Spc72p does not bind microtubules in vitro. 35S-labeled in vitro–translated Stu2p and Spc72p were incubated without microtubules (−) and with 5 μM taxol-stabilized bovine brain microtubules (+). Microtubules were then pelleted by centrifugation, and pellet (P) and supernatant (S) fractions were subjected to SDS-PAGE analysis. Bands were visualized and quantitated using a phosphoimager.
