| microfilament |
Actin is a globular protein that polymerize helicaly forming actin filaments (or microfilaments), which like the other two components of the cellular cytoskeleton form a three-dimensional network inside an eukariotic cell. Actin filaments provide mechanical support for the cell, determine the cell shape, enable cell movements (through pseudopods); and participate in certain cell junctions, in cytoplasmic streaming and in contraction of the cell during cytokinesis. ...
