Asymmetric Unit(hide GO term definitions)
Chain A,B   (SGK3_MOUSE | Q9ERE3)
molecular function
    GO:0005524    ATP binding    Interacting selectively and non-covalently with ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
    GO:0005246    calcium channel regulator activity    Modulates the activity of a calcium channel.
    GO:0017081    chloride channel regulator activity    Modulates the activity of a chloride channel.
    GO:0016301    kinase activity    Catalysis of the transfer of a phosphate group, usually from ATP, to a substrate molecule.
    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:0035091    phosphatidylinositol binding    Interacting selectively and non-covalently with any inositol-containing glycerophospholipid, i.e. phosphatidylinositol (PtdIns) and its phosphorylated derivatives.
    GO:0015459    potassium channel regulator activity    Modulates potassium channel activity via direct interaction interaction with a potassium channel (binding or modification).
    GO:0004672    protein kinase activity    Catalysis of the phosphorylation of an amino acid residue in a protein, usually according to the reaction: a protein + ATP = a phosphoprotein + ADP.
    GO:0004674    protein serine/threonine kinase activity    Catalysis of the reactions: ATP + protein serine = ADP + protein serine phosphate, and ATP + protein threonine = ADP + protein threonine phosphate.
    GO:0017080    sodium channel regulator activity    Modulates the activity of a sodium channel.
    GO:0016740    transferase activity    Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.
biological process
    GO:0006883    cellular sodium ion homeostasis    Any process involved in the maintenance of an internal steady state of sodium ions at the level of a cell.
    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:2001240    negative regulation of extrinsic apoptotic signaling pathway in absence of ligand    Any process that stops, prevents or reduces the frequency, rate or extent of extrinsic apoptotic signaling pathway in absence of ligand.
    GO:0018105    peptidyl-serine phosphorylation    The phosphorylation of peptidyl-serine to form peptidyl-O-phospho-L-serine.
    GO:0016310    phosphorylation    The process of introducing a phosphate group into a molecule, usually with the formation of a phosphoric ester, a phosphoric anhydride or a phosphoric amide.
    GO:0010765    positive regulation of sodium ion transport    Any process that increases the frequency, rate or extent of the directed movement of sodium ions (Na+) into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
    GO:0032411    positive regulation of transporter activity    Any process that activates or increases the activity of a transporter.
    GO:0006468    protein phosphorylation    The process of introducing a phosphate group on to a protein.
    GO:0001558    regulation of cell growth    Any process that modulates the frequency, rate, extent or direction of cell growth.
    GO:0042127    regulation of cell proliferation    Any process that modulates the frequency, rate or extent of cell proliferation.
cellular component
    GO:0031410    cytoplasmic vesicle    A vesicle found in the cytoplasm of a cell.
    GO:0005769    early endosome    A membrane-bounded organelle that receives incoming material from primary endocytic vesicles that have been generated by clathrin-dependent and clathrin-independent endocytosis; vesicles fuse with the early endosome to deliver cargo for sorting into recycling or degradation pathways.
    GO:0005768    endosome    A vacuole to which materials ingested by endocytosis are delivered.
    GO:0055037    recycling endosome    An organelle consisting of a network of tubules that functions in targeting molecules, such as receptors transporters and lipids, to the plasma membrane.
