Absence of dystrophin results in Duchenne muscular dystrophy (DMD), a lethal neuromuscular d isorder that afflicts 1 in 3500 live male births. In the sarcolemma, dystrophin is associated with a complex of proteins and glycoproteins, known as the dystrophin glycoprotein complex. The DGC constituents are dystrophin, a-dys troglycan, b-dystroglycan, syntrophin, a-sarcoglycan, b-sarcoglycan, g-sarcoglycan, d-sarcoglycan, and sarcospan. Not al l of these are single protein species. The syntrophins consists of a group of three homologous proteins composed of acidic (a) and basic (b) components. Syntrophins are known to self-associate to form oligomers.
In this dissertation, syntrophin's oligomerization and its interactions with …
