uvi31+ is a sequence homolog of Escherichia coli bolA gene in Schizosaccharomyces pombe, identified as a UV-inducible gene. Here, the cellular function of uvi31+ was investigated by null mutant analysis. Deletion of uvi31+ led to a delayed germination of spore and defects in subsequent cell division. However, the uvi31 mutant cell proliferated faster with smaller cell size than the wild-type cell during vegetative growth. In addition, the uvi31 mutant was sensitive to UV-light. It showed a normal cell cycle delay after UV-irradiation but displayed aberrant septum formation and defective cytokinesis when released from the UV damage checkpoint. These results suggest that uvi31+ may be involved in control of cell division, especially during the resumption from cell cycle arrest.
