Tantalizing clues in 4-billion-year-old asteroid Bennu samples could reveal particular molecular formations that some ...

Other recent work has identified a viral MP sequence that mimics a tubulin motif and allows the MP to bind to the microtubule lattice. Figure 1: View of microtubules at the edge of the ...

However, the molecular mechanism by which tubulin acetyltransferases modify microtubules and interact with paclitaxel remains unknown. There is an urgent need for research to clarify these ...

Microtubules are the largest type of filament, with a diameter of about 25 nanometers (nm), and they are composed of a protein called tubulin. Actin filaments are the smallest type, with a ...

Each day, a human adult loses on average 50 to 70 billion cells, which die from natural causes alone. New cells replace lost ...

Microtubules are composed of a protein called tubulin, which consists of alpha and beta subunits that assemble into large, tube-shaped filaments within the cell. These fibers are dynamic, growing from ...

Scientists reveal the role of hidden microbes called Asgard archaea in the origins of complex life, challenging long-held views of evolution.

Microtubules are dynamic structural polymers composed of protein building blocks called tubulin that add and lose fragments at their ends. Supercomputer simulations by University of Chicago and ...

GAS2 is a cytoskeletal regulator that interacts with both F-actin and microtubules. Here, cryo-EM structures of GAS2 domains ...

During mitosis, tubulin proteins link together to form long microtubules. The microtubules reach from the edges of the cell towards the center to grab and pull sister chromatids to opposite sides of ...
