Chain A,B   (PHOU_AQUAE | O67053)
molecular function
    GO:0005315    inorganic phosphate transmembrane transporter activity    Enables the transfer of a inorganic phosphate from one side of a membrane to the other, up its concentration gradient. The transporter binds the solute and undergoes a series of conformational changes. Transport works equally well in either direction and is driven by a chemiosmotic source of energy. Chemiosmotic sources of energy include uniport, symport or antiport.
    GO:0042803    protein homodimerization activity    Interacting selectively and non-covalently with an identical protein to form a homodimer.
    GO:0015321    sodium-dependent phosphate transmembrane transporter activity    Enables the transfer of phosphate (PO4 3-) ions from one side of a membrane to the other, requiring sodium ions.
    GO:0005436    sodium:phosphate symporter activity    Catalysis of the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: Na+(out) + phosphate(out) = Na+(in) + phosphate(in).
biological process
    GO:0030643    cellular phosphate ion homeostasis    Any process involved in the maintenance of an internal steady state of phosphate ions at the level of a cell.
    GO:0010629    negative regulation of gene expression    Any process that decreases the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA or circRNA (for protein-coding genes) and the translation of that mRNA or circRNA into protein. Protein maturation is included when required to form an active form of a product from an inactive precursor form.
    GO:0045936    negative regulation of phosphate metabolic process    Any process that stops, prevents, or reduces the frequency, rate or extent of the chemical reactions and pathways involving phosphates.
    GO:2000186    negative regulation of phosphate transmembrane transport    Any process that stops, prevents, or reduces the frequency, rate or extent of phosphate transmembrane transport.
    GO:0035435    phosphate ion transmembrane transport    The directed movement of phosphate across a membrane by means of some agent such as a transporter or pore.
    GO:0006817    phosphate ion transport    The directed movement of phosphate into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
    GO:0035725    sodium ion transmembrane transport    A process in which a sodium ion is transported from one side of a membrane to the other by means of some agent such as a transporter or pore.
    GO:0044341    sodium-dependent phosphate transport    The directed movement of phosphate into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore, by a mechanism dependent upon sodium ions.
    GO:0055085    transmembrane transport    The process in which a solute is transported across a lipid bilayer, from one side of a membrane to the other
    GO:0006810    transport    The directed movement of substances (such as macromolecules, small molecules, ions) or cellular components (such as complexes and organelles) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter, pore or motor protein.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    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.
