GRIN2A

这个基因编码谷氨酸门控离子通道蛋白家族的一个成员。编码蛋白是n-甲基-d-天冬氨酸（nmda）受体亚单位。nmda受体既依赖于配体门控，又依赖于电压，并参与长期增强，一种依赖于活动的突触传递效率的提高，被认为是某种记忆和学习的基础。这些受体对钙离子具有渗透性，其激活导致钙离子流入突触后细胞，从而激活多个信号级联。这种基因的破坏与局灶性癫痫和言语障碍有关，不论是否有认知障碍。选择性剪接导致多个转录变体。[由RefSeq提供，2014年5月]
This gene encodes a member of the glutamate-gated ion channel protein family. The encoded protein is an N-methyl-D-aspartate (NMDA) receptor subunit. NMDA receptors are both ligand-gated and voltage-dependent, and are involved in long-term potentiation, an activity-dependent increase in the efficiency of synaptic transmission thought to underlie certain kinds of memory and learning. These receptors are permeable to calcium ions, and activation results in a calcium influx into post-synaptic cells, which results in the activation of several signaling cascades. Disruption of this gene is associated with focal epilepsy and speech disorder with or without cognitive disability. Alternative splicing results in multiple transcript variants.
