SECOND CALPONIN HOMOLOGY DOMAIN FROM UTROPHIN
OverviewOverview
Utrophin is a close homologue of dystrophin, the protein defective in, Duchenne muscular dystrophy. Like dystrophin, it is composed of three, regions: an N-terminal region that binds actin filaments, a large central, region with triple coiled-coil repeats, and a C-terminal region that, interacts with components in the dystroglycan protein complex at the, plasma membrane. The N-terminal actin-binding region consists of two, calponin homology domains and is related to the actin-binding domains of a, superfamily of proteins including alpha-actinin, spectrin and fimbrin., Here, we present the 2.0 A structure of the second calponin homology, domain of utrophin solved by X-ray crystallography, and compare it to the, other calponin homology domains previously determined from spectrin and, fimbrin.
