    Beschreibung: We have developed an approach using Bayesian networks to predict protein-protein interactions genome-wide in yeast. Our method naturally weights and combines into reliable predictions genomic features only weakly associated with interaction (e.g., messenger RNAcoexpression, coessentiality, and colocalization). In addition to de novo predictions, it can integrate often noisy, experimental interaction data sets. We observe that at given levels of sensitivity, our predictions are more accurate than the existing high-throughput experimental data sets. We validate our predictions with TAP (tandem affinity purification) tagging experiments. Our analysis, which gives a comprehensive view of yeast interactions, is available at genecensus.org/intint.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jansen, Ronald -- Yu, Haiyuan -- Greenbaum, Dov -- Kluger, Yuval -- Krogan, Nevan J -- Chung, Sambath -- Emili, Andrew -- Snyder, Michael -- Greenblatt, Jack F -- Gerstein, Mark -- New York, N.Y. -- Science. 2003 Oct 17;302(5644):449-53.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biophysics and Biochemistry, Yale University, 266 Whitney Avenue, Post Office Box 208114, New Haven, CT 06520, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14564010" target="_blank"〉PubMed〈/a〉

    Beschreibung: Human immunodeficiency virus (HIV) has a small genome and therefore relies heavily on the host cellular machinery to replicate. Identifying which host proteins and complexes come into physical contact with the viral proteins is crucial for a comprehensive understanding of how HIV rewires the host's cellular machinery during the course of infection. Here we report the use of affinity tagging and purification mass spectrometry to determine systematically the physical interactions of all 18 HIV-1 proteins and polyproteins with host proteins in two different human cell lines (HEK293 and Jurkat). Using a quantitative scoring system that we call MiST, we identified with high confidence 497 HIV-human protein-protein interactions involving 435 individual human proteins, with approximately 40% of the interactions being identified in both cell types. We found that the host proteins hijacked by HIV, especially those found interacting in both cell types, are highly conserved across primates. We uncovered a number of host complexes targeted by viral proteins, including the finding that HIV protease cleaves eIF3d, a subunit of eukaryotic translation initiation factor 3. This host protein is one of eleven identified in this analysis that act to inhibit HIV replication. This data set facilitates a more comprehensive and detailed understanding of how the host machinery is manipulated during the course of HIV infection.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3310911/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3310911/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jager, Stefanie -- Cimermancic, Peter -- Gulbahce, Natali -- Johnson, Jeffrey R -- McGovern, Kathryn E -- Clarke, Starlynn C -- Shales, Michael -- Mercenne, Gaelle -- Pache, Lars -- Li, Kathy -- Hernandez, Hilda -- Jang, Gwendolyn M -- Roth, Shoshannah L -- Akiva, Eyal -- Marlett, John -- Stephens, Melanie -- D'Orso, Ivan -- Fernandes, Jason -- Fahey, Marie -- Mahon, Cathal -- O'Donoghue, Anthony J -- Todorovic, Aleksandar -- Morris, John H -- Maltby, David A -- Alber, Tom -- Cagney, Gerard -- Bushman, Frederic D -- Young, John A -- Chanda, Sumit K -- Sundquist, Wesley I -- Kortemme, Tanja -- Hernandez, Ryan D -- Craik, Charles S -- Burlingame, Alma -- Sali, Andrej -- Frankel, Alan D -- Krogan, Nevan J -- P01 AI090935/AI/NIAID NIH HHS/ -- P01 AI090935-02/AI/NIAID NIH HHS/ -- P01 GM073732-05/GM/NIGMS NIH HHS/ -- P41 GM103481/GM/NIGMS NIH HHS/ -- P41 RR001081/RR/NCRR NIH HHS/ -- P41RR001614/RR/NCRR NIH HHS/ -- P50 GM081879/GM/NIGMS NIH HHS/ -- P50 GM081879-02/GM/NIGMS NIH HHS/ -- P50 GM082250/GM/NIGMS NIH HHS/ -- P50 GM082250-05/GM/NIGMS NIH HHS/ -- P50GM081879/GM/NIGMS NIH HHS/ -- P50GM082545/GM/NIGMS NIH HHS/ -- U54 RR022220/RR/NCRR NIH HHS/ -- England -- Nature. 2011 Dec 21;481(7381):365-70. doi: 10.1038/nature10719.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cellular and Molecular Pharmacology, University of California, San Francisco, California 94158, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22190034" target="_blank"〉PubMed〈/a〉

