We have isolated the gene encoding the delta subunit of the mouse skeletal muscle acetylcholine receptor (AChR) and have identified a 148-bp cis-acting region that controls cell type-specific and differentiation-dependent gene expression. The 5' flanking region of the delta subunit gene was fused to the protein-coding region of the chloramphenicol acetyltransferase (CAT) gene and gene fusions w...
PURPOSE We previously demonstrated that 350 bp of the human rod cGMP phosphodiesterase beta-subunit (beta-PDE) gene promoter are sufficient to direct high levels of gene expression in human Y-79 retinoblastoma cells in vitro. In this study the cell specificity and expression pattern conferred by the short beta-PDE 5' flanking sequence in vivo were examined. METHODS A construct containing the ...
Cytochrome P450 oxidoreductase (POR) transfers electrons from NADPH to all microsomal cytochrome P450 (CYP) enzymes and is necessary for microsomal CYP activities. In this study, to find genetic variations and to elucidate the haplotype structures of POR, we comprehensively screened the genetic variations in the 5'-flanking region, all the exons and their flanking introns of POR for 235 Japanes...
When introduced as part of DNA constructions containing the human beta-globin locus control region (LCR), the human embryonic beta-globin gene, epsilon, is expressed in primitive but not definitive erythroid cells of recipient transgenic mice. In contrast to this pattern, the human fetal beta-globin gene, gamma, has been shown to be expressed in both primitive and definitive erythroid cells of ...
We have cloned a large portion of the P25 gene of Bombyx mori encoding the 25,000 dalton polypeptide which associates with fibroin to constitute the major silk protein. Its structure has been investigated by restriction mapping R-loop analysis, S1 nuclease protection experiments and nucleotide sequencing of the region spanning the 5' end of the gene and its flanking DNA. This has permitted a co...
