    ..alpha 1-Syntrophin appears to be associated mainly with dystrophin, as expected, but a small portion must be associated with another protein, possibly homologs of the electric tissue 87K protein. ..

    ..Our data indicate that Dp71f is a structural component of the beta1-integrin adhesion complex of PC12 cells that modulates PC12 cell adhesion by conferring proper complex assembly and/or maintenance. ..

    ..No apparent muscle degeneration was observed in heterozygous mutant mice, indicating that pathological changes caused by caveolin-3 gene disruption were inherited through the recessive form of genetic transmission. ..
