The 5' upstream regulatory region of the gene encoding the rat amyloid precursor protein (APP) was cloned and sequenced. It lacks both a TATA box and a CAAT box, has a high G + C content (68%), is 89% homologous to the corresponding region of the mouse APP gene, and 82% homologous to the corresponding region of the human APP gene. This region contains putative regulatory elements both 5' and 3' to the probable transcription start point (tsp). There are consensus DNA sites for the binding of SP1, AP2, AP4 and GC factor (GCF) proteins, and two GC boxes with the consensus sequence, 5'-GGGYGCRG. Potential regulatory sites with only a single mismatch to the consensus sequences include three SP1, one AP1, five AP2, and two GCF sites, as well as one GC box. There are also six potential stem-loop secondary structures (SSS) near the probable tsp. A consecutive series of elements, consisting of a GC box, AP2 site, three SSS, two SP1 sites, and AP4, AP1 and GCF sites just upstream from the probable tsp, are well-conserved between the rat, mouse and human sequences. An additional AP2 site, two GC boxes, and two additional SSS appear to be conserved between species. However, two possible rat SP1 sites, three possible rat AP2 sites, and two possible rat GCF sites are lacking in the human. On the other hand, the rat sequence is missing four potential SP1 sites, four potential AP2 sites, and nine potential GC boxes which are found in the human sequence.(ABSTRACT TRUNCATED AT 250 WORDS)

D003001	Cloning, Molecular	The insertion of recombinant DNA molecules from prokaryotic and/or eukaryotic sources into a replicating vehicle, such as a plasmid or virus vector, and the introduction of the resultant hybrid molecules into recipient cells without altering the viability of those cells.	Molecular Cloning
D004247	DNA	A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).
