What is F-Actin (Filamentous Actin)?
F-Actin refers to the polymerized form of actin protein. It forms long chains or filaments, providing structural support to the cell and facilitating various cellular processes such as cell shape maintenance and cell movement.
F-Actin Structure
The F-Actin structure forms a helical structure with two strands of G-Actin monomers twisted around each other. This filamentous structure provides stability and rigidity to the cytoskeleton.
F-Actin Function
F-Actin filaments are involved in various cellular processes including cell migration, muscle contraction, cytokinesis, and maintenance of cell shape. They serve as tracks for motor proteins and participate in the formation of cellular protrusions such as filopodia and lamellipodia.
F-Actin Dynamics
F-Actin filaments are highly dynamic and can undergo constant assembly and disassembly through the addition or removal of G-Actin subunits at their ends.
Difference Between G-Actin and F-Actin
The difference between G-Actin and F-Actin lies in their structure and function. G-actin (globular actin) is a monomeric protein that polymerizes to form F-actin (filamentous actin), which is a long chain of actin monomers crucial for cell structure and movement. G-actin and F-actin are two forms of actin, a protein that plays critical roles in various cellular processes.
We will cover the difference between G-actin and F-actin in this article.
