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. Estudos estruturais e bioquímicos das septinas 7 e 9 humanas / Structural and biochemical studies of human septins 7 e 9
As proteínas pertencentes à família das septinas foram originalmente descobertas em 1971 em decorrencia de estudos genéticos em células mutantes. Essas proteínas encontradas em fungos e animais, mas não em plantas apresentam como principais características a presença de um domínio conservado de ligação aos nucleotídeos de guanina (GTP) e a forma

3. 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

4. p250GAP, a Novel Brain-enriched GTPase-activating Protein for Rho Family GTPases, Is Involved in the N-Methyl-d-aspartate Receptor Signaling
N-Methyl-d-aspartate (NMDA) receptors regulate structural plasticity by modulating actin organization within dendritic spines. Herein, we report identification and characterization of p250GAP, a novel GTPase-activating protein for Rho family proteins that interacts with the GluRε2 (NR2B) subunit of NMDA receptors in vivo. The p250GAP mRNA was enriched

5. Biological and structural characterization of a Ras transforming mutation at the phenylalanine-156 residue, which is conserved in all members of the Ras superfamily.
Although Ras residue phenylalanine-156 (F156) is strictly conserved in all members of the Ras superfamily of proteins, it is located outside of the consensus GDP/GTP-binding pocket. Its location within the hydrophobic core of Ras suggests that its strict conservation reflects a crucial role in structural stability. However, mutation of the equivalent residue

6. Expression, purification, and characterization of a novel G protein, SGP, from Streptococcus mutans.
The sgp gene of Streptococcus mutans was recently detected immediately downstream from the dgk gene within the same operon. In this study, the sgp gene was subcloned into the pMAL-c2 vector and SGP (S. mutans G protein) was overexpressed in Escherichia coli as a fusion protein with the maltose-binding protein at a level of 40% of total cellular protein.
