[Abstract] Activity-dependent local mRNA translation endows synapses to remodel their structure and function (Bramham and Wells, 2007). This process is tightly controlled by the state of phosphorylation of several components of the translational machinery including initiation factors and ribosomal proteins (Buffington et al., 2014). The present protocol describes a method to prepare striatal synaptoneurosomes, from adult mice, containing both pre- and postsynaptic elements in which the level of synaptic phospho-proteins can be quantified (Biever et al., 2015).
[摘要] 活动依赖的局部mRNA翻译赋予突触重塑其结构和功能（Bramham和Wells，2007）。 该过程由包括起始因子和核糖体蛋白在内的翻译机理的几个组分的磷酸化状态来严格控制（Buffington等，2014）。 本方案描述了一种从成年小鼠制备纹状体synaptoneurosomes的方法，其含有可以量化突触磷酸蛋白水平的突触前和突触后元件（Biever等，2015）。

[Abstract] The mitogen activated protein kinase cascade is a highly conserved signal pathway in plants. The exogenous chemicals, like hormones, can trigger a series of signalling cascades, including MAPK pathway, to modulate the plant physiology. Upon activation, some MAPKs are phosphorylated. It is important to develop methods that can detect changes in the phosphorylation status of MAPKs in plants when they come in contact with external chemicals. This method describes the exogenous treatment of Arabidopsis protoplasts with Kinetin and subsequent detection of the activated MAPKs. This method ...
[摘要] 丝裂原活化蛋白激酶级联是植物中高度保守的信号通路。 外源化学物质，如激素，可以触发一系列信号级联，包括MAPK途径，以调节植物生理。 在激活时，一些MAPK被磷酸化。 开发能够检测植物中MAPK在与外部化学品接触时磷酸化状态的变化的方法是重要的。 该方法描述了用激动素对随后检测激活的MAPK的拟南芥原生质体的外源处理。 该方法可用于研究外源施加的化合物对拟南芥中MAPK信号级联的影响。
