title: Cloning and structural characterization of a rabbit genomic DNA for alpha 1 acid glycoprotein.
abstract: The gene for rabbit alpha 1 acid glycoprotein (AGP) has been isolated from a lambda EMBL3 genomic DNA library. Isolated clone contains a 12 Kbp fragment of rabbit genomic DNA. Restriction endonuclease mapping has localized the gene within a 4.2 Kbp fragment spanning two EcoRI sites. Southern blot analysis of the rabbit genomic DNA and its comparison with the cloned gene indicates that there is only one gene for AGP present per genome. DNA sequence analysis of the cloned gene indicates that the entire gene, TATA box to the polyadenylation signal, is located within the 4.2 Kbp region and contains six exons representing the full-length cDNA described earlier (1). The 5'-end of alpha 1-AGP gene sequences from rabbit, human, rat and mouse have been compared. Such analysis reveals two conserved regions located between -63 bp and -36 bp and -29 bp and -1 bp of putative transcription start site, which may play a role in transcriptional induction of this gene during acute response. In addition to this conserved domain, DNA sequence upstream of the major transcription start site contains a potential element for Sp1 binding and a 18 bp long palindrome sequence followed by a short repeating dinucleotide sequence, which may be important in the regulation of AGP gene induction.
