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.

8 GO annotations of cellular component
| Name | Definition |
|---|---|
| cytoplasm | The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| cytosol | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. |
| dendritic spine | A small, membranous protrusion from a dendrite that forms a postsynaptic compartment, typically receiving input from a single presynapse. They function as partially isolated biochemical and an electrical compartments. Spine morphology is variable:they can be thin, stubby, mushroom, or branched, with a continuum of intermediate morphologies. They typically terminate in a bulb shape, linked to the dendritic shaft by a restriction. Spine remodeling is though to be involved in synaptic plasticity. |
| 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. |
| plasma membrane | The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. |
| ruffle membrane | The portion of the plasma membrane surrounding a ruffle. |
5 GO annotations of molecular function

| epidermal growth factor receptor binding | Binding to an epidermal growth factor receptor. |
| GTP binding | Binding to GTP, guanosine triphosphate. |
| GTPase activity | Catalysis of the reaction |

17 GO annotations of biological process
| Name | Definition |
|---|---|
| apical protein localization | Any process in which a protein is transported to, or maintained in, apical regions of the cell. |
| cell migration | The controlled self-propelled movement of a cell from one site to a destination guided by molecular cues. |
| dendritic spine development | The process whose specific outcome is the progression of the dendritic spine over time, from its formation to the mature structure. A dendritic spine is a protrusion from a dendrite and a specialized subcellular compartment involved in synaptic transmission. |
| epidermal growth factor receptor signaling pathway | The series of molecular signals initiated by binding of a ligand to the tyrosine kinase receptor EGFR (ERBB1) on the surface of a cell. The pathway ends with regulation of a downstream cellular process, e.g. transcription. |
| establishment or maintenance of epithelial cell apical/basal polarity | Any cellular process that results in the specification, formation or maintenance of the apicobasal polarity of an epithelial 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. |
| learning | Any process in an organism in which a relatively long-lasting adaptive behavioral change occurs as the result of experience. |
| negative regulation of apoptotic process | Any process that stops, prevents, or reduces the frequency, rate or extent of cell death by apoptotic process. |
| positive regulation of transcription by RNA polymerase II | Any process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter. |
| protein localization to cilium | A process in which a protein is transported to, or maintained in, a location within a cilium. |
| regulation of cilium assembly | Any process that modulates the frequency, rate or extent of cilium assembly. |
| regulation of postsynapse organization | Any process that modulates the physical form of a postsynapse. |
| regulation of reactive oxygen species metabolic process | Any process that modulates the frequency, rate or extent of reactive oxygen species metabolic process. |
| regulation of synapse organization | Any process that modulates the physical form of a synapse, the junction between a neuron and a target (neuron, muscle, or secretory cell). |
| response to axon injury | Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an axon injury stimulus. |
| retrograde vesicle-mediated transport, Golgi to endoplasmic reticulum | The directed movement of substances from the Golgi back to the endoplasmic reticulum, mediated by vesicles bearing specific protein coats such as COPI or COG. |
| 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. |
