Researchers at Kanazawa University report in eLife on deciphering the actin structure-dependent preferential cooperative binding of cofilin. The actin filament is a double-stranded helical structure ...

Formins are highly dynamic proteins that assemble filaments rapidly, hence it is difficult to obtain enough filament ends for detailed structure determination. The MPI scientists analyzed not just one ...

Model showing the release of phosphate in different parts of the actin filament. Actin in the core of the filament has a closed door while the back door at the end of the filament is open. A mutation ...

“We are answering fundamental questions of life that scientists have been trying to answer for several decades”, remarks Raunser. In eukaryotic cells, actin proteins are abundant and tend to join ...

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 assembly and disassembly.

Actin filaments - protein structures critical to living movement from single cells to animals - have long been known to have polarity associated with their physical characteristics, with growing ...

Research has demonstrated that actin waves propagate via actin polymerization on the substrate-attached cell membrane at the wave’s front and disassembly at the back of the wave. 4 Proteins named Arp2 ...

Actin proteins assemble into thin, helical filaments that form a network throughout all eukaryotic cells. These filaments play a significant role in cell structure, movement, division, and more. This ...

Cells in the human body are made to move. They assemble during embryo development, migrate to repair tissue, hunt pathogens, and perform a host of other tasks requiring travel. As part of the ...
