    Abstract:
    We report four variants and alternative promoter usage for the mouse acyl-CoA synthetase 6 (mAcsl6) gene. The variants, which were organized into 26 exons and 25 introns spanning 55 kb of DNA on mouse chromosome 11, were classified according to their 5'-UTRs and alternative splicing of exon 13. Alignment of the nucleotide sequences showed that the mAcsl6 variant 1 (mAcsl6_v1) and mAcsl6_v2 used a different promoter and had different splicing patterns than mAcsl6_v3 and mAcsl6_v4. The results of the promoter analysis suggest that the mAcsl6 promoter 1 (mAcsl6_pr1) region has a negative regulatory function. To verify this result, we constructed id vector constructs that contained the promoter regions mAcsl6_pr1 and 2, and the chimeric transcript. Although the mAcsl6_pr1 region was deleted, the mAcsl6_v1 and 2 transcripts were detected consistently.
