Cytoskeleton components, artwork
Cytoskeleton components, artwork. Three main components of the cytoskeleton, the internal support structure of a cell, are shown here. At top, the globular protein actin (orange) forms a microfilament, the thinnest of the filaments found in the cytoskeleton. At centre, intermediate filaments (red) are composed of a family of various proteins. The thickest of the filaments are the microtubules (green) at bottom, composed of the protein tubulin. The respective diameters in nanometres are actin filament (6), intermediate filament (10), microtubule (25). For their roles in a cell, see image C009/7406

EDITORS COMMENTS
This artwork showcases the intricate components of the cytoskeleton, the internal support system of a cell. The print highlights three main elements that contribute to the structural integrity and functionality of cells. At the top, we see an orange microfilament made up of actin, a globular protein. This thin filament is responsible for various cellular processes such as cell movement and shape maintenance. In the center, red intermediate filaments are depicted, composed of a diverse family of proteins. These medium-sized filaments provide mechanical strength to cells and help anchor organelles in place. At the bottom, green microtubules steal our attention with their thickness compared to other cytoskeletal elements. Composed primarily of tubulin proteins, these large filaments serve as tracks for intracellular transport and play crucial roles during cell division. The diameters provided in nanometers offer perspective on their relative sizes: actin filament (6 nm), intermediate filament (10 nm), and microtubule (25 nm). This stunning illustration not only captures the beauty within cellular structures but also emphasizes their importance in maintaining proper cell function. It serves as a reminder that even at microscopic levels, art can be found in science's exploration into life's building blocks.
