Specificity:

Anti-Human Actin Bundles (Clone AE-7) recognizes and antigen associated with human actin bundles. The sequence of the epitope is unmapped.

Background:

Microfilaments (or actin filaments) are the thinnest filaments of the cytoskeleton found in the cytoplasm of all eukaryotic cells. These linear polymers of actin subunits are flexible and relatively strong, resisting buckling by multi-piconewton compressive forces and filament fracture by nanonewton tensile forces. Microfilaments are highly versatile, functioning in (a) actoclampin-driven expansile molecular motors, where each elongating filament harnesses the hydrolysis energy of its "on-board" ATP to drive actoclampin end-tracking motors to propel cell crawling, ameboid movement, and changes in cell shape, and (b) actomyosin-driven contractile molecular motors, where the thin filaments serve as tensile platforms for myosin's ATP hydrolysis-dependent pulling action in muscle contraction and uropod advancement.Actin filaments are assembled in two general types of structures: bundles and networks. Actin-binding proteins dictate the formation of either structure since they cross-link actin filaments in the double-stranded helix.
