A Japanese research group using microscopic video analysis provides deeper insight into the mechanics of plant cell division. Their analysis shows that actin filaments control the shape of cell ...

Since it was known that phosphate is released very rapidly from actin at the tip of the filament, called the barbed end, Raunser and his team determined its structure by cryo-EM.

Biochemists have determined how tiny synthetic molecules disrupt an important actin-related molecular machine in cells in one study and, in a second one, the crystal structure of that machine when ...

Actin filaments are one of the most abundant proteins in all mammalian cells. The filigree structures form an important part of the cytoskeleton and locomotor system.

A research team reveals a critical cellular mechanism that enables this navigation: the dynamic remodeling of actin filaments at the tip of pollen ...

Actin filaments have long been known to have polarity associated with their physical characteristics, but the mechanism behind how the filament is polarized has remained a mystery – until now.

Actin filaments are protein fibers that make up the internal skeleton of the cell. As active elements of our cells, actin filaments support the cell’s fusion, movement and are involved in many other ...

Actin filaments can be stabilized by distinct so-called "capping" proteins that bind to the filament ends to stop further addition or loss of individual actin proteins.

This is especially true for "thin filaments" - tiny filamentous structures made up of proteins called actin, troponin, and tropomyosin - owing to their complex interactions and small size.

University of Oregon biochemists have determined how tiny synthetic molecules disrupt an important actin-related molecular machine in cells in one study and, in a second one, the crystal structure ...
