Résumé
Proteins of the phosphatidylethanolamine binding protein(PEBP) family are highly conserved throughout nature and have multiple biological functions.These small,cytosolic proteins have a typical large central sheet and a putative ligand-binding site which shares an affinity for a variety of ligands such as phospholipids,opioids,nucleotides,hydrophobic odorant molecules.PEBP plays a pivotal modulatory role in Raf-1/MEK/ERK、I?B/NF-?B、GPCR signaling cascades.As the precursor of the hippocampal cholinergic neurostimulating peptide(HCNP),PEBP may play an important role in the septal cholinergic development of the hippocampal.In addition,PEBP has the potential to contribute to neural protection,biogenesis and refinement of the membrane,Alzheimers disease(AD),opioid dependence,diabetic nephropathy,cancer and other physiological or pathophysiological processes.
