Abstract

We have isolated Glel homologue (named as spglel) as a partial multicopy suppressor of the synthetic lethality of rael-167 elfl-21 in fission yeast Schizosaccharomyces pombe. The spglel is also able to complement partially temperature-sensitive phenotype of rael-167 only at a lower restrictive temperature. The spglel gene contains one intron and encodes a 480 amino-acid protein with predicted molecular weight of 56.2 kDa. We showed that spglel gene is essential for vegetative growth and functional Glel-GFP protein is localized mainly in NPC. The accumulation of poly(A)(+) RNA in the nucleus is exhibited when expression of spglel is repressed or over-expressed. These results suggest that the spGle1 protein is also involved in mRNA export in fission yeast.
