This gene encodes a protein that belongs to the microtubule-associated protein family. The proteins of this family were originally isolated since they copurify with tubulin in polymerization experiments: tubulin in cell extracts can be made to polymerize to produce microtubules (MT) under the influence of heat and the addition of GTP, and the MT can then be collected by centrifugation. When this is done a series of microtubule associated proteins are collected alon… channing tatum feetWeb微管结合蛋白 2 (MAP2) 是一种神经元磷蛋白，可调节微管的结构和稳定性、神经元形态形成、细胞骨架动力学以及轴突和树突细胞中的细胞器转运 (1)。神经元中有多种 MAP2 同工型表达，包括高分子量 MAP2A 和 MAP2B（280 和 270 kda）和低分子量 MAP2C 和 MAP2D（70 和 75 kda）。 channing tatum dog moviesWeb23. mar 2024. · Syntax.
