The human fibroblast adenine nucleotide translocator gene. Molecular cloning and sequence.

The human adenine nucleotide translocator multigene family consists of three transcribed genes and at least seven pseudogenes. We report the cloning and sequencing of the gene expressed in human fibroblasts. Like the other two transcribed genes, it has four exons. The 5'-flanking region of the fibroblast translocase gene contains a functional promoter. The promoter has a TATA motif beginning 30 base pairs upstream of the transcription initiation site and five potential SP1 binding sites, but lacks a canonical CCAAT box immediately upstream of the TATA sequence. Differences among the sequence motifs of the 5'-flanking region of the three human translocase genes could account for differences in their cell type-specific and proliferation-associated expression.
