Asymmetric Unit(hide GO term definitions)
Chain A,B,C   (PYL2_ARATH | O80992)
molecular function
    GO:0010427    abscisic acid binding    Interacting selectively and non-covalently with abscisic acid, plant hormones that regulate aspects of plant growth.
    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:0042803    protein homodimerization activity    Interacting selectively and non-covalently with an identical protein to form a homodimer.
    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:0004872    receptor activity    Combining with an extracellular or intracellular messenger to initiate a change in cell activity.
biological process
    GO:0009738    abscisic acid-activated signaling pathway    A series of molecular signals generated by the binding of the plant hormone abscisic acid (ABA) to a receptor, and ending with modulation of a cellular process, e.g. transcription.
    GO:0043086    negative regulation of catalytic activity    Any process that stops or reduces the activity of an enzyme.
    GO:0080163    regulation of protein serine/threonine phosphatase activity    Any process that modulates the frequency, rate or extent of protein serine/threonine phosphatase activity: catalysis of the reaction: protein serine/threonine phosphate + H2O = protein serine/threonine + phosphate.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
    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.
