Regulation of the centrosome cycle
The centrosome, consisting of mother and daughter centrioles surrounded by the pericentriolar matrix (PCM), functions primarily as a microtubule organizing center (MTOC) in most animal cells. In dividing cells the centrosome duplicates once per cell cycle and its number and structure are highly regulated during each cell cycle to organize an effective bipolar spindle in the mitotic phase. Defec...
متن کاملRegulation of the cell cycle and centrosome biology by deubiquitylases
Post-translational modification of proteins by ubiquitylation is increasingly recognised as a highly complex code that contributes to the regulation of diverse cellular processes. In humans, a family of almost 100 deubiquitylase enzymes (DUBs) are assigned to six subfamilies and many of these DUBs can remove ubiquitin from proteins to reverse signals. Roles for individual DUBs have been delinea...
متن کاملCell cycle: Driving the centrosome cycle
Cyclin-dependent kinases (Cdks) control major transitions as cells pass through the cell cycle. It has recently been shown that centrosome duplication in vertebrates requires Cdk2 activity and can be driven solely by Cdk2-cyclin E complexes.
متن کاملCentrosome control of the cell cycle.
Early observations of centrosomes, made a century ago, revealed a tiny dark structure surrounded by a radial array of cytoplasmic fibers. We now know that the fibers are microtubules and that the dark organelles are centrosomes that mediate functions far beyond the more conventional role of microtubule organization. More recent evidence demonstrates that the centrosome serves as a scaffold for ...
