Aurora A kinase regulates proper spindle positioning in C-elegans and in human cells

Pierre Gönczy, Coralie Busso, Sachin Kotak

Accurate spindle positioning is essential for error-free cell division. The one-cell Caenorhabditis elegans embryo has proven instrumental for dissecting mechanisms governing spindle positioning. Despite important progress, how the cortical forces that act ...

Discovery of a Selective Aurora A Kinase Inhibitor by Virtual Screening

Pierre Gönczy, Sachin Kotak, Maria Josefina Marcaida Lopez, Jean-Louis Reymond

Here we report the discovery of a selective inhibitor of Aurora A, a key regulator of cell division and potential anticancer target. We used the atom category extended ligand overlap score (xLOS), a 3D ligand-based virtual screening method recently develop ...

NuMA interacts with phosphoinositides and links the mitotic spindle with the plasma membrane

Pierre Gönczy, Coralie Busso, Sachin Kotak

The positioning and the elongation of the mitotic spindle must be carefully regulated. In human cells, the evolutionary conserved proteins LGN/Gai1-3 anchor the coiled-coil protein NuMA and dynein to the cell cortex during metaphase, thus ensuring proper s ...

NuMA phosphorylation by CDK1 couples mitotic progression with cortical dynein function

Pierre Gönczy, Coralie Busso, Sachin Kotak

Spindle positioning and spindle elongation are critical for proper cell division. In human cells, an evolutionary conserved ternary complex (NuMA/LGN/Gαi) anchors dynein at the cortex during metaphase, thus ensuring correct spindle positioning. Whether thi ...

Mechanisms of spindle positioning: cortical force generators in the limelight

Pierre Gönczy, Sachin Kotak

Correct positioning of the spindle governs placement of the cytokinesis furrow and thus plays a crucial role in the partitioning of fate determinants and the disposition of daughter cells in a tissue. Converging evidence indicates that spindle positioning ...

Cortical dynein is critical for proper spindle positioning in human cells

Pierre Gönczy, Coralie Busso, Sachin Kotak

Correct spindle positioning is fundamental for proper cell division during development and in stem cell lineages. Dynein and an evolutionarily conserved ternary complex (nuclear mitotic apparatus protein [NuMA]–LGN–Gα in human cells and LIN-5–GPR-1/2–Gα in ...
