神经元有自己的调节RNA的系统。几个多基因家族编码RNA结合蛋白(RNABPs),这些蛋白在神经元中唯一表达,包括众所周知的神经元特异性标记物ELAV和NeuN,以及疾病抗原NOVA。近年来出现了新的技术来评估这些蛋白质在体内的功能,这些答案正在深入了解神经元如何以及为什么会以特殊的方式调节RNA——增加细胞的复杂性,在空间上定位mRNA,并在突触刺激下调节其表达。这种受限制的神经元蛋白的功能很可能得到更广泛表达的RNABPs的补充,这些RNABPs本身可能在神经元中具有专门的功能,包括Argonaute/miRNAs。在这里,我们回顾了这些RNABPs的已知情况,并探讨了神经元RNA调节系统的潜在生物学和神经学意义。
Neurons have their own systems for regulating RNA. Several multigene families encode RNA binding proteins (RNABPs) that are uniquely expressed in neurons, including the well-known neuron-specific markers ELAV and NeuN, and the disease antigen NOVA. New technologies have emerged in recent years to assess the function of these proteins in vivo, and the answers are yielding insights into how and why neurons may regulate RNA in special ways—to increase cellular complexity, to spatially localize mRNA, and to regulate their expression in response to synaptic stimuli. The functions of such restricted neuronal proteins is likely to be complimented by more widely expressed RNABPs that may themselves have developed specialized functions in neurons, including Argonaute/miRNAs. Here we review what is known about such RNABPs, and explore the potential biologic and neurologic significance of neuronal RNA regulatory systems.
