WitrynaAbstract. Microtubules are the ubiquitous components of eukaryotic cells and are organized around specific cellular structures referred as “microtubule-organizing centers” (MTOCs). This chapter describes the functional components of MTOCs. Three types of MTOCs are found in all cell types: (1) centrosome, or equivalent structure, … WitrynaMicrotubule patterning does not occur randomly, but is imparted by distinct subcellular sites called microtubule-organizing centers (MTOCs). Since the discovery of MTOCs …
Witryna24 sty 2024 · Although the role of F-actin in regulating these critical processes has been studied extensively, little is known about whether microtubules (MTs) participate in regulating these processes. Using mouse oocytes as a model system, we characterize a subset of MT organizing centers that do not contribute directly to spindle assembly, …
