Abstract


Diverse steps in gene expression are tightly coupled. Curiously, the La-motif-containing protein Sro9 has been shown to play a role in transcription and translation. Here, we show that Sro9 interacts with nuclear and cytoplasmic protein complexes involved in gene expression. In addition, Sro9 shuttles between nucleus and cytoplasm and is exported from the nucleus in an mRNA export-dependent manner. Importantly, Sro9 is recruited to transcribed genes. However, whole genome expression analysis shows that loss of Sro9 function does not greatly change the level of specific transcripts indicating that Sro9 does not markedly affect their synthesis and/or stability. Taken together, Sro9 might bind to the mRNP already during transcription and accompany the mature mRNP to the cytoplasm where it modulates translation of the mRNA.
