Yeast 2-hybrid project has switched to a macrophage focus • Years 1 and 2 (to May ‘03) • Baits screened against 3 libraries (all mouse): • Primary B cell + WEHI231 B cell line • Primary myocyte* • NK tag myocyte cell line • Year 3 (May ‘03-’04) • New macrophage library prepared • Resting RAW cells • LPS + IFNg stimulated RAW cells • Primary bone marrow-derived macrophages • Year 3 baits are currently being screened against 3 libraries • Macrophage • B cell • Mouse embryo (mixture of several embryonic stages)
Current status of Y2H screens • New macrophage library ready for use late 2003 • 74 bait proteins selected for screening this year • 46 new proteins • 28 proteins previously screened against old library set selected for re-screening • See poster #07 for full bait list • Data pending on this years screens • Completion of screens from years 1 and 2 has provided a large quantity of new data • May 2003 473 interactions • May 2004 1081 interactions
AfCS proteins in FXM pathway Other AfCS proteins Protein with no AfCS ID (GI# known) Protein with no AfCS ID (novel sequence) All 1081 interactions viewed in cytoscape
Yeast 2-Hybrid summary • Website and data format improvements significantly enhance utility of Y2H data • We expect the current ‘year 3’ screens to provide valuable additional data, especially for proteins central to macrophage signaling pathways • Prevalence of FXM specific proteins in this years bait set should provide a wealth of protein-protein interaction data for this network
