Stochastic models and numerical algorithms for a class of regulatory gene networks [PDF]

open access: yes, 2008
Regulatory gene networks contain generic modules like those involving feedback loops, which are essential for the regulation of many biological functions.

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.

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 ...

Nonlinear software sensor for monitoring genetic regulation processes with noise and modeling errors

open access: yes, 2004
Nonlinear control techniques by means of a software sensor that are commonly used in chemical engineering could be also applied to genetic regulation processes.

CopY-like Copper Inducible Repressors are Putative ‘Winged Helix’ Proteins [PDF]

open access: yesBiometals, 2006
CopY of Enterococcus hirae is a well characterized copper-responsive repressor involved in copper homeostasis. In the absence of copper, it binds to the promoter. In high copper, the CopZ copper chaperone donates copper to CopY, thereby releasing it from the promoter and allowing transcription of the downstream copper homeostatic genes of the cop ...

The short-lived MATα2 transcriptional regulator is ubiquitinated in vivo [PDF]

open access: yes, 1991
The substrates of ubiquitin-dependent proteolytic pathways include both damaged or otherwise abnormal proteins and undamaged proteins that are naturally short-lived. Few specific examples of the latter class have been identified, however.

Designer Gene Networks: Towards Fundamental Cellular Control

open access: yes, 2001
The engineered control of cellular function through the design of synthetic genetic networks is becoming plausible. Here we show how a naturally occurring network can be used as a parts list for artificial network design, and how model formulation leads ...

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

Revisiting Allostery in the Lac Repressor Protein [PDF]

open access: yesBiophysical Journal, 2015
The lac repressor protein (lac) is an allosterically regulated transcription factor which controls expression of the lac operon in bacteria. Binding of a small molecule inducer to a site 40A away from the DNA-binding domain relieves repression through what is thought to be local unfolding of the hinge helix.
