CANX

钙连接蛋白(Calnexin,别名IP90)是一种广泛表达于内质网的分子伴侣蛋白,主要负责协助新生糖蛋白的正确折叠与质量控制。CANX通过识别未完全折叠蛋白的糖基化修饰,与钙网蛋白协同形成"折叠检查系统",阻止错误折叠蛋白分泌或促进其进入降解途径。该蛋白在维持内质网稳态中发挥关键作用,其功能异常与阿尔茨海默病、帕金森病等神经退行性疾病密切相关,错误折叠蛋白的积累会触发细胞凋亡通路。在肿瘤领域,某些癌细胞通过上调钙连接蛋白增强应激耐受性,促进转移和耐药性形成。CANX还参与调控免疫细胞表面MHC-I类分子的组装,影响抗原呈递过程。针对其相关通路开发的分子伴侣抑制剂已进入临床前研究,如选择性抑制内质网应激通路的小分子化合物,在乳腺癌和骨髓瘤模型中显示出增强化疗敏感性的潜力。基于其多重生物学功能,钙连接蛋白已成为神经疾病和肿瘤治疗的新兴靶点。

CSB-MA004485A1m

Immunofluorescence staining of Hela cells with CANX CSB-MA004485A1m at 1:140, counter-stained with DAPI. The cells were fixed in 4% formaldehyde and blocked in 10% normal Goat Serum. The cells were incubated with the antibody overnight at 4°C. Nuclear DNA was labeled in blue with DAPI. The secondary antibody was FITC-conjugated AffiniPure Goat Anti-Mouse IgG (H+L).

CSB-MA004485A1m

Immunofluorescence staining of HepG2 cells with CANX CSB-MA004485A1m at 1:140, counter-stained with DAPI. The cells were fixed in 4% formaldehyde and blocked in 10% normal Goat Serum. The cells were incubated with the antibody overnight at 4°C. Nuclear DNA was labeled in blue with DAPI. The secondary antibody was FITC-conjugated AffiniPure Goat Anti-Mouse IgG (H+L).

CSB-MA004485A1m

Overlay Peak curve showing Hela cells stained with CSB-MA004485A1m (red line) at 1:140. The cells were incubated in 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (1µg/1*106cells) for 1h at 4°C. The secondary antibody used was FITC-conjugated Goat Anti-Mouse IgG(H+L) at 1/100 dilution for 30min at 4°C. Isotype control antibody (green line) was mouse IgG1 (1µg/1*106cells) used under the same conditions. Acquisition of >10,000 events was performed.
