What mechanisms drive cytoskeleton extension within podosomes?
What mechanisms drive cytoskeleton extension within podosomes? Interactions between the extracellular matrix (ECM) and cell surface integrins leads to podosome formation. The initiating signal is transduced through mechanosensing integrins to the cytoskeleton, upon which [...]
What are stress fibers?
What are stress fibers? Stress fibers are higher order cytoskeletal structures composed of cross-linked actin filament bundles, and in many cases, myosin motor proteins, that span a length of 1-2 micrometers [1]. At least [...]
What is the function of stress fibers?
What is the function of stress fibers? Stress fibers are contractile in nature. By exerting and maintaining tension on the underlying substratum, they form a key element of the mechanotransduction apparatus that links the [...]
What is Myosin?
What is Myosin? An Introduction to the Myosin Superfamily of Proteins Myosin I has unique tail domain(s) relative to other myosin members which allows myosin I to bind to membrane lipids or to more [...]
How do motor proteins transport cargo along the cytoskeleton?
How do motor proteins transport cargo along the cytoskeleton? Along with providing structural support to the cell, and transmitting force signals, cytoskeletal filaments also provide cells with a network of ‘tracks’ that can be [...]
What are Motor Proteins?
What are Motor Proteins? Motor proteins, such as myosins and kinesins, move along cytoskeletal filaments via a force-dependent mechanism that is driven by the hydrolysis of ATP molecules (reviewed in [1]). Nucleotide hydrolysis and [...]
