神经丝由三个亚单位组成:神经丝轻链、中链和重链(核因子-L、核因子-M和核因子-H)。核因子-M和核因子-H的羧基末端结构域形成侧臂,从细丝伸出,而核因子-H的羧基末端结构域包含Lys-Ser-Pro基序的多个重复,其丝氨酸是磷酸化的靶。Lys-Ser-Pro重复序列上的磷酸化水平在细胞内的地形上是不同的;在细胞体和近端轴突中,侧臂基本上是非磷酸化的,而在轴突更远的区域,侧臂是高度磷酸化的。在这里,我们展示了应激激活蛋白激酶1b(SAPK1b),神经元中的一种主要的SAPK,将在体外和转基因细胞中磷酸化核因子-H侧臂。这些研究表明,SAPK1b针对核因子-H侧臂中的多个磷酸化位点。此外,我们还发现谷氨酸处理诱导了初级皮质神经元中SAPK1b的激活,并增加了细胞体中核因子-H的磷酸化。这表明谷氨酸至少在一定程度上通过激活应激激活的蛋白激酶导致核因子-H的磷酸化增加。
Neurofilaments comprise three subunit proteins; neurofilament light, middle and heavy chains (NF-L, NF-M and NF-H). The carboxy-terminal domains of NF-M and NF-H form side-arms that project from the filament and that of NF-H contains multiple repeats of the motif lys-ser-pro, the serines of which are targets for phosphorylation. The level of phosphorylation on the lys-ser-pro repeats varies topographically within the cell; in cell bodies and proximal axons, the side-arms are largely non-phosphorylated whereas in more distal regions of axons, the side-arms are heavily phosphorylated. Here we show that stress activated protein kinase 1b (SAPK1b), a major SAPK in neurones will phosphorylate NF-H side-arms both in vitro and in transfected cells. These studies suggest that SAPK1b targets multiple phosphorylation sites within NF-H side-arms. Additionally, we show that glutamate treatment induces activation of SAPK1b in primary cortical neurones and increased phosphorylation of NF-H in cell bodies. This suggests that glutamate causes increased NF-H phosphorylation at least in part by activation of stress activated protein kinases.
