The exact function of MAP2 is unknown but MAPs may stabilize the microtubules against depolymerization. They also seem to have a stiffening effect on microtubules.
基因名
Map2
蛋白名
Microtubule-associated protein 2
亚细胞定位
Cytoplasm, cytoskeleton (Probable).
翻译后修饰
Phosphorylated at serine residues in K-X-G-S motifs by MAP/microtubule affinity-regulating kinase (MARK1 or MARK2), causing detachment from microtubules, and their disassembly (By similarity). MAP2A/c is phosphorylated. Isoform MAP2c is phosphorylated by FYN at Tyr-67.
相似性
Contains 3 Tau/MAP repeats.
