Localization of CAP in striated muscle. (A) Mouse neonatal cardiomyocytes were costained with α-actinin and CAP. CAP localizes to focal adhesions (arrows) and costameres (arrowheads). (B) Mouse heart sections were stained with CAP and α-actinin or vinculin. CAP localizes to intercalated discs (arrows) and costameres (arrowheads). (C) Cross or longitudinal sections of mouse soleus muscle were stained with CAP and α-actinin or caveolin 3. CAP localizes to the sarcolemma membranes, with concentrated regions on the cross sections (arrows). Staining of the longitudinal sections showed CAP localization at costameres and MTJs (arrowheads).
