CYK-4: A Rho family gtpase activating protein (GAP) required for central spindle formation and cytokinesis

During cytokinesis of animal cells, the mitotic spindle plays at least two roles. Initially, the spindle positions the contractile ring. Subsequently, the central spindle, which is composed of microtubule bundles that form during anaphase, promotes a late ...

Dissection of cell division processes in the one cell stage Caenorhabditis elegans embryo by mutational analysis

Pierre Gönczy

To identify novel components required for cell division processes in complex eukaryotes, we have undertaken an extensive mutational analysis in the one cell stage Caenorhabditis elegans embryo. The large size and optical properties of this cell permit obse ...

Puromycin-sensitive aminopeptidase: Sequence analysis, expression, and functional characterization

Daniel Constam

Among the molecular mechanisms that control the cell division cycle, proteolysis has emerged as a key regulatory process enabling cells to pass critical check points. Such proteolysis involves a cascade of enzymes including a multisubunit complex termed 26 ...

Local and Global Cytosolic Ca-2+ Oscillations Evoked by Agonists and Inositol Trisphosphate

Carl Petersen

The agonists acetylcholine (ACh) and cholecystokinin (CCK) evoke oscillating cytosolic Ca2+ signals in pancreatic acinar cells. Low agonist concentrations evoke local cytosolic Ca2+ spikes confined to the secretory pole region and intracellular inositol tr ...

Metaphase chromosome structure. Involvement of topoisomerase II.

Thierry Laroche

SCI is a prominent, 170,000 Mr, non-histone protein of HeLa metaphase chromosomes. This protein binds DNA and was previously identified as one of the major structural components of the residual scaffold structure obtained by differential protein extraction ...

"3-Fluorisopren" (2-Fluor-3-methyl-1,3-butadien) und einige heterosubstituierte Abkömmlinge

CH2:CFCMe:CHR (I, R = cyano, SO2Ph) were prepd. by ring cleavage of the cyclopropanes II (R = cyano, SO2Ph), prepd. by treating methallyl chloride with FCHCl3 and substitution in I (R = Cl). I (R = Bu, Ph) and Me3CCH:CHCMe:CF(CH2)4Me were obtained by treat ...

Silberion-induzierte Ringöffnung von Chlorofluorocyclopropanen

MeCR:CFCH2OH (R = Me, Pr, (CH2)3OAc) were prepd. in 53-60% yield by ring-cleavage of the cyclopropanes I with AgOAc-AgBF4 to give 50-64% MeCR:CFCH2OAc followed by hydrolysis. The isomeric acetates were easily sepd. by gas chromatog. [on SciFinder (R)] ...
