The INhibitor of Growth (ING) family of tumor suppressors regulates the transcriptional state of chromatin by recruiting remodeling complexes to sites with histone H3 trimethylated at position K4 (H3K4me3). This modification is recognized by the plant homeodomain (PHD) present at the C-terminus in the five members of the ING family. ING4 facilitates histone(More)
Heme-linked proteins, such as cytochromes, are popular subjects for protein folding studies. There is the underlying question of whether the heme affects the structure of the denatured state by cross-linking it and forming other interactions, which would perturb the folding pathway. We have studied wild-type and mutant cytochrome b562 from Escherichia coli,(More)
Plant homeodomain (PHD) fingers are frequently present in proteins involved in chromatin remodelling, and some of them bind to histones. The family of proteins inhibitors of growth (ING) contains a PHD finger that bind to histone-3 trimethylated at lysine 4, and those of ING1 and ING2 also act as nuclear phosphoinositide receptors. We have determined the(More)
The structure of the tick carboxypeptidase inhibitor (TCI) and its backbone dynamics, free and in complex with human carboxypeptidase B, have been determined by NMR spectroscopy. Although free TCI has the same overall fold as that observed in the crystal structures of its complexes with metallocarboxypeptidase types A and B, there are structural differences(More)
Antiangiogenic therapy is nowadays one of the most active fields in cancer research. The first strategies, aimed at inhibiting tumor vascularization, included upregulation of endogenous inhibitors and blocking of the signals delivered by angiogenic factors. But interaction between endothelial cells and their surrounding extracellular matrix also plays a(More)
We present in this paper how to apply to mathematical formulae a generic recognition method already used for musical scores, table structure and old forms recognition. We propose to use this method to recognize the structure of formulae and also to recognize some symbols made of line segments. This offers two possibilities: improving the symbol recognition(More)
The folding of CheY mutant F14N/V83T was studied at 75 residues by NMR. Fluorescence, NMR, and sedimentation equilibrium studies at different urea and protein concentrations reveal that the urea-induced unfolding of this CheY mutant includes an on-pathway molten globule-like intermediate that can associate off-pathway. The populations of native and(More)
The popularity of multimedia applications has resulted in increased interest in efficient implementation of multicasting. Wavelength division multiplexing (WDM) is a promising technology for backbone networks, because they provide high bandwidth and methods for control and managment. Since not every switches are equipped with wavelength conversion facility,(More)
