    GO:0051262    protein tetramerization    The formation of a protein tetramer, a macromolecular structure consisting of four noncovalently associated identical or nonidentical subunits.
    GO:0015031    protein transport    The directed movement of proteins into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
    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
