Peptides corresponding to the N- and C-terminal parts of PEBP are well-structured in solution : new insights into their possible interaction with partners in vivo

Abstract :

Recently, it has been shown that mammalian PEBPs are implicated in several signalling pathways controlling the cellular cycle. In particular, during brain development, the N-terminal part of mammalian PEBP is specifically cleaved and the resulting 11 amino acid peptide stimulates the growth and activity of acetylcholinergic neurons. The crystallographic structure of bovine and human PEBPs has revealed that their N- and C-terminal parts are accessible and exposed to the solvent suggesting that they may be involved in specific interactions with cellular partners. We have chemically synthetized the two peptides corresponding to these terminal parts and studied their structure in solution by circular dichroism and NMR spectroscopies : both of them are well-structured.
