Upstream open-reading frames are unusual in mammalian mRNAs. The 5' untranslated region of ADH5 mRNA contains an upstream open-reading frame (uORF) with two possible AUG start codons. Myf6 mRNA contains three tandem AUG repeats at the translation start site, a rare feature. Mutation at one or both of the upstream AUG codons in the ADH5 mRNA increased gene(More)
We investigated transacting factors binding to the cis-element important in tissue-specific expression of the human glucose transporter type 2 isoform (GLUT2) gene. By transient transfection assay, we determined that the 227-base pair fragment upstream of the ATG start site contained promoter activity and that the region from +87 to +132 (site C) was(More)
Human chi-alcohol dehydrogenase (chi-ADH) is a zinc-containing dimeric enzyme responsible for the oxidation of long-chain alcohols and omega-hydroxyfatty acids. Class-III ADHs, of which chi-ADH is the prototype, are widely produced and well conserved during evolution. This suggests that they fulfill important housekeeping roles in cellular metabolism.(More)
Suppressors of cytokine signaling (SOCS) are negative regulators of cytokine-induced signal transduction, which play multiple roles in cell growth, differentiation and apoptosis. In this study, the regulatory role of SOCS in oxidative stress-induced apoptosis was investigated. In Jurkat T cells and mouse splenocytes, we have found that SOCS1 is induced in(More)
The human alcohol dehydrogenase 5 gene (also known as the formaldehyde dehydrogenase gene, ADH5/FDH) has a GC-rich promoter with many sites at which transcription factors bind. A minimal promoter extending from -34 base pairs (bp) to +61 bp directs high levels of transcription in several different cells, consistent with the ubiquitous expression of the(More)
We have cloned and sequenced a cDNA encoding the mouse class III alcohol dehydrogenase, Adh-B2. Adh-B2 mRNA is detectable in all the mouse tissues tested. Class III ADHs are highly conserved: the deduced amino acid sequence of the mouse Adh-B2 is 91 to 97% identical to the human, horse and rat liver enzymes. The mouse Adh-B2 cDNA is 87% identical in(More)
