蛋白质翻译的空间调控是造成细胞功能和结构不对称的有效途径。最近的研究进一步加深了我们对单个细胞如何在空间上组织蛋白质合成的理解,通过应用创新技术来表征mRNA与其调节蛋白之间的关系,单mRNA运输动力学,取消mRNA在体内定位的生理效应以及内源性mRNA标记。新的成像技术的实施已经产生了mRNA定位的有价值的信息,例如,通过观察组织中的单个分子。mRNA在形态上不同的单细胞生物和神经元中的运动和定位模式揭示了mRNA定位的共同和特殊机制,转基因和生化技术补充了这一信息,揭示了mRNA错定位的生物学后果。
The spatial regulation of protein translation is an efficient way to create functional and structural asymmetries in cells. Recent research has furthered our understanding of how individual cells spatially organize protein synthesis, by applying innovative technology to characterize the relationship between mRNAs and their regulatory proteins, single-mRNA trafficking dynamics, physiological effects of abrogating mRNA localization in vivo and for endogenous mRNA labelling. The implementation of new imaging technologies has yielded valuable information on mRNA localization, for example, by observing single molecules in tissues. The emerging movements and localization patterns of mRNAs in morphologically distinct unicellular organisms and in neurons have illuminated shared and specialized mechanisms of mRNA localization, and this information is complemented by transgenic and biochemical techniques that reveal the biological consequences of mRNA mislocalization.
