A Northwestern Medicine study has shed light on one of the most intricate construction projects in biology: how cells build ...

A new study by researchers from Drexel University College of Medicine reverses the popular scientific dogma that the protein tau stabilizes microtubules within brain cells. The scientists’ new ...

For the first time, researchers have directly visualized how newly formed cellular organelles leave the endoplasmic reticulum ...

Microtubules are cell constituents that display several astounding properties and a unique pattern of behavior during the cell cycle. Microtubules are regulated by several proteins and complexes, and ...

Representative kymographs showing single GFP-tagged ATAT-2 molecules on GMPCPP-stabilized MEC-12/MEC-7 (left) and TBA-2/TBB-2 (right ...

As organisms grow, live, and move through the world, they're subjected to an array of internal and external forces. Biological forms must be able to withstand the stresses of stretching and ...

Almost all cell types exhibit some form of polarity; cell polarity refers to the spatial differences in shape, structure and function within a cell, which enables the cell to carry out specialized ...

Microtubules help to regulate cell structure throughout our bodies. A group of researchers have used cryo-electron microscopy to shed light on how a certain protein keeps microtubules stable, and ...

Filamentous polymers called microtubules play vital roles in chromosome segregation and molecular transport. An team has now examined how microtubule lengths vary in response to changes in the ...
