1. O interactoma de Stanniocalcina-1 humana sugere novas funções e vias de atuação celulares / The interactome of human Stanniocalcin-1 suggests new cellular functions and pathways
O objetivo deste projeto foi estudar genes ativados em células do estroma da medula óssea, induzidos pela co-cultura com blastos leucêmicos, na tentativa de uma melhor compreensão sobre o crostalk entre estas células no microambiente tumoral. Nós identificamos Stanniocalcina-1 (STC1) como um potencial marcador molecular do microambiente tumoral, uma ve

2. Estudo dos ligantes da proteína prion celular com ênfase em estress inducible protein 1: modificação pós-traducional, tráfego e sinalização
A proteina prion celular (PrPC) constitui uma plataforma na membrana plasmatica capaz de interagir com diversos ligantes mediando a reuniao de complexos de sinalizacao na superficie celular. Um dos ligantes mais bem descritos para PrPC e a co-chaperonina Stress Inducible Protein1 ou STI1. STI1 e secretada por astrocitos e interage com PrPC na superficie neur

3. Modificação pós-traducional pendente de SUMO em Schistosoma mansoni: padrão de expressão diferencial durante a transição de cercária a esquistossômulo
Attachment of SUMO to target proteins occur through by similar mechanism to ubiquitination, with sequential action of three enzymes: E1 activating (Aos1-Uba2), E2 conjugation (Ubc9) and E3 ligases (PIAS, Polycomb2 and RanBP2). SUMO is synthesized as inactive precursors that require processing by specific proteases (SENPs). SUMO attachment is a reversible and

4. Clonagem e análise genética do gene iss, e avaliação da atividade do anticorpo IgY anti-proteína recombinante Iss de Escherichia coli patogênica para aves (APEC)
Escherichia coli strains designated as avian pathogenic E. coli (APEC) are responsible to avian colibacillosis, which is the principal cause of high economic losses in the modern poultry industry, due the increase of mortality, medication cost and condemnation of carcasses. The APEC pathogenicity is related to presence of several virulence factors, being the

5. Expressão e purificação de proteinas relacionadas a epilepsia / Expression and purification of epilepsy related proteins
Non-ion channel genes, as LGI1 and EFHC1, have been shown to indirectly affect ion channel currents in genetically determined epilepsy syndromes. LGI1 (Leucine-rich, glioma inactivated gene 1) is linked to a rare form of partial epilepsy (autosomal dominant partial epilepsy with auditory features, ADPEAF). Recently, LGI1 protein was associated with ADAM22 in

6. 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

7. Evaluation of Interactions of Human Cytomegalovirus Immediate-Early IE2 Regulatory Protein with Small Ubiquitin-Like Modifiers and Their Conjugation Enzyme Ubc9
The human cytomegalovirus (HCMV) major immediate-early protein IE2 is a nuclear phosphoprotein that is believed to be a key regulator in both lytic and latent infections. Using yeast two-hybrid screening, small ubiquitin-like modifiers (SUMO-1, SUMO-2, and SUMO-3) and a SUMO-conjugating enzyme (Ubc9) were isolated as IE2-interacting proteins. In vitro bindin

8. Small Ubiquitin-Like Modifier Modulates Abscisic Acid Signaling in Arabidopsis
Post-translational modification of proteins by small polypeptides, such as ubiquitin, has emerged as a common and important mechanism for regulating protein function. Small ubiquitin-like modifier (SUMO) is a small protein that is structurally related to but functionally different from ubiquitin. We report the identification and functional analysis of AtSUMO

9. SUMO-1 modification required for transformation by adenovirus type 5 early region 1B 55-kDa oncoprotein
SUMO-1 is a small ubiquitin-related modifier protein that is covalently linked to many cellular and viral protein targets. Modification by SUMO-1 is proposed to play a role in protein targeting and/or stability. We show here that adenovirus type 5 early region 1B 55-kDa (E1B-55kDa) oncoprotein can be covalently modified by SUMO-1 in vivo through a major

10. Identification of a SUMO-binding motif that recognizes SUMO-modified proteins
Posttranslational modification by the ubiquitin homologue, small ubiquitin-like modifier 1 (SUMO-1), has been established as an important regulatory mechanism. However, in most cases it is not clear how sumoylation regulates various cellular functions. Emerging evidence suggests that sumoylation may play a general role in regulating protein-protein interacti

11. SUMO-1 Modification of Human Cytomegalovirus IE1/IE72
Human cytomegalovirus (HCMV) immediate-early protein IE1/IE72 is involved in undermining many cellular processes including cell cycle regulation, apoptosis, nuclear architecture, and gene expression. The multifunctional nature of IE72 suggests that posttranslational modifications may modulate its activities. IE72 is a phosphoprotein and has intrinsic kinase

12. Covalent Modification of Human Immunodeficiency Virus Type 1 p6 by SUMO-1
The p6 domain of the human immunodeficiency virus type 1 (HIV-1) Gag polyprotein mediates virion budding from infected cells via protein-protein contacts with the class E vacuolar protein sorting factors, Tsg101 and AIP1/ALIX. Interaction with Tsg101 is strengthened by covalent attachment of monovalent ubiquitin to HIV-1 p6. To identify additional host facto
