Anti-sst2 antibodies enable researchers to detect and measure the sst2 antigen in biological samples. This target is a reported synonym of the SSTR2 gene, which encodes somatostatin receptor 2. This protein is known to function in brain development and the regulation of cell proliferation, among other biological roles. The human version of sst2 has a canonical amino acid length of 369 residues and a protein mass of 41.3 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cell membrane and cytoplasm of cells. sst2 is a member of the G-protein coupled receptor 1 protein family.
