Abstract
The sp%pl null mutant was constructed to study the function of fission yeast Schizosaccharomyces pombe spThp1, which is homologous to budding yeast Saccharomyces cerevisiae THP1. Tetrad analysis showed that the spThp1 is not essential for vegetative growth. The spThp1 null mutant also showed no massive poly(A)+ RNA export defect. However, spThp1 null is genetically associated with spMex67 null. These results suggest that spThp1 is involved in mRNA export out of the nucleus.
