General description

The microtubule-associated protein 2 (MAP-2) is an abundant neuronal cytoskeletal protein that binds to tubulin, stabilizes microtubules (Herzog and Weber, 1978), and is an excellent marker for neurons. MAP-2 is essential for the development and maintenance of neuronal morphology (Matus, 1991). Three primary isoforms of MAP-2, the high molecular weight MAP2a and MAP2b, and the low molecular weight MAP2c (resulting from alternate splicing of the MAP2 gene), have been identified in neurours. (Chung et al., 1996). The low molecular weight isoform, MAP2c, is expressed in developing brain and is down-regulated during brain maturation, whereas the high molecular weight MAP2b is expressed in both developing and adult brain. The MAP2a appears only after brain maturation (Tucker, 1990). All these forms bind to microtubules through a domain near the carboxyl terminus that contains either three or four similar repeats of a 31-amino-acid motif (Lewis et al., 1988). MAP-2 together with MAP-4 and tau proteins belong to the family of thermostable proteins associated with microtubules.
