ID:SNP23_HUMAN DESCRIPTION: RecName: Full=Synaptosomal-associated protein 23; Short=SNAP-23; AltName: Full=Vesicle-membrane fusion protein SNAP-23; FUNCTION: Essential component of the high affinity receptor for the general membrane fusion machinery and an important regulator of transport vesicle docking and fusion. SUBUNIT: Binds simultaneously to SNAPIN and SYN4. Found in a complex with VAMP8 and STX4 in pancreas. Interacts with STX1A and STX12 (By similarity). Binds tightly to multiple syntaxins and synaptobrevins/VAMPs. Found in a complex with VAMP8 and STX1A. INTERACTION: P54920:NAPA; NbExp=2; IntAct=EBI-745000, EBI-749652; SUBCELLULAR LOCATION: Cell membrane; Peripheral membrane protein. Cell membrane; Lipid-anchor. Cell junction, synapse, synaptosome. Note=Mainly localized to the plasma membrane. TISSUE SPECIFICITY: Ubiquitous. Highest levels where found in placenta. SIMILARITY: Belongs to the SNAP-25 family. SIMILARITY: Contains 2 t-SNARE coiled-coil homology domains.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
