GO
GO:0015031 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:0017038 The targeting and directed movement of proteins into a cell or organelle. Not all import involves an initial targeting event. GO:0042597 The region between the inner (cytoplasmic) and outer membrane (Gram-negative Bacteria) or cytoplasmic membrane and cell wall (Fungi and Gram-positive Bacteria). GO:0051301 The process resulting in division and partitioning of components of a cell to form more cells; may or may not be accompanied by the physical separation of a cell into distinct, individually membrane-bounded daughter cells.
