Cell biology: Spinning actin to divide
Shuh Narumiya1 & Issei Mabuchi2
Abstract
When our cells divide, they are cut down the middle by a tightening belt of proteins. New work reveals that the protein filaments in this belt are made from scratch every time.
The ability of cells to multiply lies at the heart of many biological processes. In multicellular organisms such as ourselves, cell proliferation is essential for growth and development, and to replace cells spent by daily wear and tear.
