Chain A   (STE50_YEAST | P25344)
molecular function
    GO:0032093    SAM domain binding    Interacting selectively and non-covalently with a SAM (Sterile Alpha Motif) domain, which is a 70-amino acid protein sequence that participates in protein-protein, protein-lipid, and protein-RNA interactions and is conserved from lower to higher eukaryotes.
    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:0019887    protein kinase regulator activity    Modulates the activity of a protein kinase, an enzyme which phosphorylates a protein.
biological process
    GO:0000161    MAPK cascade involved in osmosensory signaling pathway    A MAPK cascade involved in signal transduction in response to change in osmotic conditions.
    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:0034605    cellular response to heat    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 a heat stimulus, a temperature stimulus above the optimal temperature for that organism.
    GO:0007232    osmosensory signaling pathway via Sho1 osmosensor    A series of molecular signals generated in response to osmotic change, as mediated through a Sho1 osmosensor system.
    GO:0000750    pheromone-dependent signal transduction involved in conjugation with cellular fusion    A signal transduction process resulting in the relay, amplification or dampening of a signal generated in response to pheromone exposure in organisms that undergo conjugation with cellular fusion. An example of this process is found in Saccharomyces cerevisiae.
    GO:0045859    regulation of protein kinase activity    Any process that modulates the frequency, rate or extent of protein kinase activity.
    GO:0019236    response to pheromone    Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a pheromone stimulus.
    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:0001402    signal transduction involved in filamentous growth    Relaying of environmental signals promoting filamentous growth.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
