13. Estudo funcional e estrutural de Nip7p, uma proteina conservada envolvida na sintese de ribossomos / Functional and structural analysis of Nip7p, a conserved protein involved in ribosome biogenesis
A síntese de ribossomos é um processo conservado em eucariotos e se inicia com a transcrição dos rRNAs no nucléolo. Mais de 170 fatores atuam de forma transitória no processamento dos precursores para gerar os rRNAs maduros que formarão as subunidades ribossomais no citoplasma. Entre as proteínas envolvidas na síntese de ribossomos está a Nip7p, um

14. Analysis of the interaction between human kidney anion exchanger 1 and kanadaptin using yeast two-hybrid systems
Kidney anion exchanger adaptor protein (Kanadaptin) is a protein which interacts with the cytoplasmic N-terminal domain of kidney anion exchanger 1 (kAE1) and was first detected in mice using the yeast two-hybrid system and was also found to co-localize with kAE1 in rabbit a-intercalated cells. Impaired trafficking of human kAE1 can result in the kidney dise

15. PROTEIN-PROTEIN INTERACTION ANALYSIS OF THE DEFENSIN PSD1 FROM PISUM SATIVUM WITH NEUROSPORA CRASSA PROTEINS / ANÁLISE DA INTERAÇÃO PROTÉICA DA DEFENSINA PSD1 DE PISUM SATIVUM COM PROTEÍNAS DO FUNGO NEUROSPORA CRASSA
Plant defensins, innate components of the plant immune system, are cationic, antifungal peptides, with a cysteine- rich primary structure. Evidence from the literature demonstrated that fungus membrane patches containing complex sphingolipids, mannosyldiinositolphosphorylceramide and glucosylceramides, are selective binding sites for the plant defensins isol

16. Analise das proteinas Ki-1/57 e PRMT1 : identificação, mapeamento e caracterização funcional da interação com outras proteinas / Analysis of the proteins Ki-1/57 and PRMT1: identification, mapping and characterization of the interaction with other proteins
The protein Ki-1/57 that is found both in the cytoplasm and nucleus is associated with serine/threonine protein kinase activity and gets phosphorylated on serine and threonine residues upon cellular activation. We demonstrated that Ki-1/57 interacts with the Chromatin-Helicase-DNA-binding domain protein 3 (CHD3) and with the adaptor/signaling protein RACK1 i

17. Analises estruturais e estudos das interações das proteinas INT6 e NY-REN-21 / Structural analysis and interaction studies of the INT6 and NY-REN-sa proteins
O gene que codifica a proteína INT6 corresponde a um dos sítios de inserção do vírus de tumor de glândula mamária em camundongo (MMTV). Esta inserção pode levar à formação de proteínas truncadas sem a porção C-terminal e sem o domínio PCI, descrito como domínio de interação entre proteínas. Neste trabalho, realizamos 3 triagens para a ide

18. A calcineurin inhibitory protein overexpressed in Down's syndrome interacts with the product of a ubiquitously expressed transcript
The Down's syndrome candidate region 1 (DSCR1) protein, encoded by a gene located in the human chromosome 21, interacts with calcineurin and is overexpressed in Down's syndrome patients. As an approach to clarifying a putative function for this protein, in the present study we used the yeast two-hybrid system to identify DSCR1 partners. The two-hybrid system

19. The 42-kDa coat protein of Andean potato mottle virus acts as a transcriptional activator in yeast
Interactions of viral proteins play an important role in the virus life cycle, especially in capsid assembly. Andean potato mottle comovirus (APMoV) is a plant RNA virus with a virion formed by two coat proteins (CP42 and CP22). Both APMoV coat protein open reading frames were cloned into pGBT9 and pGAD10, two-hybrid system vectors. HF7c yeast cells transfor

20. The reverse two-hybrid system: a genetic scheme for selection against specific protein/protein interactions.
The yeast two-hybrid system is a powerful experimental approach for the characterization of protein/ protein interactions. A unique strength of the yeast two-hybrid system is the provision for genetic selection techniques that enable the identification of specific protein/protein interactions. We now report the development of a modified yeast two-hybrid syst

21. Reverse two-hybrid and one-hybrid systems to detect dissociation of protein-protein and DNA-protein interactions.
Macromolecular interactions define many biological phenomena. Although genetic methods are available to identify novel protein-protein and DNA-protein interactions, no genetic system has thus far been described to identify molecules or mutations that dissociate known interactions. Herein, we describe genetic systems that detect such events in the yeast Sacch

22. A positive genetic selection for disrupting protein–protein interactions: Identification of CREB mutations that prevent association with the coactivator CBP
The Escherichia coli tet-repressor (TetR) operator system was used to develop a variation of the yeast two-hybrid assay in which disruptions of protein–protein interactions can be identified by a positive selection. This assay, designated the “split-hybrid system,” contains a two-component reporter. The first component contains LexA binding sites

23. Protein-peptide interactions analyzed with the yeast two-hybrid system.
The yeast two-hybrid system was used to screen a library of random peptides fused to a transcriptional activation domain in order to identify peptides capable of binding to the retinoblastoma protein (Rb). Seven peptides were identified, all of which contain the Leu-X-Cys-X-Glu motif found in Rb-binding proteins, although their activity in the yeast assay va

24. Genetic Analysis of nif Regulatory Genes by Utilizing the Yeast Two-Hybrid System Detected Formation of a NifL-NifA Complex That Is Implicated in Regulated Expression of nif Genes
In diazotrophic organisms, nitrogenase synthesis and activity are tightly regulated. Two genes, nifL and nifA, are implicated as playing a major role in this regulation. NifA is a transcriptional activator, and its activity is inhibited by NifL in response to availability of excess fixed nitrogen and high O2 tension. It was postulated that NifL binds to NifA
