Characterization of the mouse metal-regulatory-element-binding proteins, metal element protein-1 and metal regulatory transcription factor-1.
Metal activation of metallothionein gene transcription depends mainly on the presence of regulatory DNA sequences termed metal-regulatory elements (MREs) and involves MRE-binding transcription factor-1 (MTF-1) interacting with the MREs in a Zn(2+)-dependent manner. We previously identified and characterized a nuclear protein, termed metal element protein-1 (MEP-1), specifically binding with hig...
متن کاملTranscriptional Regulation of the Beta-Synuclein 59-Promoter Metal Response Element by Metal Transcription Factor-1
The progression of many human neurodegenerative disorders is associated with an accumulation of alpha-synuclein. Alphasynuclein belongs to the homologous synuclein family, which includes beta-synuclein. It has been proposed that betasynuclein may be a natural regulator of alpha-synuclein. Therefore controlling beta-synuclein expression may control the accumulation of alpha-synuclein and ultimat...

متن کاملActivation of metallothionein gene expression by hypoxia involves metal response elements and metal transcription factor-1.
Metallothioneins (MTs) are a family of stress-induced proteins with diverse physiological functions, including protection against metal toxicity and oxidants. They may also contribute to the regulation of cellular proliferation, apoptosis, and malignant progression. We reported previously that the human (h)MT-IIA isoform is induced in carcinoma cells (A431, SiHa, and HT29) exposed to low oxygen...
متن کاملBalance between metallothionein and metal response element binding transcription factor 1 is mediated by zinc ions (review).
Metal ion homeostasis and heavy metal detoxification systems are regulated by certain genes associated with metal ion transport. Metallothionein (MT) and metal response element binding transcription factor 1 (MTF‑1) are important regulatory proteins involved in the mediation of intracellular metal ion balance. Differences in the zinc‑binding affinities of the zinc fingers of MTF‑1 and the α‑ an...
