ABSTRACT
Human apolipoprotein A-I (ApoA-I) is a major structural and functional protein component of high-density lipoprotein (HDL). ApoA-I constitutes ~75% of the protein content of HDL. The main sites of ApoA-I synthesis in humans are the liver and the small intestine. The mechanisms that govern tissue-specific apoA-I transcription in tissues and organs other than the liver and the small intestine are poorly understood. It is known that the human apoA-I has two additional promoters, the proximal and the distal one. In this work these two alternative apoA-I promoters are characterized, their transcription start sites are mapped and their competition for apoA-Itranscription is demonstrated; the role of the alternative promoters in apoA-I expression in human cells and tissues other than hepatocytes and enterocytes is discussed.
