Gene Name Pebp1
Protein Name Phosphatidylethanolamine-binding protein 1(PEBP-1)
Molecular Weight 20830 MW
Protein Function Binds ATP, opioids and phosphatidylethanolamine. Has lower affinity for phosphatidylinositol and phosphatidylcholine. Serine protease inhibitor which inhibits thrombin, neuropsin and chymotrypsin but not trypsin, tissue type plasminogen activator and elastase. Inhibits the kinase activity of RAF1 by inhibiting its activation and by dissociating the RAF1/MEK complex and acting as a competitive inhibitor of MEK phosphorylation (By similarity). .
Tissue Specificity HCNP is expressed in brain. Increased expression in aged senescence-accelerated mice.
Subcellular Localization Cytoplasm.
Uniprot ID P70296
Alternative Names Phosphatidylethanolamine-binding protein 1;PEBP-1;HCNPpp;Hippocampal cholinergic neurostimulating peptide;HCNP;Pebp1;Pbp, Pebp;

Background for Phosphatidylethanolamine-binding protein 1(PEBP-1)

PEBP1(Phosphatidylethanolamine-binding protein 1), also called PBP, RKIP, inhibits the phosphorylation and activation of MEK by RAF1. PEBP1 is identical to the phosphatidylethanolamine-binding protein(PBP) with a relative molecular mass of 23 kD. The PEBP1 gene is mapped on 12q24.23. PEBP1 coimmunoprecipitates with RAF1 and MEK from cell lysates and colocalizes with RAF1 when examined by confocal microscopy. PEBP1 overexpression interferes with the activation of MEK and ERK, induction of AP1-dependent reporter genes, and transformation elicited by an oncogenically activated RAF1 kinase. PEBP1 expression was rapidly upregulated during induction of chemotherapy-triggered apoptosis in human prostate and breast cancer cell lines, and maximal RKIP expression correlated perfectly with the onset of apoptosis by Chatterjee et al(2004). RKIP depletion decreased the mitotic index, the number of metaphase cells, traversal times from nuclear envelope breakdown to anaphase, and an override of mitotic checkpoints induced by spindle poisons.

Customer Q&As

Q: Do you offer BSA-free antibodies? Keyword: Bovine serum albumin, carrier protein, conjugation
A: Yes, please contact us at for more information about BSA-free antibodies and availability. The new BSA-free formula uses trehalose as a replacement to BSA. We have tested many alternative chemicals and found that trehalose protects the antibodies the best.
Q: Is your western blot protocol provided from the website applicable for all your antibodies? Keyword: applications, WB
A: The protocol is applicable for all our antibodies in WB, the NC Membrane(0.45μm or 0.22μm) and transfer time(70 mins or 50 mins) depends on the protein molecular weight, details can be found in included protocol.
Q: Can I conjugate markers to this antibody? Can I link custom conjugates to this antibody? Keyword: conjugation
A: The antibody is stored with BSA and cannot be conjugated with markers. Carrier free antibodies are available upon request. Please contact
Q: What should I use for negative control?
A: Please contact us for negative control suggestions. You can also check expression databases such as genecards, uniprot etc. Due to logistic reasons, we do not sell serum or lysates that we use internally for positive or negative control.
Q: Where can I find troubleshooting information? What should I do if I have unexpected bands, high background, no signal, weak signal
A: You can find Boster's troubleshoot guides under tech support tab. Please contact us for further assistance on troubleshooting your experiment.
Q: What is the immunogen sequence of this antibody? Is this antibody polyclonal or monoclonal?
A: You can find the immunogen sequence under "Immunogen" and clonality in the product name.
Q: What is the expected band size? Why is it different than the observed band size?
A: The expected band size is predicted on the size of the protein. The actual band size may be affected by a few other factors including but not limited to:
1. Post-translational modification:phosphorylation, methylation, glycosylation etc. These modifications prevent SDS molecules from binding to the target protein and thus make the band size appear larger than expected
2. Post-translational cleavage: this can cause smaller bands and or multiple bands

3. Alternative splicing: the same gene can have alternative splicing patterns generating different size proteins, all with reactivities to the antibody.

4. Amino Acid R chain charge: SDS binds to positive charges. The different size and charge of the Amino Acid side chains can affect the amount of SDS binding and thus affect the observed band size.
5. Multimers: Multimers are usually broken up in reducing conditions. However if the interactions between the multimers are strong, the band may appear higher.,
Q: What is the suggested dilution ratio for Western Blot (WB), Immunohistochemistry (IHC) and or ELISA standards? What is the optimal pH for the sample?
A: Check the datasheet for the product for details on dilution ratios for different experiments. You can find the datasheet button on the right side of the product page.
Q: What is the protocol you used for your Western blotting (WB) and Immunohistochemistry (IHC)?
A: Check our protocols under the tech support tab.
Q: What are some alternative names that could be used to describe this product?
A: Some common names include but are not limited to pbp antibody, rkip antibody
