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. NSF is a ring-shaped homohexameric protein, with each protomer consisting of three domains: an N-terminal domain (N domain) and two highly conserved AAA+ domains (D1 and D2 domains). 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 and C-terminal region mutants of the NSF N-D1 linker have also increased basal ATPase activity.

1 GO annotations of cellular component

Name Definition
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

3 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.
metal ion binding Binding to a metal ion.

2 GO annotations of biological process

Name Definition
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.
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.
