Abstract
PED/PEA15 is a small protein involved in many protein-protein interactions that modulates the function of a number of key cellular effectors involved in major cell functions, including apoptosis, proliferation and glucose metabolism. In particular, PED/PEA15 interacts with the phospholipase D (PLD) isoforms 1 and 2 increasing protein kinase C-? isoform activity and affects both insulin-stimulated glucose transport and glucose-stimulated insulin secretion. The C-terminal portion (residues 712-1074) of PLD1, named D4, is still able to interact with PED/PEA15. In this study we characterized, by means of NMR spectroscopy, the molecular interaction of PED/PEA15 with D4?, a smaller region of D4, encompassing residues 712-818, shown to have the same affinity for PED/PEA15 and to induce the same effects as D4 in PED/PEA15-overexpressing cells. Chemical shift perturbation (CSP) studies allowed to define D4? binding site of PED/PEA15 and to identify a smaller region likely affected by an allosteric effect. Moreover, ELISA-like experiments showed that three 20-mer overlapping synthetic peptides, covering the 762-801 region of D4?, strongly inhibit PED/PEA15-D4? interaction through their binding to PED/PEA15 with KDs in low micromolar range. Finally, molecular details of the interaction of PED/PEA15 with one of the three peptides have been revealed by CSP and saturation transfer difference (STD) analyses.

Molecular basis of photochromism of a fluorescent protein revealed by direct 13C detection under laser illumination
Abstract Dronpa is a green fluorescent protein homologue with a photochromic property. A green laser illumination reversibly converts Dronpa from a green-emissive bright state to a non-emissive dark state, and ultraviolet illumination converts it to the bright state. We have employed solution NMR to understand the underlying molecular mechanism of the photochromism. The detail characterization of Dronpa is hindered as it is metastable in the dark state and spontaneously...
