Abstract
In A. nidulans, the temperature-sensitive cell cycle mutation bimC4 causes an elevated mitotic index at restrictive temperature. Under restrictive conditions the mutation interferes with separation of the spindle pole bodies, causes abnormal spindle morphology, and prevents nuclear division. We have cloned and sequenced the wild-type bimC gene. The predicted protein product has homology to Drosophila kinesin heavy chain. We conclude that this kinesin-like protein has an important role in nuclear division in Aspergillus.
