Any process that increases the rate, frequency or extent of the formation of a lamellipodium, a thin sheetlike extension of the surface of a migrating cell.

A series of molecular signals within the cell that are mediated by a member of the Rac family of proteins switching to a GTP-bound active state.

Any process that activates or increases the frequency, rate or extent of protein complex assembly.

An Fc-gamma receptor signaling pathway that contributes to the endocytic engulfment of external particulate material by phagocytes.

Any series of molecular signals initiated by the binding of an extracellular ligand to a vascular endothelial growth factor receptor (VEGFR) located on the surface of the receiving cell, and ending with regulation of a downstream cellular process, e.g. transcription.

The formation of a protein homotrimer, a macromolecular structure consisting of three noncovalently associated identical subunits.

Any process that activates or increases the frequency, rate or extent of Arp2/3 complex-mediated actin nucleation.

Any process that modulates the surface configuration of a cell.

Any process that modulates the frequency, rate or extent of synaptic growth at neuromuscular junctions.

The process in which the anatomical structure of the central nervous system is generated and organized. The central nervous system is the core nervous system that serves an integrating and coordinating function. In vertebrates it consists of the brain and spinal cord. In those invertebrates with a central nervous system it typically consists of a brain, cerebral ganglia and a nerve cord.

The process of creating protein oligomers, compounds composed of a small number, usually between three and ten, of component monomers; protein oligomers may be composed of different or identical monomers. Oligomers may be formed by the polymerization of a number of monomers or the depolymerization of a large protein polymer.

Any process that activates or increases the frequency, rate or extent of the assembly of a filopodium, a thin, stiff protrusion extended by the leading edge of a motile cell such as a crawling fibroblast or amoeba, or an axonal growth cone.

The process whose specific outcome is the progression of the embryo in the uterus over time, from formation of the zygote in the oviduct, to birth. An example of this process is found in Mus musculus.

Any process that activates or increases the rate or extent of cell proliferation.

Any process that increases the rate, frequency or extent of the formation of a lamellipodium, a thin sheetlike extension of the surface of a migrating cell.

A series of molecular signals within the cell that are mediated by a member of the Rac family of proteins switching to a GTP-bound active state.

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 and their associated proteins.

Any process that activates or increases the frequency, rate or extent of protein complex assembly.

Any process involved in the controlled self-propelled movement of a cell that results in translocation of the cell from one place to another.

The formation of a protein homotrimer, a macromolecular structure consisting of three noncovalently associated identical subunits.

Any process that activates or increases the frequency, rate or extent of Arp2/3 complex-mediated actin nucleation.

A pentameric complex that includes orthologues of human PIR121, Nap1, Abi, SCAR, and HSPC300 and regulates actin polymerization and/or depolymerization through small GTPase mediated signal transduction.

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

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

A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.

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

A pentameric complex that includes orthologues of human PIR121, Nap1, Abi, SCAR, and HSPC300 and regulates actin polymerization and/or depolymerization through small GTPase mediated signal transduction.
