The promoter of the gene for the human precursor of Alzheimer's disease A4 amyloid protein (PAD gene) resembles promoters of housekeeping genes. It lacks a typical TATA box and shows a high GC content of 72% in a DNA region that confers promoter activity to a reporter gene in an in vivo assay. Transcription initiates at multiple sites. Sequences homologous to the consensus binding sites of transcription factor AP-1 and the heat shock control element binding protein were found upstream of the RNA start sites. Six copies of a 9-bp-long GC-rich element are located between positions -200 and -100. A protein--DNA interaction could be mapped to this element. The 3.8 kb of the 5' region of the PAD ..
