From NeuroLex
| Name: | Microfilament (sao2006047981) |
| Definition: | A two-stranded helical polymer of the protein actin. Actin filaments are a major component of the contractile apparatus of skeletal muscle and the microfilaments of the cytoskeleton of eukaryotic cells. The filaments, comprising polymerized globular actin molecules, appear as flexible structures with a diameter of 5-9 nm. They are organized into a variety of linear bundles, two-dimensional networks, and three dimensional gels. In the cytoskeleton they are most highly concentrated in the cortex of the cell just beneath the plasma membrane. Reference(s): ISBN 0198506732 PMID 10666339 (GO) |
