hSiah2 is a new vav binding protein which inhibits Vav-mediated signaling pathways
The hematopoietic proto-oncogene vav has been characterized as a Rac1- GDP/GTP exchanger protein which regulates cytoskeletal reorganization as well as signaling pathways leading to the activation of stress-activated protein ...
Securin Is a Target of the UV Response Pathway in Mammalian Cells
All eukaryotic cells possess elaborate mechanisms to protect genome integrity and ensure survival after DNA damage, ceasing proliferation and granting time for DNA repair. Securin is an inhibitory protein that is bound to ...
Genetic and biochemical study of threonine-overproducing mutants of Saccharomyces cerevisiae
Three threonine-overproducing mutants were obtained as prototrophic revertants of a hom3 mutant strain of Saccharomyces cerevisiae. The gene HOM3 codes for aspartokinase (aspartate kinase; EC 220.127.116.11), the first enzyme of ...
Accumulation of Poly(beta-Hydroxybutyrate) by Halobacteria
(American Society for Microbiology, 1986)
Some species of extremely halophilic archaebacteria, Halobacteriaceae, have been shown to accumulate large amounts of poly(P-hydroxybutyrate) under conditions of nitrogen limitation and abundant carbon source. The production ...
βTrCP controls the lysosome-mediated degradation of CDK1, whose accumulation correlates with tumor malignancy
(Impact Journals, 2014)
n mammals, cell cycle progression is controlled by cyclin-dependent kinases, among which CDK1 plays important roles in the regulation of the G2/M transition, G1 progression and G1/S transition. CDK1 is highly regulated by ...
Cortical development associated with conjugation of Paramecium
(Company of Biologists Ltd, 1993-03)
The cortical cytoskeleton of Paramecium is characterized by a complex, polarized and asymmetrical organization. In order to analyse the cortical development of Paramecium tetraurelia during the sexual process of conjugation, ...
EhLimA, a novel LIM protein, localizes to the plasma membrane in Entamoeba histolytica
(American Society for Microbiology, 2007-09)
The parasitic protozoan Entamoeba histolytica relies on a very dynamic cytoskeleton in order to invade and survive in host tissues. Identification of cytoskeletal elements is key to understanding these processes. Here we ...
Cysteine Proteases and Cell Differentiation: Excystment of the Ciliated Protist Sterkiella histriomuscorum
(American Society for Microbiology, 2003-12)
The process of excystment of Sterkiella histriomuscorum (Ciliophora, Oxytrichidae) leads in a few hours, through a massive influx of water and the resorption of the cyst wall, from an undifferentiated resting cyst to a ...
A Set of Lotus japonicus Gifu × Lotus burttii Recombinant Inbred Lines Facilitates Map-based Cloning and QTL Mapping
(Oxford University Press, 2012)
Model legumes such as Lotus japonicus have contributed significantly to the understanding of symbiotic nitrogen fixation. This insight is mainly a result of forward genetic screens followed by map-based cloning to identify ...
