Asymmetric Unit(hide GO term definitions)
Chain A   (CNBL4_ARATH | O81223)
molecular function
    GO:0005509    calcium ion binding    Interacting selectively and non-covalently with calcium ions (Ca2+).
    GO:0004723    calcium-dependent protein serine/threonine phosphatase activity    Catalysis of the reactions: protein serine phosphate + H2O = protein serine + phosphate; and protein threonine phosphate + H2O = protein threonine + phosphate. These reactions require the presence of calcium ions.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    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:0030007    cellular potassium ion homeostasis    Any process involved in the maintenance of an internal steady state of potassium ions at the level of a cell.
    GO:0005513    detection of calcium ion    The series of events in which a calcium ion stimulus is received by a cell and converted into a molecular signal.
    GO:0042539    hypotonic salinity response    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 detection of, or exposure to, a decrease in the concentration of salt (particularly but not exclusively sodium and chloride ions) in the environment.
    GO:0006470    protein dephosphorylation    The process of removing one or more phosphoric residues from a protein.
cellular component
    GO:0005955    calcineurin complex    A heterodimeric calcium ion and calmodulin dependent protein phosphatase composed of catalytic and regulatory subunits; the regulatory subunit is very similar in sequence to calmodulin.
    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.
