Protein attributes
| Sequence length | 1151 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Plays a regulatory role in calcium-dependent exocytosis and neurotransmitter release. Inhibits membrane fusion between transport vesicles and the plasma membrane. May modulate the assembly of trans-SNARE complexes between transport vesicles and the plasma membrane. Inhibits translocation of GLUT4 from intracellular vesicles to the plasma membrane. Competes with STXBP1 for STX1 binding By similarity. |
| Subunit structure | Interacts with STX1A and STX1B via its v-SNARE homology domain. Part of a complex that contains STX1, STXBP5, SNAP25 and SYT1. Part of a complex that contains STXBP5, STX4A and SNAP23 By similarity. |
| Subcellular location | Cytoplasm By similarity. Cell membrane; Peripheral membrane protein By similarity. Cytoplasmic vesicle membrane; Peripheral membrane protein By similarity. Cytoplasmic vesicle › secretory vesicle › synaptic vesicle By similarity. Cell junction › synapse By similarity. Note: Cytoplasmic, and associated with vesicular membranes and the plasma membrane. Detected at synapses and on synaptic vesicles By similarity. |
| Sequence similarities | Belongs to the WD repeat L(2)GL family. Contains 1 v-SNARE coiled-coil homology domain. Contains 14 WD repeats. |
| Sequence caution | The sequence BAC03475.1 differs from that shown. Reason: Erroneous initiation. |
Ontologies
Alternative products
| This entry describes 3 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform 1 (identifier: Q5T5C0-1) This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry. | ||||||
| Isoform 2 (identifier: Q5T5C0-2) The sequence of this isoform differs from the canonical sequence as follows: 716-751: Missing. | ||||||
| Isoform 3 (identifier: Q5T5C0-3) The sequence of this isoform differs from the canonical sequence as follows: 716-768: Missing. |
