      • SAP90/PSD-95-associated protein 1
      • disks large-associated protein 1

      Background InformationSAPAP1 is a member of the SAPAP family of proteins and is thought to be instrumental in the postsynaptic scaffold of neurons. SAPAP1 may function to assemble various other proteins at synapses. These functional proteins include scaffolding proteins, signaling proteins and cytoskeletal proteins. SAPAP1 is primarily found in the brain and more specifically in the cell body zones.
      Product Information
      • Rat brain membrane tissue lysate
      PresentationPurified mouse monoclonal IgG2bκ in buffer containing 0.1 M Tris-Glycine (pH 7.4), 150 mM NaCl with 0.05% sodium azide.
      ApplicationThis Anti-pan-SAPAP Antibody, clone N127/31 is validated for use in IH, WB for the detection of pan-SAPAP.
      Key Applications
      • Immunohistochemistry
      • Western Blotting
      Application NotesImmunohistochemistry Analysis: 1:400 dilution from a previous lot detected SAPAP in rat schwan cells (putamen area) and rat dopaminergic neurons.

      Immunofluorescence Analysis: A previous lot of this antibody was used by an independent laboratory in cultured rat hippocampal pyramidal cells and interneurons. (Courtesy of Dieter Edbauer and Morgan Sheng, Picower Institute, MIT.)

      UniProt SummaryFUNCTION: Part of the postsynaptic scaffold in neuronal cells.

      SUBUNIT STRUCTURE: Interacts with guanylate kinase-like domain of DLG1, DLG2, DLG3, DLG4 and AIP1. Interacts with the PDZ domain of SHANK1, SHANK2 and SHANK3. Found in a complex with DLG4 and SHANK1, SHANK2 or SHANK3. Found in a complex with DLG4 and BEGAIN. Interacts with DYL2 and LRFN1.

      SUBCELLULAR LOCATION: Cell membrane; Peripheral membrane protein. Cell junction › synapse › postsynaptic cell membrane › postsynaptic density. Cell junction › synapse. Note: Found in postsynaptic density of neuronal cells.

      TISSUE SPECIFICTY: Expressed in brain and testis.

      DEVELOPMENTAL STAGE: Highest level of isoform 1 in the brain of newborn rats. Increasing levels of isoforms 2, 3, 4, and 5 in the brain of newborn rats from birth to 6 weeks of postnatal development. Increasing but low level of isoform 6 is expressed in the brain from 2 to 6 weeks of postnatal development.

      SEQUENCE SIMILARITIES: Belongs to the SAPAP family.
      Molecular WeightIsoforms between ~90-120 kDa observed. Other isoforms may be observed in some lysates.
