Descriptions
NSF is a member of the type II AAA+ (ATPase associated with various cellular activities) family. It plays a critical role in intracellular membrane trafficking by disassembling soluble NSF attachment protein receptor (SNARE) complexes. Mutations within the N-D1 linker region cause significant defects in the disassembly of the SNARE complex and the SNARE/α-SNAP complex binding activity. The middle region mutants of the NSF N-D1 linker have also increased basal ATPase activity.

4 GO annotations of cellular component
| Name | Definition |
|---|---|
| dendritic shaft | Cylindric portion of the dendrite, directly stemming from the perikaryon, and carrying the dendritic spines. |
| Golgi stack | The set of thin, flattened membrane-bounded compartments, called cisternae, that form the central portion of the Golgi complex. The stack usually comprises cis, medial, and trans cisternae; the cis- and trans-Golgi networks are not considered part of the stack. |
| 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. |
15 GO annotations of molecular function
| Name | Definition |
|---|---|
| ATP binding | Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator. |
| ATP hydrolysis activity | Catalysis of the reaction: ATP + H2O = ADP + H+ phosphate. ATP hydrolysis is used in some reactions as an energy source, for example to catalyze a reaction or drive transport against a concentration gradient. |
| ATP-dependent protein binding | Binding to a protein or protein complex using energy from ATP hydrolysis. |
| D1 dopamine receptor binding | Binding to a D1 dopamine receptor. |
| ionotropic glutamate receptor binding | Binding to an ionotropic glutamate receptor. Ionotropic glutamate receptors bind glutamate and exert an effect through the regulation of ion channels. |
| metal ion binding | Binding to a metal ion. |
| PDZ domain binding | Binding to a PDZ domain of a protein, a domain found in diverse signaling proteins. |
| protein C-terminus binding | Binding to a protein C-terminus, the end of a peptide chain at which the 1-carboxyl function of a constituent amino acid is not attached in peptide linkage to another amino-acid residue. |
| protein disaggregase activity | An ATP-dependent molecular chaperone activity that mediates the solubilization of ordered protein aggregates. |
| protein kinase binding | Binding to a protein kinase, any enzyme that catalyzes the transfer of a phosphate group, usually from ATP, to a protein substrate. |
| protein-containing complex binding | Binding to a macromolecular complex. |
| small GTPase binding | Binding to a small monomeric GTPase. |
| SNARE binding | Binding to a SNARE (soluble N-ethylmaleimide-sensitive factor attached protein receptor) protein. |
| syntaxin binding | Binding to a syntaxin, a SNAP receptor involved in the docking of synaptic vesicles at the presynaptic zone of a synapse. |
| syntaxin-1 binding | Binding to a syntaxin-1 SNAP receptor. |
13 GO annotations of biological process
| Name | Definition |
|---|---|
| Golgi to plasma membrane protein transport | The directed movement of proteins from the Golgi to the plasma membrane in transport vesicles that move from the trans-Golgi network to the plasma membrane. |
| Golgi vesicle docking | The initial attachment of a Golgi transport vesicle membrane to a target membrane, mediated by proteins protruding from the membrane of the Golgi vesicle and the target membrane. |
| intra-Golgi vesicle-mediated transport | The directed movement of substances within the Golgi, mediated by small transport vesicles. These either fuse with the cis-Golgi or with each other to form the membrane stacks known as the cis-Golgi reticulum (network). |
| 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. |
| positive regulation of protein catabolic process | Any process that activates or increases the frequency, rate or extent of the chemical reactions and pathways resulting in the breakdown of a protein by the destruction of the native, active configuration, with or without the hydrolysis of peptide bonds. |
| positive regulation of receptor recycling | Any process that activates or increases the frequency, rate or extent of receptor recycling. |
| potassium ion transport | The directed movement of potassium ions (K+) into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. |
| 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. |
| protein-containing complex disassembly | The disaggregation of a protein-containing macromolecular complex into its constituent components. |
| regulation of exocytosis | Any process that modulates the frequency, rate or extent of exocytosis. |
| regulation of receptor internalization | Any process that modulates the frequency, rate or extent of receptor internalization. |
| SNARE complex disassembly | The disaggregation of the SNARE protein complex into its constituent components. The SNARE complex is a protein complex involved in membrane fusion; a stable ternary complex consisting of a four-helix bundle, usually formed from one R-SNARE and three Q-SNAREs with an ionic layer sandwiched between hydrophobic layers. |
| 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. |
