Alternative Promoters for the Human Dystrophin gene
The human dystrophin
gene extends almost 2.5 million bases, and
includes a large number of exons separated by
larger intron regions. Depending on the tissue
type and developmental stage, any of seven different promoters
(start signals) may be used to transcribe all or a
part of the gene region and produce variants of the gene
product.
