The spindle pole body of is asymmetrical and contains changing numbers of γ-tubulin complexes.

Centrosomes are important microtubule-organizing centers (MTOCs) in animal cells. In addition, non-centrosomal MTOCs (ncMTOCs) are found in many cell types. Their composition and structure are only poorly understood.

Microtubule-organizing centers of Aspergillus nidulans are anchored at septa by a disordered protein.

Microtubule-organizing centers (MTOCs) are large, multi-subunit protein complexes. Schizosaccharomyces pombe harbors MTOCs at spindle pole bodies, transient MTOCs in the division plane (eMTOCs) and nuclear-envelope associated MTOCs in interphase cells (iMTOCs). In the filamentous fungus Aspergillus nidulans SPBs and septum-associated MTOCs were described.
