Description |
Dystrophin is a rod-shaped cytoplasmic protein, and a vital part of a protein complex that connects the cytoskeleton of a muscle fiber to the surrounding extracellular matrix through the cell membrane. This complex is variously known as the costamere or the dystrophin-associated protein complex. Many muscle proteins, such as a-dystrobrevin, syncoilin, synemin, sarcoglycan, dystroglycan, and sarcospan, colocalize with dystrophin at the costamere. As of 2007, dystrophin is the longest gene known, covering 2.4 megabases (0.08% of the human genome) at locus Xp21. The primary transcript measures about 2, 400 kilobases and takes 16 hours to transcribe, the mature mRNA measures 14.0 kilobases. The 79 exons code for a protein of over 3500 amino acid residues. |
