The nucleotide sequence of the human alpha-albumin gene, including 887 bp of the 5'-flanking region and 1311 bp of the 3-flanking region (24,454 in total), was determined from three overlapping lambda phage clones. The sequence spans 22,256 bp from the cap site to the polyadenylylation site, revealing a gene structure of 15 exons separated by 14 introns. The methionine initiation codon ATG is w...

Insulin-like growth factor 1 (IGF1) is a mediator of the effects hormone and polymorphism in IGF1 gene reported to affect fat deposition some livestock species. In this study, nucleotide sequence variation three regions ovine (part 5' flanking region, exon 3 4 region) was investigated 848 New Zealand Romney lambs using PCR-single strand conformation (SSCP) analyses ascertain if single polymorph...

The gene encoding the mouse vitamin D receptor has been cloned. A new exon 1 has been found that changes the numbering established for the human VDR gene. Exons 2 and 3 in the human VDR gene (coding for the zinc fingers 1 and 2, respectively) are named exons 3 and 4 in the mouse vitamin D receptor. The 1.5-kb 5'-flanking region of the new exon 1 was analyzed and revealed the presence of putativ...

The Class 3 aldehyde dehydrogenase gene (ALDH-3) is differentially expressed. Expression is either constitutive or xenobiotic inducible via an aromatic hydrocarbon (Ah) receptor-mediated pathway, depending upon the tissue. A series of studies were performed to examine the regulation of rat ALDH-3 basal expression. DNase I footprint analysis identified four DNA regions within the proximal 1 kb o...

A genomic clone, encompassing the 5' flanking region and the first seven exons of rat ATP citrate lyase gene, was isolated from a rat genomic library and sequenced. Primer-extension analysis showed that mRNA is transcribed at 4407 nucleotides upstream from the translation start site. Primer-extension analysis and sequencing of ATP citrate lyase cDNA amplified by PCR showed that the promoter use...

PURPOSE This study focuses on the identification of regulatory elements that contribute to lens-specific expression of the human CP49 gene within the 5'-flanking DNA sequences. METHODS The DNA sequence upstream of the human CP49 coding region was subcloned as a set of 5' and 3' deletion series. The constructs were transfected into lens (N/N1003A) and nonlens (NIH3T3) cell lines and chicken pr...

Erythropoietin gene expression is greatly stimulated under conditions of hypoxia. The activation of the erythropoietin gene appears regulated primarily at the level of gene transcription. To study cis-acting elements involved in the response to hypoxia a mini-gene was constructed by an internal deletion from exon II to V of the human erythropoietin gene and used in transient transfection assays...
