1. Estudos funcionais e estruturais das septinas humanas 6, 8 e 10 / Functional and structural studies of human septin 6, 8 and 10
A cell passes through some steps to enable for cell division and all these processes are called Cell Cycle. The spatial and temporal regulation of this process is crucial to maintaining cellular and genetic material. Failure in this process can lead to cell death or genetic changes causing division and unregulated growth of tumors. Among several proteins inv

2. Caracterização funcional e estrutural das septinas humanas 1, 6 e 8 / Functional and structural characterization of human septins 1, 6 and 8
Septins have a central domain which binds GTP (GTPase domain) and two other variable domains at their N- and C-termim Their principal characteristic is the ability to bind to other septins, thereby forming filaments. This is intimately related to their functions in cytokinesis, exocytosis, and apoptosis, among others. They are also directly or indirectly ass

3. Análise proteômica comparativa entre neutrófilos quiescentes e neutrófilos ativado por n-formil-metionil-leucil-fenilalanina (fmlp)
Os neutrófilos são células do sistema imune responsáveis pelo combate inicial contra microrganismos, tais como bactérias e fungos. Possuem uma vida curta, em torno de 6 a 10h na circulação periférica sendo os primeiros a chegarem ao local injuriado. Os neutrófilos podem ser ativados por várias substâncias, entre elas o fMLP (N-formil Metionil-Leuc

4. Estudos das interações da septina 4 humana / Study of Human Septin 4 interactions
Septinas são proteínas ligantes a GTP encontradas desde fungos até metazoários. A primeira função identificada para septinas foi o seu papel central na organização e dinâmica do septo de divisão de leveduras. Uma das características marcantes é que septinas se organizam em heterofilamentos de 7 a 9 nm de espessura que foram purificados de diverso

5. Estudos estruturais da septina humana SEPT11 / STRUCTURAL STUDIES OF THE HUMAN SEPTIN SEPT11
Septinas são proteínas de ligação ao nucleotídeo de guanina (GTP). Foram inicialmente identificadas em fungos e atuam na fase final da divisão celular. Posteriormente, também verificaram que esta família de proteínas está presente em outros eucariotos com exceção de plantas. Septinas são purificadas de fungos Saccharomyces cerevisiae, Drosophila

6. Septin 11 Is Present in GABAergic Synapses and Plays a Functional Role in the Cytoarchitecture of Neurons and GABAergic Synaptic Connectivity*
Mass spectrometry and immunoblot analysis of a rat brain fraction enriched in type-II postsynaptic densities and postsynaptic GABAergic markers showed enrichment in the protein septin 11. Septin 11 is expressed throughout the brain, being particularly high in the spiny branchlets of the Purkinje cells in the molecular layer of cerebellum and in the olfactory

7. Protein–Protein Interactions Governing Septin Heteropentamer Assembly and Septin Filament Organization in Saccharomyces cerevisiae
Mitotic yeast (Saccharomyces cerevisiae) cells express five related septins (Cdc3, Cdc10, Cdc11, Cdc12, and Shs1) that form a cortical filamentous collar at the mother-bud neck necessary for normal morphogenesis and cytokinesis. All five possess an N-terminal GTPase domain and, except for Cdc10, a C-terminal extension (CTE) containing a predicted coiled coil

8. Bni5p, a Septin-Interacting Protein, Is Required for Normal Septin Function and Cytokinesis in Saccharomyces cerevisiae
In the budding yeast Saccharomyces cerevisiae, the Cdc3p, Cdc10p, Cdc11p, Cdc12p, and Sep7p/Shs1p septins assemble early in the cell cycle in a ring that marks the future cytokinetic site. The septins appear to be major structural components of a set of filaments at the mother-bud neck and function as a scaffold for recruiting proteins involved in cytokinesi

9. Molecular Dissection of a Yeast Septin: Distinct Domains Are Required for Septin Interaction, Localization, and Function
The septins are a family of cytoskeletal proteins present in animal and fungal cells. They were first identified for their essential role in cytokinesis, but more recently, they have been found to play an important role in many cellular processes, including bud site selection, chitin deposition, cell compartmentalization, and exocytosis. Septin proteins self

10. Septins, under Cla4p Regulation, and the Chitin Ring Are Required for Neck Integrity in Budding Yeast
CLA4, encoding a protein kinase of the PAK type, and CDC11, encoding a septin, were isolated in a screen for synthetic lethality with CHS3, which encodes the chitin synthase III catalytic moiety. Although Ste20p shares some essential function with Cla4p, it did not show synthetic lethality with Chs3p. cla4 and cdc11 mutants exhibited similar morphologic

11. Candida albicans Septin Mutants Are Defective for Invasive Growth and Virulence
Hyphal growth of Candida albicans is implicated as an important virulence factor for this opportunistic human pathogen. Septin proteins, a family of cytoskeletal elements that regulate membrane events and are important for proper morphogenesis of C. albicans, were examined for their role in tissue invasion and virulence in the mouse model of systemic infecti

12. MSF (MLL septin-like fusion), a fusion partner gene of MLL, in a therapy-related acute myeloid leukemia with a t(11;17)(q23;q25)
MLL (ALL1, Htrx, HRX), which is located on chromosome band 11q23, frequently is rearranged in patients with therapy-related acute myeloid leukemia who previously were treated with DNA topoisomerase II inhibitors. In this study, we have identified a fusion partner of MLL in a 10-year-old female who developed therapy-related acute myeloid leukemia 17 months af
