- The nucleolus: an old factory with unexpected capabilitiesM O Olson
Dept of Biochemistry, The University of Mississippi Medical Center, Jackson, MS 39216 4505, USA
Trends Cell Biol 10:189-96. 2000..Unexpectedly, the nucleolus also seems to play a role in nuclear export, sequestering regulatory molecules, modifying small RNAs, assembling ribonucleoprotein (RNP) and controlling aging...
- Sensing cellular stress: another new function for the nucleolus?Mark O J Olson
Department of Biochemistry, University of Mississippi Medical Center, 2500 North State Street, Jackson, MS 39216, USA
Sci STKE 2004:pe10. 2004..These factors, especially ARF (alternative reading frame), inhibit the degradation of p53, thereby facilitating its intracellular accumulation...
- Protein NPM3 interacts with the multifunctional nucleolar protein B23/nucleophosmin and inhibits ribosome biogenesisNian Huang
Department of Biochemistry, University of Mississippi Medical Center, Jackson, MI 39216, USA
J Biol Chem 280:5496-502. 2005..Overexpression of a mutant of NPM3 that did not interact with B23 did not alter pre-rRNA synthesis and processing, suggesting that the interaction of NPM3 with B23 plays a role in the ribosome biogenesis...
- Effects of interphase and mitotic phosphorylation on the mobility and location of nucleolar protein B23Sandeep S Negi
Department of Biochemistry, University of Mississippi Medical Center, Jackson, MS 39216, USA
J Cell Sci 119:3676-85. 2006..1, the longer variant. These results provide evidence that phosphorylation at these sites reduces the affinity of B23 for nucleolar components and might be a factor in regulating its location during the cell cycle...

Department of Biochemistry, University of Mississippi Medical Center, Jackson 39216, USA
Int Rev Cytol 219:199-266. 2002..Additional progress in defining the mechanisms of each step in ribosome biogenesis as well as clarification of the precise role of the nucleolus in nonconventional activities is expected in the next decade...
- Role of protein kinase CK2 phosphorylation in the molecular chaperone activity of nucleolar protein b23Attila Szebeni
Department of Biochemistry, University of Mississippi Medical Center, Jackson, Mississippi 39216, USA
J Biol Chem 278:9107-15. 2003..These studies suggest that unlike many molecular chaperones, which directly hydrolyze ATP, substrate release by protein B23 is dependent on its phosphorylation by CK2...
