Tropomyosin

Actin filament binding

Coiled-coil protein

Native muscle sources

Strengthening & regulating coiled-coils

Rod-shaped tropomyosin dimers for actin filament stabilization and regulatory studies.

Native actin-binding protein

Tropomyosin for actin filament regulation studies

Native tropomyosin proteins from skeletal or smooth muscle for structural and functional cytoskeleton research.

Tropomyosin forms rod-shaped coiled-coil dimers that associate head-to-tail and bind laterally along the α-helical groove of actin filaments. This interaction stabilizes actin filaments and contributes to the regulation of actin-associated processes in muscle and non-muscle systems.

Coiled-coil structure

Tropomyosin dimers form elongated rod-like structures for filament-side binding.

Actin filament binding

Dimers bind along actin filaments and support studies of filament stabilization and regulation.

Native sources

Available from skeletal, cardiac or smooth muscle sources for actin-based in vitro workflows.
