| molecular function |

| | GO:0005092 | | GDP-dissociation inhibitor activity | | Prevents the dissociation of GDP from a GTPase, thereby preventing GTP from binding. |
| | GO:0005096 | | GTPase activator activity | | Binds to and increases the activity of a GTPase, an enzyme that catalyzes the hydrolysis of GTP. |
| | GO:0005093 | | Rab GDP-dissociation inhibitor activity | | Prevents the dissociation of GDP from the small GTPase Rab, thereby preventing GTP from binding. |
| | GO:0016491 | | oxidoreductase activity | | Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced. |

| | GO:0032482 | | Rab protein signal transduction | | A series of molecular signals within the cell that are mediated by a member of the Rab family of proteins switching to a GTP-bound active state. |
| | GO:0050771 | | negative regulation of axonogenesis | | Any process that stops, prevents, or reduces the frequency, rate or extent of axonogenesis. |
| | GO:0090315 | | negative regulation of protein targeting to membrane | | Any process that decreases the frequency, rate or extent of the process of directing proteins towards a membrane, usually using signals contained within the protein. |
| | GO:0055114 | | oxidation-reduction process | | A metabolic process that results in the removal or addition of one or more electrons to or from a substance, with or without the concomitant removal or addition of a proton or protons. |
| | GO:0043547 | | positive regulation of GTPase activity | | Any process that activates or increases the activity of a GTPase. |
| | 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:0050790 | | regulation of catalytic activity | | Any process that modulates the activity of an enzyme. |
| | GO:0007264 | | small GTPase mediated signal transduction | | Any series of molecular signals in which a small monomeric GTPase relays one or more of the signals. |

| | GO:0005794 | | Golgi apparatus | | A compound membranous cytoplasmic organelle of eukaryotic cells, consisting of flattened, ribosome-free vesicles arranged in a more or less regular stack. The Golgi apparatus differs from the endoplasmic reticulum in often having slightly thicker membranes, appearing in sections as a characteristic shallow semicircle so that the convex side (cis or entry face) abuts the endoplasmic reticulum, secretory vesicles emerging from the concave side (trans or exit face). In vertebrate cells there is usually one such organelle, while in invertebrates and plants, where they are known usually as dictyosomes, there may be several scattered in the cytoplasm. The Golgi apparatus processes proteins produced on the ribosomes of the rough endoplasmic reticulum; such processing includes modification of the core oligosaccharides of glycoproteins, and the sorting and packaging of proteins for transport to a variety of cellular locations. Three different regions of the Golgi are now recognized both in terms of structure and function: cis, in the vicinity of the cis face, trans, in the vicinity of the trans face, and medial, lying between the cis and trans regions. |
| | GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| | GO:0005829 | | cytosol | | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. |
| | GO:0030496 | | midbody | | A thin cytoplasmic bridge formed between daughter cells at the end of cytokinesis. The midbody forms where the contractile ring constricts, and may persist for some time before finally breaking to complete cytokinesis. |
| | GO:0043209 | | myelin sheath | | An electrically insulating fatty layer that surrounds the axons of many neurons. It is an outgrowth of glial cells: Schwann cells supply the myelin for peripheral neurons while oligodendrocytes supply it to those of the central nervous system. |
