PEBP1 encodes phosphatidylethanolamine-binding protein 1, a highly conserved protein also known as Raf kinase inhibitor protein (RKIP). It functions as a molecular scaffold and modulator of multiple signaling pathways by interacting with key kinases and phosphatases. PEBP1 regulates the MAPK/ERK pathway through direct binding to Raf-1, inhibiting downstream signaling, and also modulates GPCR signaling and NF-κB activation by interacting with GRK2 and TAK1, respectively.
Dysregulation of PEBP1 is associated with various cancers, where its downregulation correlates with increased metastasis and poor prognosis due to aberrant MAPK and NF-κB signaling. Emerging studies highlight its potential as a therapeutic target; small-molecule agonists aiming to restore PEBP1 function are under preclinical evaluation for cancer treatment, with promising results in inhibiting tumor cell migration and invasion.

IHC image of CSB-RA903387A0HU diluted at 1:100 and staining in paraffin-embedded human prostate 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 Goat anti-rabbit polymer IgG labeled by HRP and visualized using 0.05% DAB.

Immunofluorescence staining of HepG2 cell with CSB-RA903387A0HU at 1:50, 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).
Overlay Peak curve showing PC-3 cells stained with CSB-RA903387A0HU (red line) at 1:100. The cells were fixed in 4% formaldehyde and permeated by 0.2% TritonX-100 for 10min. Then 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (1ug/1*106cells) for 45min at 4℃. The secondary antibody used was FITC-conjugated goat anti-rabbit IgG (H+L) at 1/200 dilution for 35min at 4℃.Control antibody (green line) was Rabbit IgG (1ug/1*106cells) used under the same conditions. Acquisition of >10,000 events was performed.
