Activated nuclear metabotropic glutamate receptor mGlu5 couples to nuclear Gq/11 proteins to generate inositol 1,4,5-trisphosphate-mediated nuclear Ca2+ release.
本文报道了激活的核代谢型谷氨酸受体5(mGlu5)如何偶联核Gq/11蛋白并产生肌醇1,4,5-三磷酸(IP3)介导的核内Ca2+释放。此前研究显示mGlu5可表达于异源细胞核膜或纹状体神经元内源核膜,并介导核Ca2+变化。作者采用药理学、光学和遗传学技术证明,核mGlu5受体激活后可在核内原位生成IP3。在HEK293细胞中表达阻...
