molecular function
    GO:0015169    glycerol-3-phosphate transmembrane transporter activity    Enables the transfer of glycerol-3-phosphate from one side of the membrane to the other. Glycerol-3-phosphate is a phosphoric monoester of glycerol.
    GO:0015527    glycerol-phosphate:inorganic phosphate antiporter activity    Catalysis of the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: glycerol phosphate(out) + inorganic phosphate(in) = glycerol phosphate(in) + inorganic phosphate(out).
    GO:0015315    organophosphate:inorganic phosphate antiporter activity    Catalysis of the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: organophosphate(out) + inorganic phosphate(in) = organophosphate(in) + inorganic phosphate(out).
    GO:0005215    transporter activity    Enables the directed movement of substances (such as macromolecules, small molecules, ions) into, out of or within a cell, or between cells.
biological process
    GO:0006071    glycerol metabolic process    The chemical reactions and pathways involving glycerol, 1,2,3-propanetriol, a sweet, hygroscopic, viscous liquid, widely distributed in nature as a constituent of many lipids.
    GO:0015793    glycerol transport    The directed movement of glycerol into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. Glycerol is 1,2,3-propanetriol, a sweet, hygroscopic, viscous liquid, widely distributed in nature as a constituent of many lipids.
    GO:0015794    glycerol-3-phosphate transport    The directed movement of glycerol-3-phosphate into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. Glycerol-3-phosphate is a phosphoric monoester of glycerol.
    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: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:0016021    integral component of membrane    The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
    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.
