    GO:0071476    cellular hypotonic response    Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of detection of, or exposure to, a hypotonic environment, i.e. an environment with a lower concentration of solutes than the organism or 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:1901380    negative regulation of potassium ion transmembrane transport    Any process that stops, prevents or reduces the frequency, rate or extent of potassium ion transmembrane transport.
    GO:1901017    negative regulation of potassium ion transmembrane transporter activity    Any process that stops, prevents or reduces the frequency, rate or extent of potassium ion transmembrane transporter activity.

    GO:0018105    peptidyl-serine phosphorylation    The phosphorylation of peptidyl-serine to form peptidyl-O-phospho-L-serine.
    GO:0010800    positive regulation of peptidyl-threonine phosphorylation    Any process that increases the frequency, rate or extent of peptidyl-threonine phosphorylation. Peptidyl-threonine phosphorylation is the phosphorylation of peptidyl-threonine to form peptidyl-O-phospho-L-threonine.
    GO:0071902    positive regulation of protein serine/threonine kinase activity    Any process that increases the rate, frequency, or extent of protein serine/threonine kinase activity.
    GO:0051291    protein heterooligomerization    The process of creating protein oligomers, compounds composed of a small number, usually between three and ten, of component monomers that are not all identical. Oligomers may be formed by the polymerization of a number of monomers or the depolymerization of a large protein polymer.
    GO:0006468    protein phosphorylation    The process of introducing a phosphate group on to a protein.
    GO:0023014    signal transduction by protein phosphorylation    A process in which the transfer of one or more phosphate groups to a substrate transmits a signal to the phosphorylated substrate.
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: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:0043234    protein complex    A stable macromolecular complex composed (only) of two or more polypeptide subunits along with any covalently attached molecules (such as lipid anchors or oligosaccharide) or non-protein prosthetic groups (such as nucleotides or metal ions). Prosthetic group in this context refers to a tightly bound cofactor. The component polypeptide subunits may be identical.
    GO:1902554    serine/threonine protein kinase complex    A protein complex which is capable of protein serine/threonine kinase activity.

Chain B   (STRAA_HUMAN | Q7RTN6)
molecular function

    GO:0019900    kinase binding    Interacting selectively and non-covalently with a kinase, any enzyme that catalyzes the transfer of a phosphate group.
    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:0032147    activation of protein kinase activity    Any process that initiates the activity of an inactive protein kinase.
    GO:0007049    cell cycle    The progression of biochemical and morphological phases and events that occur in a cell during successive cell replication or nuclear replication events. Canonically, the cell cycle comprises the replication and segregation of genetic material followed by the division of the cell, but in endocycles or syncytial cells nuclear replication or nuclear division may not be followed by cell division.
    GO:0007050    cell cycle arrest    A regulatory process that halts progression through the cell cycle during one of the normal phases (G1, S, G2, M).
    GO:0071902    positive regulation of protein serine/threonine kinase activity    Any process that increases the rate, frequency, or extent of protein serine/threonine kinase activity.
