Biological Significance: ExpandCollapse

Microtubules are 25nm diameter protein rods found in most kinds of eukaryotic cells. They are polymerized from a dimeric subunit made of one a subunit and one b tubulin subunit. Microtubules are associated with a family of proteins called microtubule associated proteins (MAPs), which includes the protein t (tau) and a group of proteins referred to as MAP1, MAP2, MAP3, MAP4 and MAP5 (Kindler & Gardner 1994). MAP2 is made up of two ~280 kDa apparent molecular weight bands referred to as MAP2a and MAP2b. A third lower molecular weight form, usually called MAP2c, corresponds to a pair of protein bands running at ~70 kDa on SDS-PAGE gels. All these MAP2 forms are derived from a single gene by alternate transcription, and all share a C-terminal sequence which includes either three or four microtubule binding peptide sequences, which are very similar to those found in the related microtubule binding protein t (tau). MAP2 isoforms are expressed only in neuronal cells and specifically in the perikarya and dendrites of these cells. MAP2 has been recently shown to be the specific receptor for the neurosteroid pregnenolone (Fontaine-Lenore V. et al., 2006).

Immunofluorescent image of primary mouse neurons specifically labelling MAP2 (catalog #1099-MAP2, 1:1000, red). The blue nuclear stain is Hoechst. The primary mouse neurons were initially fixed with 4% PFA for 30 minutes, and then washed with PBS. The cells were blocked with 3% bovine serum albumin in PBS for 90 minutes before incubating with primary antibody overnight at 4C. The anti-MAP2 antibody was diluted in the blocking buffer. An Alexa-568 anti-goat secondary antibody was used at 1:500. The tissue sections were washed with PBS between each of the blocking and incubation steps. The image was kindly provided by Noah Johnson, University of Colorado, Anschutz Medical Campus.
