An endocytosis process that results in the engulfment of external particulate material by phagocytes. The particles are initially contained within phagocytic vacuoles (phagosomes), which then fuse with primary lysosomes to effect digestion of the particles.

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.

Coordinated organization of groups of cells in the plane of an epithelium, such that they all orient to similar coordinates.

An endocytosis process that results in the uptake of liquid material by cells from their external environment; literally 'cell drinking'. Liquid is enclosed in vesicles, called pinosomes, formed by invagination of the plasma membrane.

The directed movement of a motile cell or organism, or the directed growth of a cell guided by a specific chemical concentration gradient. Movement may be towards a higher concentration (positive chemotaxis) or towards a lower concentration (negative chemotaxis).

The directed movement of a border cell through the nurse cells to reach the oocyte. An example of this is found in Drosophila melanogaster.

Any process that modulates the frequency, rate or extent of the assembly of actin filaments by the addition of actin monomers to a filament.

Any process that modulates the frequency, rate or extent of the disassembly of actin filaments by the removal of actin monomers from a filament.

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.

Any process that stops, prevents, or reduces the frequency, rate or extent of actin nucleation mediated by the Arp2/3 complex and interacting proteins.

A process that is carried out at the cellular level that results in the assembly, arrangement of constituent parts, or disassembly of an imaginal disc-derived wing hair. A wing hair is an actin-rich, polarized, non-sensory apical projection that protrudes from each of the approximately 30,000 wing epithelial cells. An example of this is found in Drosophila melanogaster.

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 directed movement of a motile cell or organism in response to the presence of 3',5'-cAMP.

The myofibril assembly process that results in the organization of muscle actomyosin into sarcomeres. The sarcomere is the repeating unit of a myofibril in a muscle cell, composed of an array of overlapping thick and thin filaments between two adjacent Z discs.

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.

Any cleavage furrow formation that is involved in mitotic cell cycle.

The aggregation, arrangement and bonding together of a set of components to form an intranuclear rod.

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

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.

An invagination of the cell membrane formed by an actin dependent process during phagocytosis. Following internalization it is converted into a phagosome.

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.

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.

Any of the various filamentous elements that form the internal framework of cells, and typically remain after treatment of the cells with mild detergent to remove membrane constituents and soluble components of the cytoplasm. The term embraces intermediate filaments, microfilaments, microtubules, the microtrabecular lattice, and other structures characterized by a polymeric filamentous nature and long-range order within the cell. The various elements of the cytoskeleton not only serve in the maintenance of cellular shape but also have roles in other cellular functions, including cellular movement, cell division, endocytosis, and movement of organelles.

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 portion of the cytoskeleton that lies just beneath the plasma membrane.

The portion of the actin cytoskeleton, comprising filamentous actin and associated proteins, that lies just beneath the plasma membrane.

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.

Any complex of actin, myosin, and accessory proteins.

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

A stable macromolecular complex composed (only) of two or more polypeptide subunits along with any covalently attached molecules (such as lipid anchors or oligosaccharide) or non-protein prosthetic groups (such as nucleotides or metal ions). Prosthetic group in this context refers to a tightly bound cofactor. The component polypeptide subunits may be identical.

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

Either of two different areas at opposite ends of an axis of a cell.

A macromolecular fiber consisting of actin and cofilin that is formed in the nucleus as a consequence of chemical or mechanical stress conditions.
