1. Mannose-binding lectin 2 (Mbl2) gene polymorphisms are related to protein plasma levels, but not to heart disease and infection by Chlamydia
The presence of the single nucleotide polymorphisms in exon 1 of the mannose-binding lectin 2 (MBL2) gene was evaluated in a sample of 159 patients undergoing coronary artery bypass surgery (71 patients undergoing valve replacement surgery and 300 control subjects) to investigate a possible association between polymorphisms and heart disease with Chlamydia i

2. Caracterização estrutural e funcional da proteína CsMAF1 de Citrus sinensis, parceira de interação do principal efetor tipo TAL de Xanthomonas citri / Structural and functional characterization of the Citrus sinensis protein CsMAF1, an interacting partner of the main type TAL effector of Xanthomonas citri
O cancro cítrico, causado pela bactéria Xanthomonas citri (X. citri), afeta a maioria das espécies de Citrus, ocorre praticamente em todos continentes e se destaca como uma séria ameaça à citricultura brasileira. O mecanismo molecular pelo qual X. citri causa cancro não é inteiramente conhecido, entretanto, sabe-se que a bactéria utiliza o sistema s

3. Fatores geneticos moduladores da gravidade clinica nas Beta-talassemias : o exemplo da proteina AHSP (Alpha Hemoglobin Stabilizing Protein)
Alpha-hemoglobin stabilizing protein (AHSP) is an erythroid-specific molecular chaperone that binds the cx-chains of hemoglobin, preventing their precipitation and deleterious effects. Loss of AHSP exacerbates a-globin precipitation and anemia in a murine model for p-thalassemia. In vitro, recombinant AHSP inhibits the production of reactive oxygen species (

4. Regulation of Flowering in Arabidopsis by an FLC Homologue
The Arabidopsis FLC gene encodes a MADS domain protein that acts as a repressor of flowering. Late-flowering vernalization-responsive ecotypes and mutants have high steady-state levels of FLC transcript, which decrease during the promotion of flowering by vernalization. Therefore, FLC has a central role in regulating the response to vernalization. We have is

5. MAF1, a novel plant protein interacting with matrix attachment region binding protein MFP1, is located at the nuclear envelope.
The interaction of chromatin with the nuclear matrix via matrix attachment region (MAR) DNA is considered to be of fundamental importance for chromatin organization in all eukaryotic cells. MAR binding filament-like protein 1 (MFP1) from tomato is a novel plant protein that specifically binds to MAR DNA. Its filament protein-like structure makes it a likely

6. Maf nuclear oncoprotein recognizes sequences related to an AP-1 site and forms heterodimers with both Fos and Jun.
The v-maf oncogene, identified from AS42 avian retrovirus, encodes a nuclear bZip protein. To elucidate the molecular mechanism of cell transformation induced by this oncogene, we determined the specific binding sequences of its product. Maf protein recognized two types of relatively long palindromic consensus sequences, TGCTGACTCAGCA and TGCTGACGTCAGCA, at

7. p38 MAPK Is a Major Regulator of MafA Protein Stability under Oxidative Stress
Mammalian MafA/RIPE3b1 is an important glucose-responsive transcription factor that regulates function, maturation, and survival of β-cells. Increased expression of MafA results in improved glucose-stimulated insulin secretion and β-cell function. Because MafA is a highly phosphorylated protein, we examined whether regulating activity of protein kinases ca

8. Bach proteins belong to a novel family of BTB-basic leucine zipper transcription factors that interact with MafK and regulate transcription through the NF-E2 site.
Members of the small Maf family (MafK, MafF, and MafG) are basic region leucine zipper (bZip) proteins that can function as transcriptional activators or repressors. The dimer compositions of their DNA binding forms determine whether the small Maf family proteins activate or repress transcription. Using a yeast two-hybrid screen with a GAL4-MafK fusion prote

9. Regulation of RNA Polymerase III Transcription Involves SCH9-dependent and SCH9-independent Branches of the Target of Rapamycin (TOR) Pathway*
Maf1 is a conserved repressor of transcription that functions at the downstream end of multiple nutrient and stress signaling pathways. How these different signaling pathways converge on Maf1 is not known. Previous work in yeast indicates that protein kinase A (PKA) regulates RNA polymerase (pol) III transcription, in part, by phosphorylating multiple si

10. Transcriptional stimulation of the retina-specific QR1 gene upon growth arrest involves a Maf-related protein.
The avian neural retina (NR) is derived from proliferating neuroectodermal precursors which differentiate after terminal mitosis and become organized in cell strata. Proliferation of postmitotic NR cells can be induced by infection with Rous sarcoma virus (RSV) and requires the expression of a functional v-Src protein. QR1 is a retina-specific gene expressed

11. MafB, a new Maf family transcription activator that can associate with Maf and Fos but not with Jun.
We have identified a new member of the maf oncogene family and named it mafB. This gene is expressed in a wide variety of tissues and encodes a protein of 311 amino acids containing a typical bZip motif in its carboxy-terminal region. In the bZip domain, MafB shares extensive homology not only with v-Maf but also with other Maf-related proteins. As expected

12. Functional implications from crystal structures of the conserved Bacillus subtilis protein Maf with and without dUTP
Three-dimensional structures of functionally uncharacterized proteins may furnish insight into their functions. The potential benefits of three-dimensional structural information regarding such proteins are particularly obvious when the corresponding genes are conserved during evolution, implying an important function, and no functional classification can be
