USP4
USP4,即泛素特异性蛋白酶4,也称为UNP、UNPH。USP4由人类USP4基因编码,该基因定位于染色体3的3p21.31区域。USP4是一种去泛素化酶,属于半胱氨酸蛋白酶家族,能够从目标蛋白质上去除泛素化修饰,调节蛋白质的稳定性和功能。
USP4含有DUSP-UBL结构域和一个UBL插入催化结构域,与其同源蛋白USP11和USP15共享相同的结构域组织。USP4在多种细胞和生物学过程中发挥关键作用,包括维持内质网的操作保真度、调节细胞增殖和发育以及固有免疫的关键途径。当USP4的表达或活性异常时,它与多种病理状态的进展有关,尤其是癌症。

IHC image of CSB-PA614393LA01HU diluted at 1:500 and staining in paraffin-embedded human kidney 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.

IHC image of CSB-PA614393LA01HU diluted at 1:500 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°C overnight. The primary is detected by a biotinylated secondary antibody and visualized using an HRP conjugated SP system.

Immunofluorescence staining of U251 cells with CSB-PA614393LA01HU at 1:166, counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C. The secondary antibody was Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L).
