Abstract |
Sus1 / ENY2 is a tiny conserved protein that is involved in
chromatin remodeling and mRNA biogenesis. Sus1 is associated
to two nuclear complexes, the transcriptional coactivator SAGA
and the nuclear pore associated TREX2. In fission yeast,
Schizosaccharomyces pombe, ortholog of Sus1 / ENY2 was
identified from the genome database. Tetrad analysis showed
that the S. pombe sus1 is not essential for growth. However,
deletion of the sus1 gene caused cold-sensitive growth retardation
with slight accumulation of poly(A)+ RNA in the nucleus. And
the Sus1-GFP protein is localized mainly in the nucleus. Yeast
two-hybrid analysis and co-immunoprecipitation experiment
showed that Sus1 interacts with Sac3, another subunit of TREX2
complex. These results suggest that S. pombe Sus1 is also
involved in mRNA export from the nucleus as a component of
TREX-2 complex. |
