Myosin II plays the most important role in cellular force generation. Myosin II molecules self-assemble into filaments with different structures depending on myosin II isoforms and other conditions ...

Cell migration involves complex protein signaling cascades and changes in the structure of the cell's actinomyosin cytoskeleton ... synthetic or derived from animal products, allowing researchers ...

The long tail of a sperm cell, the finger-like cilia in the lungs, and the long axons of nerves are all built with microtubules—basic building blocks of the cell’s cytoskeleton ... proteins confer ...

Before arriving at Janelia three years ago, Postdoctoral Scientist Antonio Fiore was designing and building optical ...

Rhobo6, a light microscopy probe, gives scientists an unprecedented look at the extracellular matrix -- the collection of organized molecular structures that fills the spaces between cells in our ...

This influx of calcium at the contact site attracts and activates a kinase called CaMKII, a protein known to be important in ...

A complex molecular machine, the spliceosome, ensures that the genetic information from the genome, after being transcribed into mRNA precursors, is correctly assembled into mature mRNA. Splicing is a ...

The new research reveals a novel mechanism for signal transmission in brain cells and helps answer an open question in neuroscience about how intracellular signals travel over long distances in ...

The diagram below shows the same plant cell, as viewed with the light microscope, and with the transmission electron microscope. Animal and plant cells have certain structures in common.

Many cells in multicellular organisms are specialised. They have specific roles in the organism of which they are part. Their structure is adapted to their function. They are often grouped ...

These forces range from mechanical stress signal generation, induction, and transduction to the final response, which involves the cell membrane, cytoderm, cytoskeleton, and other structures. The ...
