SB401 Bundles Microtubules
Potato pollen extract can phosphorylate microtubule-associated protein SB401 from Solanum berthaulti in vitro. The phosphorylated SB401 has no microtubule-bunding activity, suggesting that phosphorylation plays an important role in regulating SB401function. The cover picture shows how SB401 binds to and bundles microtubules. See pages 253–242 for details (cover design: Ying Wang).
