title: [Screening and detecting of proteins interaction with KyoT].
abstract: To study the function of KyoT2 in vivo, two-hybrid yeast, purification of KyoT2 protein, preparation of antibody and GST-pulldown methods were used in the experiments. 42 clones were obtained after 5 x 10(6) clones were screened by four kinds of nutrition limitation and beta-galactosidase assay, 22 clones were obtained after restriction of positive clones. Finally, 13 genes were obtained by sequence assay. Two of these were RBP-Jk and PIAS1. After they and KyoT2 changed vectors, negative two-hybrid yeast was finished. The result was positive; Using KyoT2 protein and antibody GST-pulldown of KyoT2 and RBP-Jk, KyoT2 and PIAS1 were done, the result was also positive. Therefore, KyoT2 interacted with RBP-Jk and PIAS1.
