Applications Key: W=Western Blotting,


Species predicted to react based on 100% sequence homology: Mouse,

Specificity / Sensitivity

Phospho-MAP2 (Thr1620/1623) Antibody detects transfected MAP2 (at a dilution of up to 1:20,000) only when phosphorylated at threonines 1620/1623. This antibody does not cross-react with phosphorylated tau.

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Thr1620/1623 of human MAP2. Antibodies are purified by protein A and peptide affinity chromatography.


Western Blotting

Western Blotting

Western blot analysis of extracts from COS cells, untransfected (lane 1), or MAP2C transfected (lanes 2,3), using Phospho-MAP2 (Thr1620/1623) Antibody (upper) or MAP2 Antibody #4542 (lower). In lane 3, the lysate was treated with lamda phosphatase to demonstrate phospho-specificity of the antibody. (Human MAP2C construct is a generous gift from Dr. B. Shafit-Zagardo, Dept. of Pathology, Albert Einstein College of Medicine, Bronx, NY.)

Microtubule-associated protein 2 (MAP2) is a neuronal phosphoprotein that regulates the structure and stability of microtubules, neuronal morphogenesis, cytoskeleton dynamics and organelle trafficking in axons and dendrites (1). Multiple MAP2 isoforms are expressed in neurons, including high molecular weight MAP2A and MAP2B (280 and 270 kDa), and low molecular weight MAP2C and MAP2D (70 and 75 kDa). Phosphorylation of MAP2 modulates its association with the cytoskeleton and is developmentally regulated. Serine 136, threonine 1620 and threonine 1623 of MAP2 are phosphorylated by GSK3 and p44/42 MAP kinases (2,3). Phosphorylation at threonine 1620/1623 by GSK3 inhibits MAP2 association with microtubules and microtubule stability (3).

微管相关蛋白2(MAP2)是一种神经元磷酸化蛋白,调节轴突和树突中微管的结构和稳定性,神经元的形态,细胞骨架动力学和细胞器的运输(1)。MAP2的多种亚型在神经元表达,其中包括超高分子量MAP2A和MAP2B(280和270 kDa),低分子量MAP2C和MAP2D(70和75 kDa)。微管相关蛋白的磷酸化调节其与细胞骨架的结合,并受到发育的调控。MAP2的丝氨酸136,苏氨酸1620和苏氨酸1623的磷酸化由GSK3和p44/42 MAP激酶完成(2,3)。GSK3对苏氨酸1620/1623的磷酸化抑制MAP2与微管蛋白结合,削弱微管稳定性(3)。
