Atomic resolution of muscle contraction

At the molecular level, muscle contraction is defined by myosin molecules pulling actin filaments. New electron cryomicroscopy images with unprecedented resolution taken by researchers at Osaka University reveal unexpectedly ...

Proteins found to spontaneously form whorls and lattices

(PhysOrg.com) -- Building on the work of a previous team that found filaments made from actin, when combined with so called motor proteins, moved themselves into distinct patterns, a new team in Japan has found that combining ...

Actin cytonauts at play in the cell

(Phys.org) —Actin "comets" are scaffolds of polymer that various bacteria and viruses construct within cells. Party-crashers, like Listeria or Shigella bacteria, are able to seed structures using special patches of their ...

Video captures cellular 'workhorses' in action

Scientists at Yale University and in Grenoble France have succeeded in creating a movie showing the breakup of actin filaments, the thread-like structures inside cells that are crucial to their movement, maintenance and division.
