF]

open access: yes, 2007
The oscillations of the somitogenesis clock are linked to the fundamental process of vertebrate embryo segmentation, yet little is known about their generation.
