SNAP23
Essential component of the high affinity receptor for the general membrane fusion machinery and an important regulator of transport vesicle docking and fusion. Belongs to the SNAP-25 family. Ubiquitous. Highest levels where found in placenta. 2 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
