General description

Actin is an abundantly expressed in eukaryotic cells and it is the core component of the cytoskeleton. It exists in three isoforms: alpha actin, which is found in muscle tissue and forms fibrous actin that facilitates muscle contractility; and beta and gamma actin which are found in non-muscle cells and facilitate cell motility. Actin exists initially as globular actin (G-actin) which is converted to filamentous actin (F-actin) upon assembly. The formation of F-actin is a complex multistep process that is tightly regulated by signaling from the actin-binding proteins (ABPs) and Rho family GTPases. Filamentous actin is crosslinked with other actin polymers to form a complex cytoskeletal network which is required for exo- and phagocytosis, vesicular trafficking, cell migration, and gene regulation, among other cellular processes.

Application
