      Background InformationMAP-2 (microtubule associated protein-2) is on of several high molecular weight proteins that play an important role in brain 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 (Binder, 1984).

      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 (Caceres, 1984; Binder, 1986). 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 NotesImmunohistochemistry:
      1:50-1:200. AP20 stains dendrites and neuron cells bodies but not neuronal processes and axons. A previous lot of this antibody was used in immunohistochemistry.

      Western blot:
      SDS-PAGE Profiles: In SDS-PAGE MAP-2 from adult rat migrates as a closely associated doublet having a molecular weight of approximately 300 kD. 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).

      Western blot: A 1:500 dilution was used in a previous lot.

      Optimal working dilutions must be determined by 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.
