What are the Cellular Processes of Actin?
Some cellular processes that use actin filaments are as follows:
Process |
Description |
---|---|
Cell Migration |
Directed movement of cells |
Movement in muscle cells by contraction and relaxation |
|
Engulfing materials into cells via actin-mediated processes (phagocytosis, pinocytosis) |
|
Cytokinesis |
Involved in cell division |
It is major component of the cytoskeleton of the cell. Maintains cell shape and provide structural support. |
|
Cell adhesion |
They are involved with attachment of cells to structures, such as focal adhesions. |
Intracellular transport |
They are involved in intracellular transport mechanisms, facilitating vesicle mobility. |
Cellular protrusions |
They generate cellular protrusions called filopodia, which help in cell communication |
Actin Filaments
Actin filaments are microscopic, filamentous structures present in the cytoskeleton. Actin filaments function in cell movement, providing structural support, and facilitating cellular processes such as cytokinesis and cell division. These filaments are dynamic polymers made up of actin protein subunits that create complex networks within cells. In this article, we will look at the structure, function, and dynamics of actin filaments and how they affect cellular functions.
