Anti-SLP2A antibodies enable researchers to detect and measure the SLP2A antigen in biological samples. This target is a reported synonym of the SYTL2 gene, which encodes synaptotagmin like 2. This protein is known to function in exocytosis and intracellular protein transport, among other biological roles. The human version of SLP2A has a canonical amino acid length of 934 residues and a protein mass of 104.9 kilodaltons, although 12 isoforms have been identified. It is reported to be localized in the cell membrane and cytoplasm of cells and notably expressed in many tissues, such as the adrenal gland and appendix. Other names for this target antigen include CHR11SYT, EXO4, and PPP1R151.
