Adaptive Responses by Transcriptional Regulators to Small Molecules in Prokaryotes
Adaptive Responses by Transcriptional Regulators to small molecules in Prokaryotes Structural studies of two bacterial one-component signal transduction systems DntR and HpNikR Cyril Dian Stockholm University Doctoral thesis © Cyril Dian, Stockholm 2007 ISBN 978-91-7155-500-7 Department of Biochemistry and Biophysics The Arrhenius Laboratories for Natural Sciences Stockholm University SE-106 91 Stockholm Sweden All previously published papers are reprinted With permission from the publishers Intellecta Docusys, Stockholm 2007 Abstract Prokaryotes are continually exposed to environmental changes in their physiological conditions. In order to survive such unstable conditions, or to compete with others species for the same environmental niche, prokaryotes must monitor signals about both their extracellular environment and intracellular physiological status and provide rapid and appropriate responses to variations in their surroundings. This adaptive response to environmental signals is triggered mainly by transcriptional regulators via two components, the one- and two-component signal transduction systems. These scan intra- and extracellular small-molecule mixtures and modulate gene expression to provide the appropriate physiological response to the prevailing conditions. Most prokaryotic one component regulators are simple transcription factors comprising of a small-molecule binding domain (SMBD) and a DNA binding domain (DBD). Although the effects of transcription factors on the transcription machinery are well understood, the exact location -

Johnsen Received: 25 August 2020 / Revised: 3 February 2021 / Accepted: 4 February 2021 / Published online: 3 March 2021 © The Author(s) 2021. This article is published with open access Abstract Esophageal squamous cell carcinoma (ESCC) is the predominant subtype of esophageal cancer with a particularly high prevalence in certain geographical regions and a poor prognosis with a 5-year survival rate of 15–25%. Despite numerous studies characterizing the genetic and transcriptomic landscape of ESCC, there are currently no effective targeted therapies. In this study, we used an unbiased screening approach to uncover novel molecular precision oncology targets for ESCC and identified the bromodomain and extraterminal (BET) family member bromodomain testis-specific protein (BRDT) to be 1234567890();,: 1234567890();,: uniquely expressed in a subgroup of ESCC. Experimental studies revealed that BRDT expression promotes migration but is dispensable for cell proliferation. Further mechanistic insight was gained through transcriptome analyses, which revealed that BRDT controls the expression of a subset of ΔNp63 target genes. Epigenome and genome-wide occupancy studies, combined with genome-wide chromatin interaction studies, revealed that BRDT colocalizes and interacts with ΔNp63 to drive a unique transcriptional program and modulate cell phenotype. Our data demonstrate that these genomic regions are enriched for super-enhancers that loop to critical ΔNp63 target genes related to the squamous phenotype such as KRT14, FAT2, and PTHLH. -

Protein Interactions with the Glucose Transporter Binding Protein GLUT1CBP That Provide a Link Between GLUT1 and the Cytoskeleton Robert C
Molecular Biology of the Cell Vol. 10, 819–832, April 1999 Protein Interactions with the Glucose Transporter Binding Protein GLUT1CBP That Provide a Link between GLUT1 and the Cytoskeleton Robert C. Bunn, Mari Anne Jensen, and Brent C. Reed* The Department of Biochemistry and Molecular Biology, Louisiana State University School of Medicine, Shreveport, Louisiana 71130-3932 Submitted October 27, 1998; Accepted January 19, 1999 Monitoring Editor: Guido Guidotti Subcellular targeting and the activity of facilitative glucose transporters are likely to be regulated by interactions with cellular proteins. This report describes the identification and characterization of a protein, GLUT1 C-terminal binding protein (GLUT1CBP), that binds via a PDZ domain to the C terminus of GLUT1. The interaction requires the C-terminal four amino acids of GLUT1 and is isoform specific because GLUT1CBP does not interact with the C terminus of GLUT3 or GLUT4. Most rat tissues examined contain both GLUT1CBP and GLUT1 mRNA, whereas only small intestine lacked detectable GLUT1CBP protein. GLUT1CBP is also expressed in primary cultures of neurons and astrocytes, as well as in Chinese hamster ovary, 3T3-L1, Madin–Darby canine kidney, Caco-2, and pheochromocytoma-12 cell lines. GLUT1CBP is able to bind to native GLUT1 extracted from cell membranes, self-associate, or interact with the cytoskeletal proteins myosin VI, a-actinin-1, and the kinesin superfamily protein KIF-1B. The presence of a PDZ domain places GLUT1CBP among a growing family of structural and regulatory proteins, many of which are localized to areas of membrane specialization. This and its ability to interact with GLUT1 and cytoskeletal proteins implicate GLUT1CBP in cellular mechanisms for targeting GLUT1 to specific subcellular sites either by tethering the transporter to cytoskeletal motor proteins or by anchoring the transporter to the actin cytoskeleton. -
