Protein attributes

Sequence length	116 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Involved in the targeting and/or fusion of transport vesicles to their target membrane By similarity.
Subunit structure	Part of the SNARE core complex containing SNAP25, VAMP2 and STX1A. This complex binds to CPLX1. Interacts with VAPA and VAPB By similarity.
Subcellular location	Cytoplasmic vesicle › secretory vesicle › synaptic vesicle membrane; Single-pass type IV membrane protein. Cell junction › synapse › synaptosome. Note: Neuronal synaptic vesicles.
Tissue specificity	Nervous system specific. A higher level expression is seen in the brain as compared to the spinal cord. Ref.1
Sequence similarities	Belongs to the synaptobrevin family. Contains 1 v-SNARE coiled-coil homology domain.
