Gravin is a transitory effector of polo-like kinase 1 during cell division.
The mitogenic and second-messenger signals that promote cell proliferation often proceed through multienzyme complexes. The kinase-anchoring protein Gravin integrates cAMP and calcium/phospholipid signals at the plasma membrane by sequestering protein kinases A and C with G protein-coupled receptors. In this report we define a role for Gravin as a temporal organizer of phosphorylation-dependent...
متن کاملAurora promotes cell division during recovery from TOR-mediated cell cycle arrest by driving spindle pole body recruitment of Polo.
The coordination of cell division and growth in response to changes in nutrient supply is mediated by TOR signalling. In fission yeast, increased nutrient provision transiently delays mitotic onset without affecting growth. The result is an increase in cell size at division. We find that this block to cell division relies upon TOR and MAPK signalling and that mitotic entry during recovery from ...
متن کاملBorrelia burgdorferi ftsZ plays a role in cell division.
ftsZ is essential for cell division in many microorganisms. In Escherichia coli and Bacillus subtilis, FtsZ plays a role in ring formation at the leading edge of the cell division septum. An ftsZ homologue is present in the Borrelia burgdorferi genome (ftsZ(Bbu)). Its gene product (FtsZ(Bbu)) is strongly homologous to other bacterial FtsZ proteins, but its function has not been established. Bec...
متن کاملSgt1, a co-chaperone of Hsp90 stabilizes Polo and is required for centrosome organization.
Sgt1 was described previously in yeast and humans to be a Hsp90 co-chaperone and required for kinetochore assembly. We have identified a mutant allele of Sgt1 in Drosophila and characterized its function. Mutations in sgt1 do not affect overall kinetochore assembly or spindle assembly checkpoint. sgt1 mutant cells enter less frequently into mitosis and arrest in a prometaphase-like state. Mutat...
