NMR Structure(hide GO term definitions)
Chain A   (PP14A_PIG | O18734)
molecular function
    GO:0004864    protein phosphatase inhibitor activity    Stops, prevents or reduces the activity of a protein phosphatase, an enzyme that hydrolyzes phosphate groups from phosphorylated proteins.
    GO:0004865    protein serine/threonine phosphatase inhibitor activity    Stops, prevents or reduces the activity of a serine/threonine protein phosphatase, an enzyme that catalyzes the reaction: protein serine/threonine phosphate + H2O = protein serine/threonine + phosphate.
biological process
    GO:0035690    cellular response to drug    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 drug stimulus. A drug is a substance used in the diagnosis, treatment or prevention of a disease.
    GO:0043086    negative regulation of catalytic activity    Any process that stops or reduces the activity of an enzyme.
    GO:0042325    regulation of phosphorylation    Any process that modulates the frequency, rate or extent of addition of phosphate groups into a molecule.
    GO:0035304    regulation of protein dephosphorylation    Any process that modulates the frequency, rate or extent of removal of phosphate groups from a protein.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
