突触前谷氨酸通过激活AMPA受体释放神经元膜去极化的兴奋性短波。根据其精确的大小和形状,通过AMPA受体的电流控制下游过程,如NMDA受体激活和动作电位产生。对AMPA受体结构和功能的十多年研究已经确定了AMPA受体上激动剂、拮抗剂和变构调节剂的结合位点以及各种AMPA受体亚型门控行为差异的关键残基。然而,最近的发现,AMPA受体伴随着在突触膜上的一个家庭的辅助亚基称为跨膜AMPA受体调节蛋白(TARP),揭示了神经元AMPA受体的动力学和药理学在许多方面不同的AMPA受体在异源系统中的经典研究所预测的。在这里,我们总结了最近的工作,并讨论了剩余的问题,有关的结构和功能的天然TARP-AMPA受体复合物。
Presynaptic glutamate release elicits brief waves of membrane depolarization in neurons by activating AMPA receptors. Depending on its precise size and shape, current through AMPA receptors gates downstream processes like NMDA receptor activation and action potential generation. Over a decade of research on AMPA receptor structure and function has identified binding sites on AMPA receptors for agonists, antagonists and allosteric modulators as well as key residues underlying differences in the gating behavior of various AMPA receptor subtypes. However, the recent discovery that AMPA receptors are accompanied in the synaptic membrane by a family of auxiliary subunits known as transmembrane AMPA receptor regulatory proteins (TARPs) has revealed that the kinetics and pharmacology of neuronal AMPA receptors differ in many respects from those predicted by classical studies of AMPA receptors in heterologous systems. Here, we summarize recent work and discuss remaining questions concerning the structure and function of native TARP–AMPA receptor complexes.
