Visualizing “Unfurling” Microtubule Growth

Microtubule fibers are hollow rods made of much smaller tubulin subunits that spontaneously assemble at one end of the rod, but exactly how they do this inside the crowded environment of living cells has been a mystery. UC Davis researchers have uncovered the mechanism that puts these blocks in place, illustrated in a new animation.

Understanding Traffic Congestion on the Shifting Roadways of Cell Division

In a new study appearing in Developmental Cell, Ruensern Tan, a biochemistry, molecular, cellular and developmental biology graduate student, and Assistant Professor Richard McKenney, Department of Molecular and Cellular Biology, provide a new molecular model to describe the role of motor proteins in restructuring the cytoskeleton for cell division.
