In all eukaryotic cells, actin protein assembles to form a network of thin filaments that spread throughout the cell. The actin filaments give the cell its structure, enable the cell to move, and ...

Actin proteins group together to form a network of thin filaments that spread throughout a cell. This actin network is dynamic, meaning that the filaments can either grow or shrink to fit the ...

Filopodia help cells move but also aid cancer spread. Scientists have revealed how fascin proteins build these structures, ...

Alushin's lab specializes in understanding the cytoskeleton—the network of protein filaments, including actin, that form a cell's infrastructure. Actin serves many functions: it provides cells with an ...

This DD-AcGPF1-actin fusion was only stable in the presence of Shield1 (Fig. 3). The ProteoTuner system makes it possible to change the amount of a protein of interest rapidly, so it is possible ...

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 ...

Sep. 28, 2023 — Actin filaments are dynamic protein-fibers in the cell built from single actin proteins. Many cellular functions, including cell movement, are regulated by constant filament ...

The forces at work Alushin’s lab specializes in understanding the cytoskeleton—the network of protein filaments, including actin, that form a cell’s infrastructure. Actin serves many ...

Researchers had also described the bacteria quickly spreading among neighboring cells. But Portnoy, who joined UPenn’s medical school in 1988, had found he could block this cell-to-cell spread by ...
