Fig. 9. IF-enriched cytoskeletons contain motor subunits. Lane `IF' is a Coomassie stain showing that peripherin (P) is the major protein present in IF-enriched cytoskeletal preparations. Immunoblot analysis of these same preparations shows that kinesin and many of the components of dynein and dynactin are present. MW indicates molecular weight standards. DIC, dynein intermediate chain; DLIC1 /2, dynein light intermediate chain isoforms 1 and 2; DHC, dynein heavy chain; p50, dynamitin; Arp-1, actin related protein-1; KHC, kinesin heavy chain.
