Alternative splicing leads to different form of the same protein
The intron/exon-equivalent
structure of the human dystrophin gene
includes 35 exon-equivalents, of which 8 (those in green) are included or
excluded in various combinations to produce an mRNA that
is translated to make a tissue-specific form of the protein.
The very large number of combinations means that the protein
can be fine-tuned for tissue-specific functions.
