    ..Thus, in addition to coordinating events during transcription (initiation, promoter clearance, and elongation), hPAF also coordinates events in RNA quality control. ..

    ..Our findings reveal that the SIN1-rictor-mTOR function in Akt-Ser473 phosphorylation is required for TORC2 function in cell survival but is dispensable for TORC1 function. ..

    ..We propose that vesicle fusion requires a specific interaction between the SM protein and the ternary SNARE complex. ..
  7. Tsang C, Li H, Zheng X. Nutrient starvation promotes condensin loading to maintain rDNA stability. EMBO J. 2007;26:448-58 pubmed
    ..Our data suggest that enrichment of condensin prevents rDNA instability during nutrient starvation. Together, these observations unravel a novel role for condensin in the maintenance of regional genomic stability. ..
  8. Chen C, Brill S. Binding and activation of DNA topoisomerase III by the Rmi1 subunit. J Biol Chem. 2007;282:28971-9 pubmed
    ..These results demonstrate that Top3-Rmi1 functions as a complex and suggest that Rmi1 stimulates Top3 by promoting its interaction with ssDNA. ..

    ..In contrast, deletion of RAD52 restores cell viability under the same conditions. These results reveal an opposing role of condensin and Rad52 in the control of rDNA stability under nutrient starvation conditions. ..

    ..Taken together, our results indicate a mechanism that separates the type I and type II receptors during receptor recycling, potentially terminating signaling while preserving both receptors for further rounds of activation. ..
