Chain A   (RAC2_HUMAN | P15153)
molecular function
    GO:0005525    GTP binding    Interacting selectively and non-covalently with GTP, guanosine triphosphate.
    GO:0003924    GTPase activity    Catalysis of the reaction: GTP + H2O = GDP + phosphate.
    GO:0000166    nucleotide binding    Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose.
    GO:0019887    protein kinase regulator activity    Modulates the activity of a protein kinase, an enzyme which phosphorylates a protein.
biological process
    GO:0007186    G-protein coupled receptor signaling pathway    A series of molecular signals that proceeds with an activated receptor promoting the exchange of GDP for GTP on the alpha-subunit of an associated heterotrimeric G-protein complex. The GTP-bound activated alpha-G-protein then dissociates from the beta- and gamma-subunits to further transmit the signal within the cell. The pathway begins with receptor-ligand interaction, or for basal GPCR signaling the pathway begins with the receptor activating its G protein in the absence of an agonist, and ends with regulation of a downstream cellular process, e.g. transcription. The pathway can start from the plasma membrane, Golgi or nuclear membrane (PMID:24568158 and PMID:16902576).
    GO:0030036    actin cytoskeleton organization    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.
    GO:0007015    actin filament organization    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.
    GO:0045453    bone resorption    The process in which specialized cells known as osteoclasts degrade the organic and inorganic portions of bone, and endocytose and transport the degradation products.
    GO:0030031    cell projection assembly    Formation of a prolongation or process extending from a cell, e.g. a flagellum or axon.
    GO:0006935    chemotaxis    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).
    GO:0071593    lymphocyte aggregation    The adhesion of one lymphocyte to one or more other lymphocytes via adhesion molecules.
    GO:0030168    platelet activation    A series of progressive, overlapping events triggered by exposure of the platelets to subendothelial tissue. These events include shape change, adhesiveness, aggregation, and release reactions. When carried through to completion, these events lead to the formation of a stable hemostatic plug.
    GO:0008284    positive regulation of cell proliferation    Any process that activates or increases the rate or extent of cell proliferation.
    GO:0010592    positive regulation of lamellipodium assembly    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.
    GO:0090023    positive regulation of neutrophil chemotaxis    Any process that increases the frequency, rate, or extent of neutrophil chemotaxis. Neutrophil chemotaxis is the directed movement of a neutrophil cell, the most numerous polymorphonuclear leukocyte found in the blood, in response to an external stimulus, usually an infection or wounding.
    GO:1903955    positive regulation of protein targeting to mitochondrion    Any process that activates or increases the frequency, rate or extent of protein targeting to mitochondrion.
    GO:0042129    regulation of T cell proliferation    Any process that modulates the frequency, rate or extent of T cell proliferation.
    GO:0010810    regulation of cell-substrate adhesion    Any process that modulates the frequency, rate or extent of cell-substrate adhesion. Cell-substrate adhesion is the attachment of a cell to the underlying substrate via adhesion molecules.
    GO:0010310    regulation of hydrogen peroxide metabolic process    Any process that modulates the frequency, rate or extent of the chemical reactions and pathways involving hydrogen peroxide.
    GO:0060753    regulation of mast cell chemotaxis    Any process that modulates the rate, frequency or extent of mast cell chemotaxis. Mast cell chemotaxis is the movement of a mast cell in response to an external stimulus.
    GO:0043304    regulation of mast cell degranulation    Any process that modulates the frequency, rate, or extent of mast cell degranulation.
    GO:1902622    regulation of neutrophil migration    Any process that modulates the frequency, rate or extent of neutrophil migration.
    GO:0045859    regulation of protein kinase activity    Any process that modulates the frequency, rate or extent of protein kinase activity.
    GO:0060263    regulation of respiratory burst    Any process that modulates the rate frequency or extent of a phase of elevated metabolic activity, during which oxygen consumption increases; this leads to the production, by an NADH dependent system, of hydrogen peroxide (H2O2), superoxide anions and hydroxyl radicals.
    GO:0051056    regulation of small GTPase mediated signal transduction    Any process that modulates the frequency, rate or extent of small GTPase mediated signal transduction.
    GO:0007165    signal transduction    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.
    GO:0007264    small GTPase mediated signal transduction    Any series of molecular signals in which a small monomeric GTPase relays one or more of the signals.
cellular component
    GO:0005884    actin filament    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.
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
    GO:0070062    extracellular exosome    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.
    GO:0005925    focal adhesion    Small region on the surface of a cell that anchors the cell to the extracellular matrix and that forms a point of termination of actin filaments.
    GO:0030027    lamellipodium    A thin sheetlike process extended by the leading edge of a migrating cell or extending cell process; contains a dense meshwork of actin filaments.
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
    GO:0005635    nuclear envelope    The double lipid bilayer enclosing the nucleus and separating its contents from the rest of the cytoplasm; includes the intermembrane space, a gap of width 20-40 nm (also called the perinuclear space).
    GO:0030670    phagocytic vesicle membrane    The lipid bilayer surrounding a phagocytic vesicle.
    GO:0005886    plasma membrane    The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
