Chain A   (CNBL2_ARATH | Q8LAS7)
molecular function
    GO:0005509    calcium ion binding    Interacting selectively and non-covalently with calcium ions (Ca2+).
    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:0019722    calcium-mediated signaling    Any intracellular signal transduction in which the signal is passed on within the cell via calcium ions.
    GO:0055075    potassium ion homeostasis    Any process involved in the maintenance of an internal steady state of potassium ions within an organism or cell.
cellular component
    GO:0022626    cytosolic ribosome    A ribosome located in the cytosol.
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
    GO:0009705    plant-type vacuole membrane    The lipid bilayer surrounding a vacuole that retains the same shape regardless of cell cycle phase. The membrane separates its contents from the cytoplasm of the cell. An example of this component is found in Arabidopsis thaliana.
    GO:0005774    vacuolar membrane    The lipid bilayer surrounding the vacuole and separating its contents from the cytoplasm of the cell.
    GO:0005773    vacuole    A closed structure, found only in eukaryotic cells, that is completely surrounded by unit membrane and contains liquid material. Cells contain one or several vacuoles, that may have different functions from each other. Vacuoles have a diverse array of functions. They can act as a storage organelle for nutrients or waste products, as a degradative compartment, as a cost-effective way of increasing cell size, and as a homeostatic regulator controlling both turgor pressure and pH of the cytosol.
