Molecular cloning and expression of the mouse ornithine decarboxylase gene.
We used mRNA from a mutant S49 mouse lymphoma cell line that produces ornithine decarboxylase (OrnDCase) as its major protein product to synthesize and clone cDNA. Plasmids containing OrnDCase cDNA were identified by hybrid selection of OrnDCase mRNA and in vitro translation. The two of these with the largest inserts together span 2.05 kilobases of cDNA. Southern blot analysis of DNA from wild-...
متن کاملIsolation and expression of a human ornithine decarboxylase gene.
We have isolated a human ornithine decarboxylase (ODC) gene from a leukocyte genomic DNA library in order to examine the mechanisms involved in the regulation of ODC gene expression in normal and neoplastic cell growth. Nucleotide sequence analysis shows that the human ODC gene in clone ODC709-A2 consists of 12 exons which encode a protein identical to that inferred from a human ODC cDNA sequen...
متن کاملMouse ornithine decarboxylase gene: cloning, structure, and expression.
We used molecular cloning to isolate a functional gene for mouse ornithine decarboxylase (OrnDCase; L-ornithine carboxy-lyase, EC 4.1.1.17) from a cell line in which that gene had been selectively amplified. The position of the 5' terminus of the mRNA was identified, and the coding sequence was shown to be preceded by a 312- or 313-nucleotide (nt) untranslated leader. The latter is highly G + C...
متن کاملCharacterization of a transgenic mouse line over-expressing the human ornithine decarboxylase gene.
We have produced several transgenic mouse lines over-expressing the human ornithine decarboxylase (ODC) gene. We have now characterized one of the transgenic lines as regards the tissue accumulation of the polyamines and the activities of their metabolizing enzymes. Among the tissues analysed, the polyamine pattern was most strikingly changed in testis and brain of the transgenic animals. ODC a...
متن کاملMouse ornithine decarboxylase-like gene encodes an antizyme inhibitor devoid of ornithine and arginine decarboxylating activity.
Ornithine decarboxylase (ODC), a key enzyme in the biosynthesis of polyamines, is a labile protein that is regulated by interacting with antizymes (AZs), a family of polyamine-induced proteins. Recently, a novel human gene highly homologous to ODC, termed ODC-like or ODC-paralogue (ODCp), was cloned, but the studies aimed to determine its function rendered contradictory results. We have cloned ...
