Anti-DLG2 antibodies are used in the immunodetection of the protein discs large MAGUK scaffold protein 2. In humans, the canonical protein has a reported length of 870 amino acid residues and a mass of 97.6 kDa. Its subcellular localization is in the cell membrane. Up to 5 different isoforms have been reported for this protein. It is notably expressed in the rectum, hippocampus, cerebral cortex, and cerebellum. A member of the MAGUK protein family, DLG2 is known to be required for perception of chronic pain through NMDA receptor signaling. DLG2 is also used as a cellular marker for characterizing neuronal cells. Synonyms for this target antigen include PSD-93, PSD93, chapsyn-110, disks large homolog 2, channel-associated protein of synapse-110, and PPP1R58. DLG2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of DLG2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
