Anti-STX3

The gene is a member of the syntaxin family. The encoded protein is targeted to the apical membrane of epithelial cells where it forms clusters and is important in establishing and maintaining polarity necessary for protein trafficking involving vesicle fusion and exocytosis. Alternative splicing results in multiple transcript variants. Protein function: Potentially involved in docking of synaptic vesicles at presynaptic active zones. [The UniProt Consortium]
