The pericentriolar material

WebbProteins in the pericentriolar material stimulate the production of tubulin proteins. γ-tubulin located in the pericentriolar material is arranged in a ring-like complex that mimics the + polarized end, giving the – end of microtubules a site to bond to. Centrosomes play a … Webb29 sep. 2024 · Abstract. During mitosis in animal cells, the centrosome acts as a microtubule organizing center (MTOC) to assemble the mitotic spindle. MTOC function at the centrosome is driven by proteins within the pericentriolar material (PCM), however the molecular complexity of the PCM makes it difficult to differentiate the proteins required …

WebbWe show that RNA interference-mediated Aurora-A inactivation causes pericentriolar material fragmentation in prometaphase, yielding the formation of spindles with supernumerary poles. This fragmentation does not necessarily involve centrioles and requires microtubules (MTs).
