- Seeger M, Hartmann Petersen R, Wilkinson C, Wallace M, Samejima I, Taylor M, et al. Interaction of the anaphase-promoting complex/cyclosome and proteasome protein complexes with multiubiquitin chain-binding proteins. J Biol Chem. 2003;278:16791-6 pubmed..We show that both proteins bind to different regions of the proteasome subunit Mts4. The binding site for Pus1 was mapped to a cluster of repetitive sequences also found in the proteasome subunit ..

EMBO J. 1998;17:6465-76 pubmed..Furthermore they raise interesting questions as to the spatial organization of protein degradation during meiosis. ..
- Dunand Sauthier I, Walker C, Wilkinson C, Gordon C, Crane R, Norbury C, et al. Sum1, a component of the fission yeast eIF3 translation initiation complex, is rapidly relocalized during environmental stress and interacts with components of the 26S proteasome. Mol Biol Cell. 2002;13:1626-40 pubmed..Furthermore, Sum1 interacts with the Mts2 and Mts4 components of the 26S proteasome...
- Wilkinson C, Ferrell K, Penney M, Wallace M, Dubiel W, Gordon C. Analysis of a gene encoding Rpn10 of the fission yeast proteasome reveals that the polyubiquitin-binding site of this subunit is essential when Rpn12/Mts3 activity is compromised. J Biol Chem. 2000;275:15182-92 pubmed..lethal with mutations in other proteasomal component-encoding genes, namely mts3, pad1, and mts4 (RPN12, RPN11, and RPN1)...

PLoS ONE. 2010;5:e11371 pubmed publisher..The Vpr-proteasome interaction was initially discovered in fission yeast, where Vpr was shown to associate with Mts4 and Mts2, two 19S-associated proteins...

- Selvanathan S, Thakurta A, Dhakshnamoorthy J, Zhou M, Veenstra T, Dhar R. Schizosaccharomyces pombe Dss1p is a DNA damage checkpoint protein that recruits Rad24p, Cdc25p, and Rae1p to DNA double-strand breaks. J Biol Chem. 2010;285:14122-33 pubmed publisher..We suggest that the sequestration of Cdc25p to DNA damage sites could provide a mechanism for S. pombe cells to arrest at G(2)/M boundary in response to DNA damage. ..

- Cabrera R, Sha Z, Vadakkan T, Otero J, Kriegenburg F, Hartmann Petersen R, et al. Proteasome nuclear import mediated by Arc3 can influence efficient DNA damage repair and mitosis in Schizosaccharomyces pombe. Mol Biol Cell. 2010;21:3125-36 pubmed publisher..These data suggest that proteasomes display Arc3-dependent mobility in the cell, and mobile proteasomes can efficiently access substrates throughout the cell, allowing them to effectively regulate cell-compartment-specific activities. ..
- Penney M, Wilkinson C, Wallace M, Javerzat J, Ferrell K, Seeger M, et al. The Pad1+ gene encodes a subunit of the 26 S proteasome in fission yeast. J Biol Chem. 1998;273:23938-45 pubmed..This screen has previously isolated mutations in the 26 S proteasome subunits Mts2, Mts3, and Mts4. We show that the mutation in the mts5-1 strain occurs in the pad1(+) gene...
