1. Genome-wide Identification, Classification and Expression Analysis of the Mildew Resistance Locus O ( MLO ) Gene Family in Sweet Orange ( Citrus sinensis )
ABSTRACT Mildew resistance Locus O (MLO), a gene family specific to plants, plays significant roles in the resistance to powdery mildew (PM) and response to a variety of abiotic stresses, plant growth and development. Despite their importance as barley, rice, wheat, few studies are reported in dicots except Arabidopsis; no global analysis has been performed

2. Identification of alternative transcripts of rat CD9 expressed by tumorigenic neural cell lines and in normal tissues
CD9 is the best-studied member of the tetraspanin family of transmembrane proteins. It is involved in various fundamental cellular processes and its altered expression is a characteristic of malignant cells of different origins. Despite numerous investigations confirming its fundamental role, the heterogeneity of CD9 or other tetraspanin proteins was conside

3. Retention of a recombinant GFP protein expressed by the yellow fever 17D virus in the E/NS1 intergenic region in the endoplasmic reticulum
The flaviviral envelope proteins, E protein and precursor membrane protein, are mainly associated with the endoplasmic reticulum (ER) through two transmembrane (TM) domains that are exposed to the luminal face of this compartment. Their retention is associated with the viral assembly process. ER-retrieval motifs were mapped at the carboxy terminus of these e

4. Search for a platelet-activating factor receptor in the Trypanosoma cruzi proteome: a potential target for Chagas disease chemotherapy
Chagas disease (CD) causes the highest burden of parasitic diseases in the Western Hemisphere and is therefore a priority for drug research and development. Platelet-activating factor (PAF) causes the CD parasite Trypanosoma cruzi to differentiate, which suggests that the parasite may express PAF receptors. Here, we explored the T. cruzi proteome for PAF rec

5. Caracterização e expressão do gene SERK durante a indução de embriogênese somática em soja / Characterization and expression of SERK gene during induction of somatic embryogenesis in soybean
Somatic embryogenesis is a useful tool for plant propagation and a suitable model system for deciphering early events during embryo development. Molecular and genetic studies focused in plant development have reported the involvement of SERK (Somatic Embryogenesis Receptor Kinase) gene in the acquisition of embryogenic competence. In order to increase the ef

6. Iron homeostasis related genes in rice
Iron is essential for plants. However, excess iron is toxic, leading to oxidative stress and decreased productivity. Therefore, plants must use finely tuned mechanisms to keep iron homeostasis in each of their organs, tissues, cells and organelles. A few of the genes involved in iron homeostasis in plants have been identified recently, and we used some of th

7. Characterization of the effect of an aminophospholipid (APLT) from Leishmania (Leishmania) amazonensis on phosphatidylserine exposure. / Caracterização do efeito de uma translocase de aminofosfolipídio (APLT) de Leishmania (Leishmania) amazonensis na exposição de fosfatidilserina.
O mecanismo responsável pela exposição da fosfatidilserina (PS) nas membranas celulares não está bem definido. Uma atividade dependente de ATP está envolvida, provavelmente uma ATPase tipo-P. ATPases tipo P são uma família de proteínas transmembranares envolvidas no transporte de metais, íons e fosfolipídios através da membrana plasmática. As P4

8. Identification of citrus expressed sequence tags (ESTs) encoding pleiotropic drug resistance (PDR)-like proteins
Pleiotropic drug resistance (PDR) proteins, a subfamily of the ATP-binding cassette (ABC) transporters, have been recently shown to play a role in plant defense against biotic and abiotic stresses. However, nothing is known about their expression in citrus. To investigate the occurrence of PDR homologues in citrus species, we have surveyed EST sequences from

9. Specific structural features of syndecans and heparan sulfate chains are needed for cell signaling
The syndecans, heparan sulfate proteoglycans, are abundant molecules associated with the cell surface and extracellular matrix and consist of a protein core to which heparan sulfate chains are covalently attached. Each of the syndecan core proteins has a short cytoplasmic domain that binds cytosolic regulatory factors. The syndecans also contain highly conse

10. Role of protease-activated receptor-2 in inflammation, and its possible implications as a putative mediator of periodontitis
Proteinase-activated receptor-2 (PAR2) belongs to a novel subfamily of G-protein-coupled receptors with seven-transmembrane domains. This receptor is widely distributed throughout the body and seems to be importantly involved in inflammatory processes. PAR2 can be activated by serine proteases such as trypsin, mast cell tryptase, and bacterial proteases, suc

12. Identification and characterization of phosphate transporters genes in sugarcane (Saccharum spp.). / Identificação e caracterização de genes de transportadores de fósforo em cana-de-açúcar (Saccharum spp.).
Brazil is rsponsible for 25% of the world production of sugarcane (Saccharum spp.), and the economic importance of this crop is related to its increasing use as energy source and sugar. Traditional genetic breeding programs are hamperd by the genomic complexity, derived from its multi-specific origing adn polyploidy. The availability of inorganic phosphorous
