PSENEN
PSENEN，全稱為早老素增強子γ-分泌酶亞基（Presenilin enhancer gamma-secretase subunit），別名PEN-2、MDS033。PSENEN是γ-分泌酶復合體的核心組成之一，與早老素（PSEN1/PSEN2）、APH-1等蛋白共同參與跨膜蛋白的切割過程，例如淀粉樣前體蛋白（APP）經其剪切后產生β淀粉樣蛋白，這類蛋白異常沉積與阿爾茨海默病的病理特征密切相關。PSENEN通過調控Notch受體的活化影響細胞分化與發育，其功能異常可能引發家族性黑蒙癡呆等罕見遺傳病。近年來研究發現，PSENEN基因突變還與某些皮膚腫瘤的發生相關。在藥物研發領域，針對γ-分泌酶復合體的抑制劑（如Semagacestat）曾進入阿爾茨海默病臨床試驗，但因干擾Notch通路引發嚴重副作用而終止。目前研究轉向開發選擇性調節劑，試圖在減少β淀粉樣蛋白生成的同時保留Notch信號功能，相關化合物如Nirogacestat已在乳腺癌和硬纖維瘤領域開展II期試驗。

Recombinant Human Gamma-secretase subunit PEN-2 (PSENEN) (CSB-CF878932HU)
驗證數據
(Tris-Glycine gel) Discontinuous SDS-PAGE (reduced) with 5% enrichment gel and 15% separation gel.
PSENEN Antibody (CSB-PA878932OA01HU)
驗證數據
IHC image of CSB-PA878932OA01HU diluted at 1:400 and staining in paraffin-embedded human adrenal gland tissue performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a biotinylated secondary antibody and visualized using an HRP conjugated SP system.
