The absence of introns within a human fibroblast interferon gene.
Experiments in which immobilised restriction fragments of genomic DNA were hybridised with a cloned human fibroblast interferon cDNA indicate that the homologous chromosomal genes exist in only one basic arrangement. This is in marked contrast to recent studies by Nagata et al. (1) showing that there are at least eight gene arrangements for human leukocyte interferon. Having isolated a chromoso...
متن کاملNucleotide sequence of a rice genomic pyruvate decarboxylase gene that lacks introns: a pseudo-gene?
PDC (EC 4.1.1.1) is one of the anaerobic polypeptides that are induced under anaerobic stress (Rivoal et al., 1989; Peschke and Sachs, 1993). In plants these anaerobic inductions are believed to be associated with the plant’s need for increasing sugar carbon flow through the glycolytic pathway to generate energy in the absence of oxygen (Good and Muench, 1993). During anaerobiosis, the glycolyt...
متن کاملIntrons and gene evolution.
In one scenario of gene evolution, exon shuffling has a fundamental role in increasing gene diversity. As DNA sequences accumulate in the databases, the picture of the intron/exon structures of genes becomes more and more clear. We discuss in this review some features of this picture that suggest that introns have been present since the early stages of evolution, and that exon shuffling was a f...
متن کاملCLONING AND EXPRESSION OF A HUMAN INTERFERON a2 GENE IN E. COLI
The plasmid pALCA1SIFN containing cDNA that encodes the human interferon a-2b was obtained from the ATCC(no. 531667). In this system the expression of the gene is under the control of an alcA promoter. alcA p is a specific promoter for expression of different genes in Aspergillusfilamentous. In this plasmid the coding region of IFN?-2b is preceded by the coding region of a synthetic signal ...
متن کاملPharmacokinetic properties of human fibroblast and leukocyte interferon in rabbits.
When rabbits were given intramuscular injections of the same quantities of human leukocyte or fibroblast interferons, the former produced moderately higher levels of circulating interferon. Fibroblast interferon was not cleared faster from circulation, nor was direct inactivation by rabbit blood responsible for this difference.
