    ..Our results suggest that the 59-DAP triplet may contain different protein species and that the 59-1 DAP may associate more specifically with dystrophin than with utrophin. ..

    ..a relative from human skeletal muscle, EST25263, which is probably a human homologue of the published mouse syntrophin 2. We have mapped the human basic component of A1 and EST25263 genes to chromosomes 8q23-24 and 16, respectively.

    ..Since individual syntrophins do not have intrinsic binding specificity for dystrophin, dystrobrevin, or utrophin, the observed preferential pairing of syntrophins must depend on extrinsic regulatory mechanisms. ..

    ..Collectively, our data suggest that syntrophins link NaChs to the actin cytoskeleton and the extracellular matrix via dystrophin and the DAPC. ..

    ..Our findings demonstrate that syntrophin and utrophin associate with alpha(1D)-ARs to create a functional signalosome, which is essential for alpha(1D)-AR regulation of vascular tone and blood pressure. ..
