RIOK2 encodes RIO kinase 2, a serine/threonine kinase also known as RIOK-2 or DKFZp686A1315. It is critical for 40S ribosomal subunit maturation, mediating the final cleavage of the 18S rRNA precursor during ribosome biogenesis. RIOK2 interacts with ribosome assembly factors and is regulated by the mTOR pathway, which controls cell growth and protein synthesis.
Overexpression of RIOK2 is associated with colorectal, breast, and lung cancers, driving tumor proliferation and metastasis. No approved drugs target RIOK2 yet, but preclinical studies are exploring small-molecule inhibitors of its kinase activity as potential anticancer therapies, especially for tumors with high RIOK2 expression.
RIOK2 Antibody (CSB-PA887136LA01HU)
Validated Data
IHC image of CSB-PA887136LA01HU diluted at 1:400 and staining in paraffin-embedded human placenta 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-PA887136LA01HU diluted at 1:400 and staining in paraffin-embedded human appendix 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.
Immunofluorescence staining of HepG2 cells with CSB-PA887136LA01HU at 1:133, 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).
