HSF2 autoregulates its own transcription.
Heat shock factor 2 (HSF2) is one of the most important regulators affecting stress mechanisms, and is frequently amplified in the ubiquitin proteasome pathway. Despite its significance, the mechanisms which regulate HSF2 expression remain unclear. In the present study, we describe the existence of a negative autoregulatory mechanism of HSF2. Transfection assays demonstrated that HSF2 decreased...
متن کاملMycobacterium tuberculosis FurA autoregulates its own expression.
The furA-katG region of Mycobacterium tuberculosis, encoding a Fur-like protein and the catalase-peroxidase, is highly conserved among mycobacteria. Both genes are induced upon oxidative stress. In this work we analyzed the M. tuberculosis furA promoter region. DNA fragments were cloned upstream of the luciferase reporter gene, and promoter activity in Mycobacterium smegmatis was measured in bo...
متن کاملProhepcidin binds to the HAMP promoter and autoregulates its own expression.
Hepcidin is the major regulatory peptide hormone of iron metabolism, encoded by the HAMP (hepcidin antimicrobial peptide) gene. Hepcidin is expressed mainly in hepatocytes, but is also found in the blood in both a mature and prohormone form. Although, the function of mature hepcidin and the regulation of the HAMP gene have been extensively studied, the intracellular localization and the fate of...
متن کاملTrichoderma atroviride PHR1, a fungal photolyase responsible for DNA repair, autoregulates its own photoinduction.
The photolyases, DNA repair enzymes that use visible and long-wavelength UV light to repair cyclobutane pyrimidine dimers (CPDs) created by short-wavelength UV, belong to the larger photolyase-cryptochrome gene family. Cryptochromes (UVA-blue light photoreceptors) lack repair activity, and sensory and regulatory roles have been defined for them in plants and animals. Evolutionary considerations...
متن کاملThe product of varicella-zoster virus gene 62 autoregulates its own promoter.
Varicella-zoster (VZV) gene 62 encodes a protein with a predicted Mr of 140,000 (140K) which has considerable amino acid identity with the major immediate early (IE) protein Vmw175 (ICP4) of herpes simplex virus type I (HSV-1). Vmw175 is an essential virus polypeptide with a pivotal role in the activation of early and late viral gene expression and also in the repression of IE gene expression. ...
