Chain A,B   (RGS3_HUMAN | P49796)
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: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:0000188    inactivation of MAPK activity    Any process that terminates the activity of the active enzyme MAP kinase.
    GO:0009968    negative regulation of signal transduction    Any process that stops, prevents, or reduces the frequency, rate or extent of signal transduction.
    GO:0043547    positive regulation of GTPase activity    Any process that activates or increases the activity of a GTPase.
    GO:0008277    regulation of G-protein coupled receptor protein signaling pathway    Any process that modulates the frequency, rate or extent of G-protein coupled receptor protein signaling pathway activity.
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:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
    GO:0005654    nucleoplasm    That part of the nuclear content other than the chromosomes or the nucleolus.
    GO:0005634    nucleus    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.
    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.
