Abstract:The centrosome is the main microtubule organizing center (MTOC) in animal cells. It consists of a pair of centrioles surrounded by pericentriolar material (PCM) that nucleates and anchors microtubules. The binding of PCM to centrioles, PCM self-assembly and PCM transport by the microtubule-based motor dynein are the prerequisites for centrosome assembly, but the mechanisms of PCM self-assembly in interphase cells are poorly understood. Moreover, the relative importance of different molecular pathways of PCM as… Show more
