However, the question of whether the A14/A43 heterodimer is conserved in eukaryotes other than S. cerevisiae remains unanswered, although both Rpb4/Rpb7 and C17/C25 are conserved from yeast to human. To address this question, we have isolated a Schizosaccharomyces pombe gene named ker1+ using a yeast two-hybrid system, including rpa21+, which encodes an ortholog of A43, as bait. Although no homolog of A14 has previously been found in the S. pombe genome, functional characterization of Ker1p and alignment of Ker1p and A14 showed that Ker1p is an ortholog of A14. Disruption of ker1+ resulted in temperature-sensitive growth, and the temperature-sensitive deficit of ker1delta was suppressed by overexpression of either rpa21+ or rrn3+, which encodes the rDNA transcription factor Rrn3p, suggesting that Ker1p is involved in stabilizing the association of RPA21 and Rrn3p in pol I. We also found that Ker1p dissociated from pol I in post-log-phase cells, suggesting that Ker1p is involved in growth-dependent regulation of rDNA transcription."xsd:string |
