Living cells are highly organized, yet they are not assembled using rigid blueprints or by following a predetermined plan.

The dynamic processes that occur during the growth of actin, via polymerization, and the breakdown of actin both play significant roles in cellular mechanisms like migration and adhesion. Due to the ...

Scientists have uncovered a surprising new way that giant embryonic cells divide—without relying on the classic “purse-string” ring long thought essential for splitting a cell in two. Studying ...

A buildup of a structural protein called F-actin inside aging brain cells appears to cripple the cellular waste-clearing machinery that keeps neurons healthy, according to a study in Drosophila fruit ...

Depositphotos A closer examination revealed that the F-actin had messed up the cell’s recycling system. The researchers found that preventing F-actin accumulation, caused more autophagy in the brains ...

Researchers have visualized at the molecular level how formins bind to the ends of actin filaments. This allowed them to uncover how formins mediate the addition of new actin molecules to a growing ...

What am I looking at? This video shows actin at work in a growing intestinal organoid. The video is depth-coded for color, which means that cooler colors like blue and purple are closer to the viewer ...
