Most if not all vesicular membrane fusion events in eukaryotic cells are believed to be mediated by a conserved fusion machinery, the SNARE [soluble N-ethylmaleimide-sensitive factor (NSF) attachment protein (SNAP) receptors] machinery. The SNARE domain is thought to act as a protein-protein interaction module in the assembly of a SNARE protein complex. Length = 62

>PF05739 SNARE: SNARE domain; InterPro: IPR000727 The process of vesicular fusion with target membranes depends on a set of SNAREs (SNAP-Receptors), which are associated with the fusing membranes [, ]
Target SNAREs (t-SNAREs) are localised on the target membrane and belong to two different families, the syntaxin-like family and the SNAP-25 like family. One member of each family, together with a v-SNARE localised on the vesicular membrane, are required for fusion. The Syntaxins are type-I transmembrane proteins that contain several regions with coiled-coil propensity in their cytosolic part, the SNARE motif. SNAP-25 (IPR000928 from INTERPRO) is a protein consisting of two coiled-coil regions, which is associated with the membrane by lipid anchors. SNARE motifs assemble into parallel four helix bundles stabilised by the burial of these hydrophobic helix faces in the bundle core. Monomeric SNARE motifs are disordered so this assembly reaction is accompanied by a dramatic increase in alpha-helical secondary structure []. The parallel arrangement of SNARE motifs within complexes bring the transmembrane anchors, and the two membranes, into close proximity. Recently, it was shown that the two coiled-coil regions of SNAP-25 and one of the coiled-coil regions of the syntaxins are related []. This domain is found in both Syntaxin and SNAP-25 families as well as in other proteins.; GO: 0005515 protein binding; PDB: 1URQ_B 3RL0_R 1HVV_B 1SFC_B 1N7S_B 3IPD_B 3C98_B 3HD7_F 3RK2_B 1KIL_B ....

>PF09753 Use1: Membrane fusion protein Use1; InterPro: IPR019150 This entry represents a family of proteins, approximately 300 residues in length, involved in vesicle transport
They have a single C-terminal transmembrane domain and a SNARE [soluble NSF (N-ethylmaleimide-sensitive fusion protein) attachment protein receptor] domain of approximately 60 residues. The SNARE domains are essential for membrane fusion and are conserved from yeasts to humans. Use1 is one of the three protein subunits that make up the SNARE complex and it is specifically required for Golgi-endoplasmic reticulum retrograde transport [].
