Movie 1

In vitro reconstitution of contractile actin rings.
This movie shows the contraction of networks of actin filaments (red) assembled on a 60-micron-wide 18-dot micropattern of pWA upon the addition of double headed GFP-myosin-VI (green). The white circle and the white cross mark the initial shape of the ring and its centre. Actinin was added only on the right movie at a final concentration of 20 nM.
