Human NY-REN-21 is a C2H2 type multi-finger protein, with a SCAN domain in the N-terminal region and a predicted coil central region. It represents a putative ortholog of mouse ZFP38, a transcriptional factor that recognizes a bipartite DNA motif and is unable to form homodimers. As shown in this work, NY-REN-21 contains a SCAN domain able to form(More)
Rab GTPases constitute the largest family of small monomeric GTPases, including over 60 members in humans. These GTPases share conserved residues related to nucleotide binding and hydrolysis, and main sequence divergences lie in the carboxyl termini. They cycle between inactive (GDP-bound) and active (GTP-bound) forms and the active site regions, termed(More)
In order to develop a high-efficiency and reproducible transformation protocol for Stylosanthes guianensis we assessed the biological and physical parameters affecting plant electroporation protoplasts. Energy input, as combinations of electric field strengths discharged by different capacitors, electroporation buffer and DNA form were evaluated.(More)
The Schistosoma mansoni fatty acid binding protein (FABP), Sm14, is a vaccine candidate against, S. mansoni and F. hepatica. Previously, we demonstrated the importance of a correct fold to achieve protection in immunized animals after cercariae challenge [[10]. C.R.R. Ramos, R.C.R. Figueredo, T.A. Pertinhez, M.M. Vilar, A.L.T.O. Nascimento, M. Tendler, I.(More)
Nuclear receptors are ligand-inducible transcription factors that share structurally related DNA-binding (DBD) and ligand-binding (LBD) domains. Biochemical and structural studies have revealed the modular nature of DBD and LBD. Nevertheless, the domains function in concert in vivo. While high-resolution crystal structures of nuclear receptor DBDs and LBDs(More)
Root bark of West African tree Diospyros batocana Hiern, Ebenaceae, was examined. On the basis of chromatographic and spectral analysis it was shown to contain the naphtaquinones 7-methyljuglone, 2-methylnaphthazarin, biramentaceone, rotundiquinone, mamegakinone, diospyrin, diosquinone, isodiospyrin and batocanone. This last compound proved to be the(More)
An effective protocol to generate stable transformants of the tropical forage legume Stylosanthes guianensis (Aubl.) Sw. in a selection-free system was developed. Based on transient reporter gene expression, we have obtained transformation rates of 3.47% using 30-day-old calli as target, 1300 psi helium pressure, 12.5 cm microprojectile flight distance,(More)
