Species Reactivity Note: The antibody has been directly tested for reactivity in Western blot with rat tissues. Biological Significance: Phosphatidylethanolamine binding protein (PEBP), also known as Raf kinase inhibitory protein (RKIP) is a highly conserved multifunctional protein that modulates the Raf/MAPK signaling cascade and has been implicated as a suppressor of metastatic cancer (Trakul N et al., 2005). PEBP has been shown to not only inhibit cell proliferation but also to induce differentiation of human keratinocytes (Yamazaki et al., 2004). Dysregulation of calpain activity results in cellular degeneration in conditions such as Alzheimer's disease and recently PEBP has been identified as a potential in vivo calpain substrate (Chen at al., 2006).

ncbi summary :
lipid binding protein; enhances acetylcholine synthesis in medial septal regions; human homolog (RKIP) has been shown to inhibit MEK- and ERK- signalling pathways [RGD, Feb 2006]
uniprot summary :
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 . By similarity. 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.HCNP may be involved in the function of the presynaptic cholinergic neurons of the central nervous system. HCNP increases the production of choline acetyltransferase but not acetylcholinesterase. Seems to be mediated by a specific receptor. Subunit structure: Has a tendency to form dimers by disulfide cross-linking. Interacts with RAF1 and this interaction is enhanced if RAF1 is phosphorylated on residues 'Ser-338', 'Ser-339', 'Tyr-340' and 'Tyr-341'. Interacts with ALOX15; in response to IL13/interleukin-13, prevents the interaction of PEBP1 with RAF1 to activate the ERK signaling cascade . By similarity. Subcellular location: Cytoplasm. Membrane; Peripheral membrane protein. Tissue specificity: Major component of epididymal secretions and sperm plasma membranes. It is present in cytosols from a variety of other tissues. Highly expressed in brain. Miscellaneous: Seems to be associated with memory and learning disorder. Sequence similarities: Belongs to the phosphatidylethanolamine-binding protein family.
