Chain A,E   (ARHGB_HUMAN | O15085)
molecular function
    GO:0001664    G-protein coupled receptor binding    Interacting selectively and non-covalently with a G-protein coupled receptor.
    GO:0005096    GTPase activator activity    Binds to and increases the activity of a GTPase, an enzyme that catalyzes the hydrolysis of GTP.
    GO:0005089    Rho guanyl-nucleotide exchange factor activity    Stimulates the exchange of guanyl nucleotides associated with a GTPase of the Rho family. Under normal cellular physiological conditions, the concentration of GTP is higher than that of GDP, favoring the replacement of GDP by GTP in association with the GTPase.
    GO:0005085    guanyl-nucleotide exchange factor activity    Stimulates the exchange of guanyl nucleotides associated with a GTPase. Under normal cellular physiological conditions, the concentration of GTP is higher than that of GDP, favoring the replacement of GDP by GTP in association with the GTPase.
    GO:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
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:0007266    Rho protein signal transduction    A series of molecular signals within the cell that are mediated by a member of the Rho family of proteins switching to a GTP-bound active state.
    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:0000910    cytokinesis    The division of the cytoplasm and the plasma membrane of a cell and its partitioning into two daughter cells.
    GO:0030010    establishment of cell polarity    The specification and formation of anisotropic intracellular organization or cell growth patterns.
    GO:0006928    movement of cell or subcellular component    The directed, self-propelled movement of a cell or subcellular component without the involvement of an external agent such as a transporter or a pore.
    GO:0043547    positive regulation of GTPase activity    Any process that activates or increases the activity of a GTPase.
    GO:0043065    positive regulation of apoptotic process    Any process that activates or increases the frequency, rate or extent of cell death by apoptotic process.
    GO:0045893    positive regulation of transcription, DNA-templated    Any process that activates or increases the frequency, rate or extent of cellular DNA-templated transcription.
    GO:0035023    regulation of Rho protein signal transduction    Any process that modulates the frequency, rate or extent of Rho protein signal transduction.
    GO:0001558    regulation of cell growth    Any process that modulates the frequency, rate, extent or direction of cell growth.
    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:0006941    striated muscle contraction    A process in which force is generated within striated muscle tissue, resulting in the shortening of the muscle. Force generation involves a chemo-mechanical energy conversion step that is carried out by the actin/myosin complex activity, which generates force through ATP hydrolysis. Striated muscle is a type of muscle in which the repeating units (sarcomeres) of the contractile myofibrils are arranged in registry throughout the cell, resulting in transverse or oblique striations observable at the level of the light microscope.
cellular component
    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:0005622    intracellular    The living contents of a cell; the matter contained within (but not including) the plasma membrane, usually taken to exclude large vacuoles and masses of secretory or ingested material. In eukaryotes it includes the nucleus and cytoplasm.
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.

Chain B,F   (RHOA_HUMAN | P61586)
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:0017022    myosin binding    Interacting selectively and non-covalently with any part of a myosin complex; myosins are any of a superfamily of molecular motor proteins that bind to actin and use the energy of ATP hydrolysis to generate force and movement along actin filaments.
    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:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
biological process
    GO:0007266    Rho protein signal transduction    A series of molecular signals within the cell that are mediated by a member of the Rho family of proteins switching to a GTP-bound active state.
    GO:0035385    Roundabout signaling pathway    A series of molecular signals initiated by the binding of a SLIT protein to a Roundabout (ROBO) family receptor on the surface of a target cell, and ending with regulation of a downstream cellular process, e.g. transcription.
    GO:0060071    Wnt signaling pathway, planar cell polarity pathway    The series of molecular signals initiated by binding of a Wnt protein to a receptor on the surface of the target cell where activated receptors signal via downstream effectors including C-Jun N-terminal kinase (JNK) to modulate cytoskeletal elements and control cell polarity.
