Abstract
To screen Foxp3Delta2-interacting proteins by yeast two-hybria. pGBKT7-Foxp3Delta2 bait plasmid was constructed. Its toxicity and transcriptional activation in yeast cell AH109 was tested by observation of phenotypes and color. The bait plasmid pGBKT7-Foxp3Delta2 was constructed successfully and there was no self-activation or toxicity in AH109. Forty positive clones were obtained. After sequence comparison and analysis, nine candidate proteins were finally selected for further confirmation. Yeast two hybrid system could be used for screening Foxp3Delta2-interacting proteins. These results provide essential clues for further investigation of Foxp3Delta2 function.
