Anti-extended synaptotagmin protein 2 antibodies are used in antigen-specific immunodetection in biological samples. The target extended synaptotagmin protein 2 is a known alias name of the protein extended synaptotagmin 2, encoded by the ESYT2 gene in humans. This 921-amino acid residue protein is known to be involved in endocytosis and the metabolism of lipids, among other biological processes. It is localized to the ER and cell membrane of the cell. In terms of tissue expression, it is reported to be widely expressed with high level in cerebellum.
