Dynamics of Fos-Jun-NFAT1 complexes.
Transcription initiation in eukaryotes is controlled by nucleoprotein complexes formed through cooperative interactions among multiple transcription regulatory proteins. These complexes may be assembled via stochastic collisions or defined pathways. We investigated the dynamics of Fos-Jun-NFAT1 complexes by using a multicolor fluorescence resonance energy transfer assay. Fos-Jun heterodimers ca...
متن کاملIntracellular Glutathione Levels Regulate Fos/Jun Induction
Induction of glutathione S-transferase Ya and NAD(P)H:quinone reductase gene expression by a variety of chemical agents is mediated by regulatory elements, EpRE and ARE, composed of two adjacent AP-l-like binding sites and activated by Fos/Jun heterodimeric complex (AP-1). Recent studies show that chemical induction of glutathione S transferase Ya and quinone reductase gene expression is associ...
متن کاملDifferential roles for Fos and Jun in DNA-binding: redox-dependent and independent functions.
The Fos and Jun family of transcription factors contain an invariant sequence motif lysine-cysteine-arginine (KCR) in the highly conserved DNA-binding region. Reduction of the cysteine residue is necessary to facilitate DNA-binding. Here, we examined the potential dual roles of the flanking lysine and arginine residues in influencing the redox reactivity of the cysteine and the DNA-binding acti...
متن کاملDimerization and DNA binding alter phosphorylation of Fos and Jun.
Fos and Jun form dimeric complexes that bind to activator protein 1 (AP-1) DNA sequences and regulate gene expression. The levels of expression and activities of these proteins are regulated by a variety of extracellular stimuli. They are thought to function in nuclear signal transduction processes in many different cell types. The role of Fos and Jun in gene transcription is complex and may be...
متن کاملEnergy transfer analysis of Fos-Jun dimerization and DNA binding.
The protooncogenes fos and jun encode proteins that bind to DNA as dimeric complexes and regulate gene expression. Protein dimerization is mediated by a leucine zipper and results in juxtaposition of regions of each protein rich in basic amino acids that comprise a bimolecular DNA binding domain. We have developed an approach based on resonance energy transfer for the quantitative analysis of d...
