Characterization of the transcription-initiation site and of the promoter region within the 5' flanking region of the human aldolase C gene.
Several aldolase C clones from a human genomic library have been identified using a mouse aldolase C cDNA as a hybridization probe. The most complete fragment of the clones identified is 14 kb long and contains the complete aldolase C gene. The nucleotide sequence analysis of more than 5 kb includes the intron/exon organization structure of the gene and the 3' and 5' flanking regions. Although no human cDNA is yet available, a canonical polyadenylation signal at the 3' end of the gene indicates the proximity of the poly(A) addition site. We have analyzed the 5' noncoding region by S1 mapping and primer-extension experiments. The transcription-initiation sites for the human aldolase C gene in brain tissue was located about 1300 bp upstream from the methionine initiation codon. Preliminary functional assays of the promoter by transfection into rat glioma cells have indicated that promoter elements lie between positions -161 and -416 from the start point of transcription.
