1. Unraveling the evolutionary scenario of the hobo element in populations of Drosophila melanogaster and D. simulans in South America using the TPE repeats as markers
Abstract Transposable elements (TEs) are nucleotide sequences found in most studied genomes. These elements are highly diversified and have a large variation in nucleotide structure and mechanisms of transposition. hobo is a member of class II, belonging to hAT superfamily, described inDrosophila melanogaster, and it presents in its Open Reading Frame, a rep

2. Evolutionary history of the Tip100 transposon in the genus Ipomoea
Tip100 is an Ac-like transposable element that belongs to the hAT superfamily. First discovered in Ipomoea purpurea (common morning glory), it was classified as an autonomous element capable of movement within the genome. As Tip100 data were already available in databases, the sequences of related elements in ten additional species of Ipomoea and five commer

3. Mecanismos intraflagelares de transporte e trânsito de proteínas: uma abordagem pós-genômica e computacional de caracterização da virulência flagelar em Leishmania spp. / Intraflagelares mechanisms of transport and transit proteins: a post-genomics and computational characterization of virulence flagellar Leishmania spp.
Leishmania are flagellated protozoa that cause a main neglected diseasease, collectively known as leishmaniases, posing a constant challenge for the control and prevention of the disease due to the wide-world distribution and prevalence of these parasites. As an insinuating pathogen, Leishmania has a specialized organelle for motility, the flagellum, which i

4. Estudo de dois grupos de elementos de cana-de-açúcar homológos à superfamília hAT de transposons / Studies on hAT-like transposases in sugarcane superfamily
Transposable elements (TEs) are mobile genetic sequences. Their mutagenic capacity makes them important sources of variation in the genomes. These elements have another important evolutionary role as donors of functional protein domains in the formation of new genes. 276 cDNA clones homologous to TEs were previously identified in the Brazilian Sugarcane Expr

5. Mx-rMx, a Family of Interacting Transposons in the Growing hAT Superfamily of MaizeW⃞
More than half a century after the discovery of transposable elements, the number of genetically defined autonomous elements that have been isolated and characterized molecularly in any one species remains surprisingly small. Because of its rich genetic history, maize (Zea mays) is, by far, the plant with the largest number of such elements. Yet, even in mai

6. A Highly Conserved Domain of the Maize Activator Transposase Is Involved in Dimerization
Previous studies have presented indirect evidence that the transposase of the maize transposable element Activator (TPase) is active as an oligomer and forms inactive macromolecular complexes expressed in large amounts. Here, we have identified and characterized a dimerization domain at the C terminus of the protein. This domain is the most highly conserved

7. Acetylation of Histones and Transcription-Related Factors
The state of chromatin (the packaging of DNA in eukaryotes) has long been recognized to have major effects on levels of gene expression, and numerous chromatin-altering strategies—including ATP-dependent remodeling and histone modification—are employed in the cell to bring about transcriptional regulation. Of these, histone acetylation is one of the best

8. Crystal structure and mechanism of histone acetylation of the yeast GCN5 transcriptional coactivator
The yeast GCN5 (yGCN5) transcriptional coactivator functions as a histone acetyltransferase (HAT) to promote transcriptional activation. Here, we present the high resolution crystal structure of the HAT domain of yGCN5 and probe the functional importance of a conserved glutamate residue. The structure reveals a central protein core associated with AcCoA bind
