Descriptions
Small GTPases couple their GDP/GTP structural cycle to cytosol/membrane alternation to function as versatile molecular switches in the cell. Membrane localization of their active, GTP-bound form is pivotal to their ability to propagate information, and this requires their post-translational modification by lipids.<br>Arf GTPases are modified by a myristate attached to their N-terminus, which is shielded by intramolecular interactions in their inactive state. The myristoylated N-terminus of Arf is autoinhibitory in solution and is displaced by membranes, priming Arf GTPases for activation by their GEFs. Replacement of the N-terminal myristate by a 6xHis-tag preserves autoinhibition, representing that membranes unlock the N-terminal region to facilitate subsequent activation.

12 GO annotations of cellular component
| Name | Definition |
|---|---|
| cell leading edge | The area of a motile cell closest to the direction of movement. |
| cytosol | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. |
| endomembrane system | A collection of membranous structures involved in transport within the cell. The main components of the endomembrane system are endoplasmic reticulum, Golgi bodies, vesicles, cell membrane and nuclear envelope. Members of the endomembrane system pass materials through each other or though the use of vesicles. |
| glutamatergic synapse | A synapse that uses glutamate as a neurotransmitter. |
| Golgi apparatus | A membrane-bound cytoplasmic organelle of the endomembrane system that further processes the core oligosaccharides (e.g. N-glycans) added to proteins in the endoplasmic reticulum and packages them into membrane-bound vesicles. The Golgi apparatus operates at the intersection of the secretory, lysosomal, and endocytic pathways. |
| Golgi membrane | The lipid bilayer surrounding any of the compartments of the Golgi apparatus. |
| late endosome | A prelysosomal endocytic organelle differentiated from early endosomes by lower lumenal pH and different protein composition. Late endosomes are more spherical than early endosomes and are mostly juxtanuclear, being concentrated near the microtubule organizing center. |
| neuron projection | A prolongation or process extending from a nerve cell, e.g. an axon or dendrite. |
| plasma membrane | The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. |
| postsynaptic density | An electron dense network of proteins within and adjacent to the postsynaptic membrane of an asymmetric, neuron-neuron synapse. Its major components include neurotransmitter receptors and the proteins that spatially and functionally organize them such as anchoring and scaffolding molecules, signaling enzymes and cytoskeletal components. |
| protein-containing complex | A stable assembly of two or more macromolecules, i.e. proteins, nucleic acids, carbohydrates or lipids, in which at least one component is a protein and the constituent parts function together. |
| sarcomere | The repeating unit of a myofibril in a muscle cell, composed of an array of overlapping thick and thin filaments between two adjacent Z discs. |

24 GO annotations of biological process
| Name | Definition |
|---|---|
| actin filament organization | A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of cytoskeletal structures comprising actin filaments. Includes processes that control the spatial distribution of actin filaments, such as organizing filaments into meshworks, bundles, or other structures, as by cross-linking. |
| cellular response to virus | Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus from a virus. |
| dendritic spine organization | A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a dendritic spine. A dendritic spine is a specialized protrusion from a neuronal dendrite and is involved in synaptic transmission. |
| Golgi to transport vesicle transport | The directed movement of proteins from the Golgi to a transport vesicle. Continuously secreted proteins are sorted into transport vesicles that fuse with the plasma membrane, releasing their contents by exocytosis. |
| intracellular copper ion homeostasis | A homeostatic process involved in the maintenance of a steady state level of copper ions within a cell. |
| intracellular protein transport | The directed movement of proteins in a cell, including the movement of proteins between specific compartments or structures within a cell, such as organelles of a eukaryotic cell. |
| long-term synaptic depression | A process that modulates synaptic plasticity such that synapses are changed resulting in the decrease in the rate, or frequency of synaptic transmission at the synapse. |
| lysosomal membrane organization | A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a lysosomal membrane. A lysosomal membrane is the lipid bilayer surrounding the lysosome and separating its contents from the cell cytoplasm. |
| mitotic cleavage furrow ingression | Advancement of the mitotic cleavage furrow from the outside of the cell inward towards the center of the cell. The cleavage furrow acts as a 'purse string' which draws tight to separate daughter cells during mitotic cytokinesis and partition the cytoplasm between the two daughter cells. The furrow ingresses until a cytoplasmic bridge is formed. |
| positive regulation of calcium ion-dependent exocytosis | Any process that activates or increases the frequency, rate or extent of calcium ion-dependent exocytosis. |
| positive regulation of dendritic spine development | Any process that increases the rate, frequency, or extent of dendritic spine development, the process whose specific outcome is the progression of the dendritic spine over time, from its formation to the mature structure. |
| positive regulation of endocytosis | Any process that activates or increases the frequency, rate or extent of endocytosis. |
| positive regulation of ER to Golgi vesicle-mediated transport | Any process that activates or increases the frequency, rate or extent of ER to Golgi vesicle-mediated transport. |
| positive regulation of late endosome to lysosome transport | Any process that activates or increases the frequency, rate or extent of late endosome to lysosome transport. |
| positive regulation of protein secretion | Any process that activates or increases the frequency, rate or extent of the controlled release of a protein from a cell. |
| positive regulation of sodium ion transmembrane transport | Any process that activates or increases the frequency, rate or extent of sodium ion transmembrane transport. |

| regulation of Arp2/3 complex-mediated actin nucleation | Any process that modulates the frequency, rate or extent of actin nucleation mediated by the Arp2/3 complex and interacting proteins. |
| regulation of phospholipid metabolic process | Any process that modulates the frequency, rate or extent of phospholipid metabolic process. |
| regulation of receptor internalization | Any process that modulates the frequency, rate or extent of receptor internalization. |
| synaptic vesicle budding | Evagination of a membrane to form a synaptic vesicle. |
| very-low-density lipoprotein particle assembly | The non-covalent aggregation and arrangement of proteins and lipids in the liver to form a very-low-density lipoprotein particle. |
| vesicle-mediated transport | A cellular transport process in which transported substances are moved in membrane-bounded vesicles; transported substances are enclosed in the vesicle lumen or located in the vesicle membrane. The process begins with a step that directs a substance to the forming vesicle, and includes vesicle budding and coating. Vesicles are then targeted to, and fuse with, an acceptor membrane. |
