Anti-discs large homolog associated protein 1 antibodies are used in antigen-specific immunodetection in biological samples. The target discs large homolog associated protein 1 is a known alias name of the protein DLG associated protein 1, encoded by the DLGAP1 gene in humans. This 977-amino acid residue protein is known to be a part of the postsynaptic scaffold in neuronal cells. It is localized to the cell membrane of the cell and features ubiquitinated post-translational modifications. In terms of tissue expression, it is reported to be expressed in the brain.
