Cyclin B is associated with centrosomes in Drosophila mitotic cells

Abstract:
We have studied by way of confocal laser scanning microscopy the subcellular localization of cyclin B in Drosophila-cultured cells and report here evidence that a part of the cyclin B cell pool is closely associated with the centrosome. This cyclin B centrosomal signal is strong in prophase and metaphase but disappears during anaphase. Moreover, the signal is absent in the acentriolar Drosophila cell line 1182-4. These results put forward additional arguments suggesting that the centrosome plays an important role in the control of the cell cycle.
