Western Blotting

Western Blotting

Western blot analysis of extracts from rat brain, either sham-operated, 15 min ischemia followed by 4 h reperfusion, or 15 min ischemia only, using Phospho-PSD93 (Tyr340) Antibody (upper) or PSD95 Antibody (lower).

Postsynaptic Density Protein 93 (PSD93) is a member of the PSD subfamily of the membrane-associated guanylate kinase (PSD-MAGUK) proteins. Structurally, it most closely resembles PSD95, consisting of an N-terminal variable segment followed by three PDZ domains, an SH3 domain and an inactive guanylate kinase (GK) domain (1,2) . PSD93 is expressed in neuronal cells and located at the synapse where it interacts with neuronal receptors and proteins including the NMDA receptor (2-4), K+ channels (5-6), and the AMPA receptor (7) to regulate their membrane localization and neuronal signaling. PSD93 is implicated in postsynaptic related persistent pain induction and is a potential target for treatment of this syndrome (3).The phosphorylation site at Tyr340 of PSD93 was identified at Cell Signaling Technology (CST) using PhosphoScan®, CST's MS/MS platform for phosphorylation site discovery. Phosphorylation of PSD93 at Tyr340 was observed in extracts isolated from reperfusion of ischemic rat brain.

突触后密集区蛋白93 (Postsynaptic Density protein 93,PSD93) 是一种膜相关鸟苷酸激酶(PSD - MAGUK)蛋白质PSD亚族的成员。结构上,它最类似于PSD95,由三个PDZ结构域后的可变N末端,一个SH3结构域和一个无效的鸟苷酸激酶(GK)结构域组成(1,2)。PSD93在神经细胞表达,定位于突出,与包括NMDA受体(2-4),K+通道(5-6),AMPA受体(7)等神经受体和蛋白质相互作用,调节自己的膜定位和神经信号。PSD93与持续性疼痛感应的突触后事件有关,是一种用于治疗此综合征的潜在的目标(3)。PSD93的Tyr340磷酸化位点由CST公司使用PhosphoScan®和CST的磷酸化位点质谱平台发现。PSD93在Tyr340上的磷酸化在缺血再灌注的大鼠脑组织分离提取物中可见。
