Actin (42 kDa) is the principal component of the cytoskeleton. It consists of globular monomers (G-actin) that polymerise to form helically symmetrical filaments (F-actin). A dynamic cytoskeleton is ...

This important study demonstrates that a peri-nuclear actomyosin network, present in some types of human cells, facilitates kinetochore-spindle attachment of chromosomes in unfavorable locations - ...
