CP and CDS conceived and designed the project and most of the experiments. CP performed most of the experiments. AM and AMB performed the experiments on cES cells and two-hybrid screens from cES cell cDNAs (these were conceived and designed by JS), and CP and SB designed and performed the two-hybrid screen experiments using chicken embryo cDNAs. YS and JCS perfected the use of Venus for BiFCO experiments. AM, AMB, YS, JCS, and JS contributed reagents/materials/analysis tools. CP and CDS wrote the paper.
