The process of introducing a phosphate group on to a protein.

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

An actin filament severing process that results in the removal of actin filament branches specifically at the branch points.

Assembly of an actin cortical patch, a discrete actin-containing structure found at the plasma membrane of fungal cells.

The extension of new blood vessels from existing capillaries into avascular tissues resulting from the proliferation of blood vessel endothelial cells.

The cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. Signal transduction begins with reception of a signal (e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light), or for signal transduction in the absence of ligand, signal-withdrawal or the activity of a constitutively active receptor. Signal transduction ends with regulation of a downstream cellular process, e.g. regulation of transcription or regulation of a metabolic process. Signal transduction covers signaling from receptors located on the surface of the cell and signaling via molecules located within the cell. For signaling between cells, signal transduction is restricted to events at and within the receiving cell.

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

The process whose specific outcome is the progression of nervous tissue over time, from its formation to its mature state.

Any process in an organism in which a relatively long-lasting adaptive behavioral change occurs as the result of experience.

The specific movement from place to place of an organism in response to external or internal stimuli. Locomotion of a whole organism in a manner dependent upon some combination of that organism's internal state and external conditions.

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 a process involved in the formation, arrangement of constituent parts, or disassembly of cell projections.

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

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

The regulated exocytosis of secretory granules containing preformed mediators such as proteases, lipases, and inflammatory mediators by a neutrophil.

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.

The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.

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

A thin sheetlike process extended by the leading edge of a migrating cell or extending cell process; contains a dense meshwork of actin filaments.

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 volume enclosed by the membrane of a secretory granule.

Cytoplasm situated near, or occurring around, the nucleus.

The part of a cell encompassing the cell cortex, the plasma membrane, and any external encapsulating structures.

Any membrane-enclosed lumen that is part of a ficolin-1-rich granule.
