Microtubule-associated protein 2 (MAP2) is a neurosteroid receptor.
The neurosteroid pregnenolone (PREG) and its chemically synthesized analog 3beta-methoxypregnenolone (MePREG) bind to microtubule-associated protein 2 (MAP2) and stimulate the polymerization of microtubules. PREG, MePREG, and progesterone (PROG; the physiological immediate metabolite of PREG) significantly enhance neurite outgrowth of nerve growth factor-pretreated PC12 cells. However, PROG, al...
متن کاملRegulated association of microtubule-associated protein 2 (MAP2) with Src and Grb2: evidence for MAP2 as a scaffolding protein.
Microtubule-associated protein 2 (MAP2) and tau, which is involved in Alzheimer's disease, are major cytoskeletal proteins in neurons. These proteins are involved in microtubule assembly and stability. To further characterize MAP2, we took a strategy of identifying potential MAP2 binding partners. The low molecular weight MAP2c protein has 11 PXXP motifs that are conserved across species, and t...
متن کاملThe phosphatidylinositol-binding site of microtubule-associated protein MAP2.
Recent evidence [Surridge and Burns, Biochemistry (1994) 33, 8051-8057] on the interaction of native and recombinant tau, recombinant MAP2c, and native MAP2 with vesicles prepared from phosphatidylinositol (PtdIns) and other phospholipids demonstrate that MAP2 differs from MAP2c and from tau in having a high-affinity PtdIns-binding site. The location of this site within the MAP2-specific insert...
متن کاملAn isoform of microtubule-associated protein 2 (MAP2) containing four repeats of the tubulin-binding motif.
Microtubule-associated protein 2 (MAP2) exists in both high- and low-molecular mass isoforms, each of which has a tubulin-binding domain consisting of 3 imperfect tandem repeats of 31 amino acids containing a more highly conserved 18 amino acid 'core' sequence. We describe here a novel form of low molecular mass MAP2 (MAP2c) that contains an additional 4th repeat of this tubulin-binding motif. ...
متن کاملPhosphorylation determines the binding of microtubule-associated protein 2 (MAP2) to microtubules in living cells
The influence of phosphorylation on the binding of microtubule-associated protein 2 (MAP2) to cellular microtubules was studied by microinjecting MAP2 in various phosphorylation states into rat-1 fibroblasts, which lack endogenous MAP2. Conventionally prepared brain MAP2, containing 10 mol of endogenous phosphate per mol (MAP2-P10), was completely bound to cellular microtubules within 2-3 min a...