    Beschreibung: Restriction factors, such as the retroviral complementary DNA deaminase APOBEC3G, are cellular proteins that dominantly block virus replication. The AIDS virus, human immunodeficiency virus type 1 (HIV-1), produces the accessory factor Vif, which counteracts the host's antiviral defence by hijacking a ubiquitin ligase complex, containing CUL5, ELOC, ELOB and a RING-box protein, and targeting APOBEC3G for degradation. Here we reveal, using an affinity tag/purification mass spectrometry approach, that Vif additionally recruits the transcription cofactor CBF-beta to this ubiquitin ligase complex. CBF-beta, which normally functions in concert with RUNX DNA binding proteins, allows the reconstitution of a recombinant six-protein assembly that elicits specific polyubiquitination activity with APOBEC3G, but not the related deaminase APOBEC3A. Using RNA knockdown and genetic complementation studies, we also demonstrate that CBF-beta is required for Vif-mediated degradation of APOBEC3G and therefore for preserving HIV-1 infectivity. Finally, simian immunodeficiency virus (SIV) Vif also binds to and requires CBF-beta to degrade rhesus macaque APOBEC3G, indicating functional conservation. Methods of disrupting the CBF-beta-Vif interaction might enable HIV-1 restriction and provide a supplement to current antiviral therapies that primarily target viral proteins.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3310910/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3310910/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jager, Stefanie -- Kim, Dong Young -- Hultquist, Judd F -- Shindo, Keisuke -- LaRue, Rebecca S -- Kwon, Eunju -- Li, Ming -- Anderson, Brett D -- Yen, Linda -- Stanley, David -- Mahon, Cathal -- Kane, Joshua -- Franks-Skiba, Kathy -- Cimermancic, Peter -- Burlingame, Alma -- Sali, Andrej -- Craik, Charles S -- Harris, Reuben S -- Gross, John D -- Krogan, Nevan J -- P01 AI090935/AI/NIAID NIH HHS/ -- P01 GM091743/GM/NIGMS NIH HHS/ -- P41 GM103481/GM/NIGMS NIH HHS/ -- P41RR001614/RR/NCRR NIH HHS/ -- P50 GM081879/GM/NIGMS NIH HHS/ -- P50 GM082250/GM/NIGMS NIH HHS/ -- P50 GM082250-05/GM/NIGMS NIH HHS/ -- P50GM081879/GM/NIGMS NIH HHS/ -- R01 AI064046/AI/NIAID NIH HHS/ -- T32 AI083196/AI/NIAID NIH HHS/ -- U54 RR022220/RR/NCRR NIH HHS/ -- England -- Nature. 2011 Dec 21;481(7381):371-5. doi: 10.1038/nature10693.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cellular and Molecular Pharmacology, University of California-San Francisco, San Francisco, California 94158, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22190037" target="_blank"〉PubMed〈/a〉

    Beschreibung: An epistasis map (E-MAP) was constructed in the fission yeast, Schizosaccharomyces pombe, by systematically measuring the phenotypes associated with pairs of mutations. This high-density, quantitative genetic interaction map focused on various aspects of chromosome function, including transcription regulation and DNA repair/replication. The E-MAP uncovered a previously unidentified component of the RNA interference (RNAi) machinery (rsh1) and linked the RNAi pathway to several other biological processes. Comparison of the S. pombe E-MAP to an analogous genetic map from the budding yeast revealed that, whereas negative interactions were conserved between genes involved in similar biological processes, positive interactions and overall genetic profiles between pairs of genes coding for physically associated proteins were even more conserved. Hence, conservation occurs at the level of the functional module (protein complex), but the genetic cross talk between modules can differ substantially.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2753251/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2753251/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Roguev, Assen -- Bandyopadhyay, Sourav -- Zofall, Martin -- Zhang, Ke -- Fischer, Tamas -- Collins, Sean R -- Qu, Hongjing -- Shales, Michael -- Park, Han-Oh -- Hayles, Jacqueline -- Hoe, Kwang-Lae -- Kim, Dong-Uk -- Ideker, Trey -- Grewal, Shiv I -- Weissman, Jonathan S -- Krogan, Nevan J -- GM084279/GM/NIGMS NIH HHS/ -- R01 GM084279/GM/NIGMS NIH HHS/ -- R01 GM084279-01A1/GM/NIGMS NIH HHS/ -- R01 GM084279-02/GM/NIGMS NIH HHS/ -- R01 GM084279-02S1/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Oct 17;322(5900):405-10. doi: 10.1126/science.1162609.
