When that protein is added to the receptor, the receptor gets taken out of its nanodomain and becomes caught up in the actin filaments that form the cell's cytoskeleton.

The junction moves from the front to the rear of the protozoan, probably powered by actin and myosin protein filaments, like those in human muscle, constricting the protozoan and pulling the host membrane over it.

Actin allows vital actions to be performed by assembling and disassembling itself spontaneously, continually and rapidly in the form of filaments that organize themselves and form networks of parallel bundles or intertwined meshes (known as lamellar networks).

A group of plant biologists at the Institute of Transformative Bio-Molecules (ITbM) of Nagoya University, the University of Tokyo, the Gregor Mendel Institute, and the University of Kentucky, has reported in the journal Proceedings of the National Academy of Sciences, on their discovery on how the plant's egg cells initially lose their skeletal pattern upon fertilization and are reorganized by two major cytoskeleton components in the cell, microtubules (MTs) and actin filaments (F - actin).

Higher magnifications of ultrathin sections shown in C and G indicate the presence of electron - dense DAB precipitates adjacent to F - actin filaments.

Actin, the protein that makes up the cytoskeleton, can form long filaments that grow in one direction and networks of filaments.

Providing rigidity to the cell, actin filaments are involved in a host of processes including muscle contraction, cell mobility and cell division.

Beads coated with Arp2 / 3 - activating proteins can induce two distinct types of actin organization in cytoplasmic extracts: (1) comet tails or clouds displaying a dendritic array of actin filaments and (2) stars with filament bundles radiating from the bead.

Much of this dynamic happens in close proximity to the plasma membrane due to the fact that actin assembly factors are membrane - bound, and thus actin filaments are generally oriented such that their growth occurs against or near the membrane.

On the basis of analysis of this system, we proposed a model for filopodial formation in which actin filaments of a preexisting dendritic network are elongated by inhibition of capping and subsequently cross-linked into bundles by fascin.
