EIF5A

EIF5A,即真核翻译起始因子5A,别名eIF-5A、eIF5A-1。它是一种在真核细胞中高度保守的蛋白质,含有独特的多胺衍生氨基酸——羟腐胺赖氨酸(hypusine)。EIF5A的作用机制涉及到其独特的翻译后修饰——hypusination,这一过程由DHPS和DOHH催化,以多胺精胺为起始。这种修饰对EIF5A的活性至关重要,影响其在蛋白质合成中的功能。EIF5A通过缓解翻译延伸过程中核糖体在多种基序处的停滞,促进肽链的释放,增强翻译终止。EIF5A不仅参与蛋白质的合成,还涉及细胞自噬、细胞衰老、多胺稳态、能量代谢等一系列关键的细胞进程,并在癌症等多种疾病中发挥作用。EIF5A的活性受到其hypusination状态的严格调控,这一独特的修饰使其在细胞生命活动中扮演着重要角色。

CSB-RA932542A0HU

IHC image of CSB-RA932542A0HU diluted at 1:100 and staining in paraffin-embedded human colon cancer 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℃ overnight. The primary is detected by a Goat anti-rabbit IgG polymer labeled by HRP and visualized using 0.05% DAB.

CSB-RA932542A0HU

Immunofluorescence staining of Hela Cells with CSB-RA932542A0HU at 1:50, counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeated by 0.2% TritonX-100, and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4℃. Nuclear DNA was labeled in blue with DAPI. The secondary antibody was FITC-conjugated AffiniPure Goat Anti-Rabbit IgG (H+L).

Overlay histogram showing Jurkat cells stained with CSB-RA932542A0HU (red line) at 1:50. The cells were fixed with 70% Ethylalcohol (18h) and then incubated in 10% normal goat serum to block non-specific protein-protein interactions followedby the antibody (1µg/1*106 cells) for 1 h at 4℃.The secondary antibody used was FITC-conjugated goat anti-rabbit IgG (H+L) at 1/200 dilution for 30min at 4℃. Control antibody (green line) was Rabbit IgG (1µg/1*106 cells) used under the same conditions. Acquisition of >10,000 events was performed.
