A process that results in the assembly, arrangement of constituent parts, or disassembly of an actin filament bundle.

The aggregation, arrangement and bonding together of a set of components to form a formin-nucleated actin cable. A formin-nucleated actin cable is an actin filament bundle that consists of short filaments organized into bundles of uniform polarity, and is nucleated by formins.

A cell cycle process that results in the division of the cytoplasm of a cell after mitosis, resulting in the separation of the original cell into two daughter cells.

Movement of a vesicle along an actin filament, mediated by motor proteins.

A process of actin filament bundle distribution that results in the arrangement of actin filament bundles from the periphery toward the interior of the cell.

Any cellular process that results in the specification, formation or maintenance of a polarized intracellular organization or cell growth patterns that regulate the shape of a cell.

Any actomyosin contractile ring assembly that is involved in mitotic cytokinesis.

Any actin filament bundle convergence that is involved in mitotic actomyosin contractile ring assembly.

A process in which a protein is transported to, or maintained in, a location within an actin fusion focus.

A process in which a protein is transported to, or maintained in, a location within an actin fusion focus.

A process in which a protein is transported to, or maintained in, the cell cortex of the cell tip.

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.

A focus at the mating projection tip where the cell wall is degraded during conjugation with cellular fusion. Actin filaments form an aster-like structure from this location.

A cytoskeletal structure composed of actin filaments and myosin that forms beneath the plasma membrane of many cells, including animal cells and yeast cells, in a plane perpendicular to the axis of the spindle, i.e. the cell division plane. In animal cells, the contractile ring is located at the cleavage furrow. In budding fungal cells, e.g. mitotic S. cerevisiae cells, the contractile ring forms at the mother-bud neck before mitosis.

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

A protein complex, formed of one or more myosin heavy chains plus associated light chains and other proteins, that functions as a molecular motor; uses the energy of ATP hydrolysis to move actin filaments or to move vesicles or other cargo on fixed actin filaments; has magnesium-ATPase activity and binds actin. Myosin classes are distinguished based on sequence features of the motor, or head, domain, but also have distinct tail regions that are believed to bind specific cargoes.

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.

A medial cortical band overlaying the nucleus which acts as a landmark for contractile ring positioning and plays a role in cell cycle regulation.

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 region directly beneath the plasma membrane at the cell tip. The cell tip is the region at either end of the longest axis of a cylindrical or elongated cell.

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

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

An actin filament bundle that consists of short filaments organized into bundles of uniform polarity, and is nucleated by formins. In fungal cells, myosin motors transport cargo along actin cables toward sites of polarized cell growth; actin cables may play a similar role in pollen tube growth.

A region of the cell cortex that contains a higher concentration of growth polarity factors than the surrounding cortex and that changes position over time. An example is found in fission yeast cells during early mating, in which the GTPase Cdc42 dynamically to discrete zones within the cortex prior to shmoo formation.

The region directly beneath the plasma membrane of the lateral portion of the cell.

The region of the actomyosin ring adjacent to the plasma membrane where membrane bound scaffolds are located.

Any cell cortex that is part of a growing cell tip.
