It was reported that LIM protein KyoT2 negatively regulated transcription by association with the RBP-J DNA-binding protein. Using yeast two-hybrid system with LIM protein KyoT2 as a bait, we have isolated an alternatively spliced form of human tight junction protein 2--ZO-2-i3. Sequence analysis indicated that ZO-2-i3 is composed of 19 exons, and selected usage of exons led to an alteration in the region following the kinase domain as compared with the published sequence. To identify the interaction between LIM protein KyoT2 and ZO-2-i3, yeast two-hybrid system, purification of KyoT2 protein, and GST pull-down assay were performed in the experiments. After KyoT2 and ZO-2-i3 changed vectors, positive two-hybrid yeast was obtained. Using KyoT2 protein and antibody in GST pull-down assay positive result was also obtained. Therefore we conformed KyoT2 interacted ZO-2-i3 in vitro. Furthermore it was identified in yeast that KyoT2 associated with ZO-2-i3 through its LIM2 domain.
