1. Genome-wide identification and phylogenetic analysis of the ERF gene family in cucumbers
Members of the ERF transcription-factor family participate in a number of biological processes, viz., responses to hormones, adaptation to biotic and abiotic stress, metabolism regulation, beneficial symbiotic interactions, cell differentiation and developmental processes. So far, no tissue-expression profile of any cucumber ERF protein has been reported in

2. Determinação de motivos de ligação à quitina em vicilinas de Canavalia ensiformis e Vigna unguiculata através de métodos in silico e relação com suas toxicidades para o bruquídeo Callosobruchus maculatus (Coleoptera:Bruchidae)
Chitin is an important structural component of the cellular wall of fungi and exoskeleton of many invertebrate plagues, such as insects and nematodes. In digestory systems of insects it forms a named matrix of peritrophic membrane. One of the most studied interaction models protein-carbohydrate is the model that involves chitin-binding proteins. Among the in

3. Identificação e caracterização de elementos de transposição no genoma de Rhynchosciara / Identification e characterization of transposable elements in genome of Rhynchosciara
Transposable elements are discrete sequences that are able to move from one locus to another within the genome, constituting a significant part of eukaryotic genome. They are grouped into two main types, Class I elements transpose via an RNA intermediate (retrotransposon), and Class II elements transpose via a DNA "cut-and-paste" mechanism (transposons). The

4. Sinais de tráfego envolvidos no envolvidos no endereçamento do transportador vesicular de acetilcolina (VAChT)
The vesicular acetylcholine transporter (VAChT) is the protein responsible for packaging cytoplasmic acetylcholine (ACh) into the synaptic vesicle of cholinergic neurons. The cytosolic C-terminal region of VAChT is important in intracellular trafficking events and targeting to secretory organelles. In this study, we evaluate the existence of trafficking sign

5. Identificação e caracterização de uma proteína com motivos zinc finger de Trypanosoma cruzi
Zinc fingers are compact protein domains composed of a α-helix and a β-sheet held together by a zinc ion. Tandem arrays of zinc fingers are commonly used to recognize nucleic acids. Among other activities, they are involved in the processes of replication, transcription, and DNA repair. The nucleocapsid protein of HIV-1 contains a zinc finger motif

7. Ãndices Completos para Casamento de PadrÃes e InferÃncia de Motifs
Uma das maneiras mais eficientes (notadamente do ponto de vista computacional) empregada pela humanidade para a representaÃÃo da informaÃÃo tem sido atravÃs da forma de texto, ou seja, atravÃs de cadeias unimensionais de sÃmbolos (ou caracteres) tomados sobre conjuntos discretos finitos (ou alfabetos). As fecundas teorias, tÃcnicas e algoritmos desti

8. A Novel PF/PN Motif Inhibits Nuclear Localization and DNA Binding Activity of the ESX1 Homeoprotein
Despite their significance for mammalian embryogenesis, the molecular mechanisms that regulate placental growth and development have not been well defined. The Esx1 homeobox gene is of particular interest because it is among the few regulatory genes that have specific expression and function in the placenta during murine development. In addition, the ESX1 pr

9. The 3' untranslated region of localized maternal messages contains a conserved motif involved in mRNA localization.
Messenger RNA (mRNA) localization is emerging as a means of regulating gene expression. This process is operational in fly and frog development, where a subset of maternally inherited RNAs are asymmetrically distributed and thought to impart axial polarity to the embryo. Since most maternal mRNAs are uniformly distributed, an apparatus must exist to recogniz

10. Splicing Factor hSlu7 Contains a Unique Functional Domain Required to Retain the Protein within the NucleusD⃞
Precursor-mRNA splicing removes the introns and ligates the exons to form a mature mRNA. This process is carried out in a spliceosomal complex containing >150 proteins and five small nuclear ribonucleoproteins. Splicing protein hSlu7 is required for correct selection of the 3′ splice site. Here, we identify by bioinformatics and mutational analyses three f

11. Role of the Box C/D Motif in Localization of Small Nucleolar RNAs to Coiled Bodies and Nucleoli
Small nucleolar RNAs (snoRNAs) are a large family of eukaryotic RNAs that function within the nucleolus in the biogenesis of ribosomes. One major class of snoRNAs is the box C/D snoRNAs named for their conserved box C and box D sequence elements. We have investigated the involvement of cis-acting sequences and intranuclear structures in the localization of b

12. Integrase Mediates Nuclear Localization of Ty3
Retroviruses in nondividing cells and yeast retrotransposons must transit the nuclear membrane in order for integration to occur. Mutations in a bipartite basic motif in the carboxyl-terminal domain of the Ty3 integrase (IN) protein were previously shown to block transposition at a step subsequent to 3′-end processing of Ty3 extrachromosomal DNA. In this w
