SYT8 polyclonal antibody

Synaptotagmins are a large gene family of synaptic vesicle type III integral membrane proteins that function as regulators of both exocytosis and endocytosis and are involved in neurotransmitter secretion from small secretory vesicles. The Synaptotagmin family of proteins share a common domain structure that consists of a transmembrane domain and a cytoplasmic region composed of two C2 domains. Synaptotagmin VIII, also known as SYT8, is a 401 amino acid single-pass type III membrane protein belonging to the Synaptotagmin family. Containing two C2 domains, Synaptotagmin VIII exists as a homodimer or homooligomer. Synaptotagmin VIII exists as two alternatively spliced isoforms, isoform 1 and isoform 4. Synaptotagmin VIII isoform 4 is thought to participate in the trafficking and exocytosis of secretory vesicles in non-neuronal tissues.
