USP4, ubiquitin-specific protease 4, is also known as UNP, UNPH. USP4 is encoded by the human USP4 gene, which is localized in the 3p21.31 region of chromosome 3. USP4 is a deubiquitinating enzyme belonging to the family of cysteine proteases, which is capable of removing ubiquitination modifications from target proteins and regulating protein stability and function.
USP4 contains a DUSP-UBL structural domain and a UBL insertion catalytic structural domain, and shares the same domain organization with its cognate proteins, USP11 and USP15.
USP4 plays critical roles in a wide variety of cellular and biological processes, including maintenance of operational fidelity of the endoplasmic reticulum, modulation of cell proliferation and development, and key pathways of intrinsic immunity. When USP4 expression or activity is aberrant, it is associated with the progression of a variety of pathologies, particularly cancer.

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).
