Characterization of the 5'-flanking region of the gene encoding bovine adenylate kinase isozyme 3.
We have characterized the 5'-flanking region of the gene encoding bovine adenylate kinase isozyme 3 (AK3). S1 mapping analysis revealed multiple transcription start points in the bovine AK3 gene. The promoter activities were tested in HeLa cells using the chloramphenicol acetyltransferase (CAT) gene as a reporter. The CAT analysis showed that the basal promoter sequence was located within the region from -189 to +228. In the presence of short DNA fragments of the 5'-flanking region as competitors, the transcriptional activity of the bovine AK3 promoter changed depending on the fragments used. The results identified the basal regulatory elements in the proximal promoter region.
