      Background InformationPhosphatidylethanolamine-binding protein 1 (UniProt: P30086; also known as PEBP-1, HCNPpp, Neuropolypeptide h3, Prostatic-binding protein, Raf kinase inhibitor protein, RKIP) is encoded by the PEBP1 (also known as PBP, PEBP) gene (Gene ID: 5037) in human. RKIP is as member of the phosphatidylethanolamine-binding-protein (PEBP) family that antagonizes multiple cell-survival pathways, such as the Ras-Raf-1, MEK/ERK, NF- B, and G-protein-coupled receptor Kinase 2 and thereby modulates cell growth, apoptosis, motility, invasion and metastasis. Over-expression of RKIP is shown to inhibit c-Src auto-phosphorylation and activation and IL-6-, JAK1 and 2-, and Raf-mediated STAT3 phosphorylation and activation. RKIP overexpression is shown to sensitize tumor cells to chemotherapeutic drug-induced apoptosis. Hence, it is considered as a suppressor of metastasis and a prognostic marker in several cancers. Clone 4A11 exhibits specific staining in formalin-fixed NIH3T3 cells transfected with GFP-PEBP1 and in some pancreatic cancer cells. (Ref.: Odabaei, G., et al. (2004). Adv.
