Dictyostelium discoideum: a promising centrosome model system

Abstract

The centrosome of the slime mould Dictyostelium discoideum displays a morphology markedly different from centriolar centrosomes or yeast spindle pole bodies, while fulfilling the same conserved functions in the organization of the microtubule cytoskeleton. Recent advances suggest that the Dictyostelium centrosome may offer an interesting model system, usefully complementing other well-studied centrosome models. The establishment of an isolation procedure and the generation of a range of monoclonal antibodies have been achieved, which are important pre-requisites for biochemical investigation. Furthermore, the role of the centrosome in cell motility and centrosome duplication process have been investigated using cells with GFP-labelled centrosomes.
