Disassembly of actin filaments by the removal of actin monomers from a filament.

Disassembly of actin filaments by the removal of actin monomers from a filament.

Any process that stops, prevents, or reduces the frequency, rate or extent of the division of the cytoplasm of a cell, and its separation into two daughter cells.

The binding of a protein or protein complex to the barbed (or plus) end of an actin filament, thus preventing the addition, exchange or removal of further actin subunits.

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of cytoskeletal structures comprising actin filaments. Includes processes that control the spatial distribution of actin filaments, such as organizing filaments into meshworks, bundles, or other structures, as by cross-linking.

Disassembly of actin filaments by the removal of actin monomers from a filament.

The aggregation, arrangement and bonding together of proteins to form the actin-based thin filaments of myofibrils in skeletal muscle.

Any process that activates or increases the frequency, rate or extent of actin depolymerization.

Any process that stops, prevents, or reduces the frequency, rate or extent of actin polymerization.

Any process that modulates the frequency, rate or extent of any process in which a protein is transported to, or maintained in, a specific location.

Self-propelled movement of a cell or organism from one location to another.

Self-propelled movement of a cell or organism from one location to another.

Any process that modulates the frequency, rate or extent of locomotion of a cell or organism.

Any process that modulates the frequency, rate or extent of locomotion of a cell or organism.

The aggregation, arrangement and bonding together of proteins to form the actin-based thin filaments of myofibrils in striated muscle.

The aggregation, arrangement and bonding together of proteins to form the actin-based thin filaments of myofibrils in striated muscle.

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

A filamentous structure formed of a two-stranded helical polymer of the protein actin and associated proteins. Actin filaments are a major component of the contractile apparatus of skeletal muscle and the microfilaments of the cytoskeleton of eukaryotic cells. The filaments, comprising polymerized globular actin molecules, appear as flexible structures with a diameter of 5-9 nm. They are organized into a variety of linear bundles, two-dimensional networks, and three dimensional gels. In the cytoskeleton they are most highly concentrated in the cortex of the cell just beneath the plasma membrane.

An endocytic patch that consists of an actin-containing structure found at the plasma membrane in cells; formed of networks of branched actin filaments that lie just beneath the plasma membrane and assemble, move, and disassemble rapidly. An example of this is the actin cortical patch found in Saccharomyces cerevisiae.

The apex of the mating projection in unicellular fungi exposed to mating pheromone; site of polarized growth.

A ubiquitin ligase complex in which a cullin from the Cul4 family and a RING domain protein form the catalytic core; substrate specificity is conferred by an adaptor protein.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

The cytoplasm of a muscle cell; includes the sarcoplasmic reticulum.

The contractile element of skeletal and cardiac muscle; a long, highly organized bundle of actin, myosin, and other proteins that contracts by a sliding filament mechanism.

An endocytic patch that consists of an actin-containing structure found at the plasma membrane in cells; formed of networks of branched actin filaments that lie just beneath the plasma membrane and assemble, move, and disassemble rapidly. An example of this is the actin cortical patch found in Saccharomyces cerevisiae.

The eventual plane of cell division (also known as cell cleavage or cytokinesis) in a dividing cell. In Eukaryotes, the cleavage apparatus, composed of septin structures and the actomyosin contractile ring, forms along this plane, and the mitotic, or meiotic, spindle is aligned perpendicular to the division plane. In bacteria, the cell division site is generally located at mid-cell and is the site at which the cytoskeletal structure, the Z-ring, assembles.

The actin part of any complex of actin, myosin, and accessory proteins.

The region at the end of the longest axis of a cylindrical or elongated cell.
