  2. Microfilament - Wikipedia

    en.wikipedia.org/wiki/Microfilament

    Microfilament functions include cytokinesis, amoeboid movement, cell motility, changes in cell shape, endocytosis and exocytosis, cell contractility, and mechanical stability. Microfilaments are flexible and relatively strong, resisting buckling by multi-piconewton compressive forces and filament fracture by nanonewton tensile forces.

  3. Cytoskeleton - Wikipedia

    en.wikipedia.org/wiki/Cytoskeleton

    Microfilaments, also known as actin filaments, are composed of linear polymers of G-actin proteins, and generate force when the growing (plus) end of the filament pushes against a barrier, such as the cell membrane. They also act as tracks for the movement of myosin molecules that affix to the microfilament and "walk" along them. In general ...

  4. Protein filament - Wikipedia

    en.wikipedia.org/wiki/Protein_filament

    Microfilament Polymerization. Microfilament polymerization is divided into three steps. The nucleation step is the first step, and it is the rate limiting and slowest step of the process. Elongation is the next step in this process, and it is the rapid addition of actin monomers at both the plus and minus end of the microfilament.

  6. Axoneme - Wikipedia

    en.wikipedia.org/wiki/Axoneme

    Inside a cilium and a flagellum is a microtubule-based cytoskeleton called the axoneme. The axoneme of a primary cilium typically has a ring of nine outer microtubule doublets (called a 9+0 axoneme), and the axoneme of a motile cilium has two central microtubules in addition to the nine outer doublets (called a 9+2 axoneme).

  7. Actin - Wikipedia

    en.wikipedia.org/wiki/Actin

    Actin is a family of globular multi-functional proteins that form microfilaments in the cytoskeleton, and the thin filaments in muscle fibrils.It is found in essentially all eukaryotic cells, where it may be present at a concentration of over 100 μM; its mass is roughly 42 kDa, with a diameter of 4 to 7 nm.

  9. Stress fiber - Wikipedia

    en.wikipedia.org/wiki/Stress_fiber

    Stress fibers are contractile actin bundles found in non-muscle cells. [1] They are composed of actin (microfilaments) and non-muscle myosin II (NMMII), and also contain various crosslinking proteins, such as α-actinin, to form a highly regulated actomyosin structure within non-muscle cells. [2]
