      Alternate Names
      • Microtubule Associated Protein
      • MAP2A and 2B
      Background InformationMAP-2 (microtubule associated protein-2) is one of several high molecular weight proteins that play an important role in brain neuron microtubule assembly. In addition to its association with microtubules, MAP-2 associates with neurofilaments and actin filaments suggesting that it may guide interaction among microtubules, other cytoskeletal elements, and cytoplasmic organelles. MAP-2 is a stringent marker for neurons. In addition, MAP-2 displays intracellular specificity. In the central nervous system, MAP-2 is confined to neuronal cell bodies and dendrites. There are exceptions, however, where some axons stain positive for small amounts of MAP-2. MAP-2 is uniformly distributed throughout the cell when first expressed in cultured neurons but becomes selectively localized as dendritic development proceeds. (Caceres, 1986; Dotti, 1987).

      Key Applications
      • Immunohistochemistry
      • Western Blotting
      Application NotesWestern Blot:
      60 ng/mL. In SDS-PAGE, MAP-2 from adult rat migrates as a closely associated doublet having a molecular weight of approximately 280-300 kD representing the MAP-2A and -2B isoforms but not the 70 kDa MAP-2C isoform. However, early in brain development (postnatal day 10 in rats), MAP-2 migrates as a single band that is identical to the lower molecular weight band of the adult MAP-2 doublet (MAP-2b). Later in development (postnatal days 17-18), the mobility of MAP-2 changes to the adult doublet form. (In the spinal cord, conversion to the adult form occurs earlier). Users should run 4%-20% SDS-PAGE gradient gels.

      5 µg/mL (4% PFA fixed frozen sections).

      5 µg/mL of a previous lot was used. Anti-MAP-2 can be used to stain tissue (brain or spinal cord) fixed with paraformaldehyde.

      Optimal working concentrations must be determined by the end user.

      Entrez Gene Number
      Entrez Gene SummaryThis gene encodes a protein that belongs to the microtubule-associated protein family. The proteins of this family are thought to be involved in microtubule assembly, which is an essential step in neurogenesis. The products of similar genes in rat and mouse are neuron-specific cytoskeletal proteins that are enriched in dentrites, implicating a role in determining and stabilizing dentritic shape during neuron development. A number of alternatively spliced variants encoding distinct isforms have been described.

      UniProt Number
      UniProt SummaryFUNCTION: SwissProt: P11137 # The exact function of MAP2 is unknown but MAPs may stabilize the microtubules against depolymerization. They also seem to have a stiffening effect on microtubules.
      SIZE: 1827 amino acids; 199539 Da
      PTM: MAP2A/c is phosphorylated. Phosphorylated upon DNA damage, probably by ATM or ATR.
      SIMILARITY: SwissProt: P11137 ## Contains 3 Tau/MAP repeats.
