    ..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. ..

    ..We demonstrated a direct protein interaction between MLC1 and Kir4.1. From these results we conclude that MLC1 is associated with the DGC at astrocytic endfeet...

    ..Because pathological mutations prevent MLC1 membrane expression, the identification of substances regulating MLC1 intracellular trafficking is potentially relevant for the therapy of MLC. ..

    ..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. ..
