Repressor element-1 silencing transcription/neuron-restrictive silencer factor is required for neural sodium channel expression during development of Xenopus
(2002)
The ability of neurons to fire rapid action potential relies on the expression of voltage-gated sodium channels; the onset of the transcription of genes that encode these channels occurs during early neuronal development. ...
The Wnt-activated Xiro1 gene encodes a repressor that is essential for neural development and downregulates Bmp4
(Company of Biologists Ltd, 2001)
In the early Xenopus embryo, the Xiro homeodomain proteins of the Iroquois (Iro) family control the expression of proneural genes and the size of the neural plate. We report that Xiro1 functions as a repressor that is ...
Regulation of carotenogenesis in the red yeast Xanthophyllomyces dendrorhous: the role of the transcriptional co-repressor complex Cyc8-Tup1 involved in catabolic repression
(Biomed Central, 2016)
Background: The yeast Xanthophyllomyces dendrorhous produces carotenoids of commercial interest, including astaxanthin and beta-carotene. Although carotenogenesis in this yeast and the expression profiles of the genes ...
Expression of carotenogenic genes in mutant strains for two general transcriptional repressors in the yeast Xanthophyllomyces dendrorhous
(2015)
Introduction
Xanthophyllomyces dendrorhous is a carotenogenic yeast producer of astaxanthin, pigment of commercial
interest due to its use in aquaculture and pharmaceutical industries. Currently, it is known the ...
Canonical P elements are transcriptionally active in the saltans group of Drosophila
(2004-07-01)
Up to now, investigations of expression and regulation of P transposable element have been almost exclusively carried out with the Drosophila melanogaster canonical P element. Analyzing eight species of the saltans group, ...

Multiple binding sites for transcriptional repressors can produce regular bursting and enhance noise suppression
(American Physical Society, 2017-04)
Cells may control fluctuations in protein levels by means of negative autoregulation, where transcription factors bind DNA sites to repress their own production. Theoretical studies have assumed a single binding site for ...
A single P115Q mutation modulates specificity in the Corynebacterium pseudotuberculosis arginine repressor
(2020-07-01)
The arginine repressor (ArgR) regulates the expression of genes involved in arginine biosynthesis. Upon attaining a threshold concentration of arginine in the cytoplasm, the trimeric C-terminal domain of ArgR binds three ...
