Researchers at UT San Antonio have uncovered new details about electrical signals happening within nerve cells, deepening ...

Like poles support a tent, microtubules—hollow cylindrical structures made of tubulin protein—support eukaryotic cells. But microtubules provide more than just mechanical strength; they help prepare ...

The generation and survival of all organisms requires the precise partitioning of duplicated chromosomes to daughter cells. Defects in segregation lead to aneuploidy, the state in which entire ...

Atomic force microscopy (AFM) represents a better choice compared to light-based microscopy methods for the stufy of microtubules. For instance, the AFM can be used in buffers to image samples at a ...

The tubulin family of proteins are vital components of the eukaryotic cytoskeleton and are the main constituent of microtubules in living cells. The tubulin proteins α- and β polymerize into long ...

B(αβ) tubulin was obtained from a homogeneous class of microtubules, the incomplete B subfiber of sea urchin sperm flagellar doublet microtubules, by thermal fractionation. The thermally derived ...

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 ...

A pathway to the design of even more effective versions of the powerful anti-cancer drug Taxol has been opened with the most detailed look ever at the assembly and disassembly of microtubules, tiny ...

(Nanowerk News) Microtubules, hollow fibers of tubulin protein only a few nanometers in diameter, form the cytoskeletons of living cells and play a crucial role in cell division (mitosis) through ...

Methods were developed for the isolation of Chlamydomonas flagella and for their fractionation into membrane, mastigoneme, "matrix," and axoneme components. Each component was studied by electron ...
