Chain A   (RASA1_HUMAN | P20936)
molecular function
    GO:0005096    GTPase activator activity    Binds to and increases the activity of a GTPase, an enzyme that catalyzes the hydrolysis of GTP.
    GO:0051020    GTPase binding    Interacting selectively and non-covalently with a GTPase, any enzyme that catalyzes the hydrolysis of GTP.
    GO:0019870    potassium channel inhibitor activity    Stops, prevents, or reduces the activity of a potassium channel.
    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).
    GO:0005102    receptor binding    Interacting selectively and non-covalently with one or more specific sites on a receptor molecule, a macromolecule that undergoes combination with a hormone, neurotransmitter, drug or intracellular messenger to initiate a change in cell function.
biological process
    GO:0000165    MAPK cascade    An intracellular protein kinase cascade containing at least a MAPK, a MAPKK and a MAP3K. The cascade can also contain two additional tiers: the upstream MAP4K and the downstream MAP Kinase-activated kinase (MAPKAPK). The kinases in each tier phosphorylate and activate the kinases in the downstream tier to transmit a signal within a cell.
    GO:0048514    blood vessel morphogenesis    The process in which the anatomical structures of blood vessels are generated and organized. The blood vessel is the vasculature carrying blood.
    GO:0009790    embryo development    The process whose specific outcome is the progression of an embryo from its formation until the end of its embryonic life stage. The end of the embryonic stage is organism-specific. For example, for mammals, the process would begin with zygote formation and end with birth. For insects, the process would begin at zygote formation and end with larval hatching. For plant zygotic embryos, this would be from zygote formation to the end of seed dormancy. For plant vegetative embryos, this would be from the initial determination of the cell or group of cells to form an embryo until the point when the embryo becomes independent of the parent plant.
    GO:0048013    ephrin receptor signaling pathway    The series of molecular signals generated as a consequence of an ephrin receptor binding to an ephrin.
    GO:0035556    intracellular signal transduction    The process in which a signal is passed on to downstream components within the cell, which become activated themselves to further propagate the signal and finally trigger a change in the function or state of the cell.
    GO:0000281    mitotic cytokinesis    A cell cycle process that results in the division of the cytoplasm of a cell after mitosis, resulting in the separation of the original cell into two daughter cells.
    GO:0046580    negative regulation of Ras protein signal transduction    Any process that stops, prevents, or reduces the frequency, rate or extent of Ras protein signal transduction.
    GO:0007162    negative regulation of cell adhesion    Any process that stops, prevents, or reduces the frequency, rate or extent of cell adhesion.
    GO:0001953    negative regulation of cell-matrix adhesion    Any process that stops, prevents, or reduces the rate or extent of cell adhesion to the extracellular matrix.
    GO:0043524    negative regulation of neuron apoptotic process    Any process that stops, prevents, or reduces the frequency, rate or extent of cell death by apoptotic process in neurons.
    GO:0043547    positive regulation of GTPase activity    Any process that activates or increases the activity of a GTPase.
    GO:0043087    regulation of GTPase activity    Any process that modulates the rate of GTP hydrolysis by a GTPase.
    GO:0051252    regulation of RNA metabolic process    Any process that modulates the frequency, rate or extent of the chemical reactions and pathways involving RNA.
    GO:0030833    regulation of actin filament polymerization    Any process that modulates the frequency, rate or extent of the assembly of actin filaments by the addition of actin monomers to a filament.
    GO:0008360    regulation of cell shape    Any process that modulates the surface configuration of a cell.
    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:0001570    vasculogenesis    The differentiation of endothelial cells from progenitor cells during blood vessel development, and the de novo formation of blood vessels and tubes.
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:0031235    intrinsic component of the cytoplasmic side of the plasma membrane    The component of a plasma membrane consisting of gene products and protein complexes that have some covalently attached part (e.g. peptide sequence or GPI anchor) which is embedded in the cytoplasmic side of the plasma membrane only.
    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.
    GO:0001726    ruffle    Projection at the leading edge of a crawling cell; the protrusions are supported by a microfilament meshwork.
