摘要
Objective: To study the disruption of co- localization of human Daxx(hDaxx) with promyelocytic leukemia protein(PML) at the PML oncogenic domains (PODs) by the interaction of hDaxx with adenovirus(Ad) 12 E1B 55 Kilodalton Oncoprotein (Ad12 E1B 55kD). Methods: The direct binding reaction of hDaxx and Ad12 E1B 55kD was analyzed by coimmunoprecipitation and Western blotting in vivo or in vitro. The interaction of hDaxx with Ad12 E1B 55kD was studied using yeast two-hybrid assay. Results: hDaxx bounded directly to Ad12 E1B 55kD in vivo and in vitro. hDaxx interacted with full length Ad12 E1B 55kD. Conclusion: Transcriptional regulator hDaxx directly binds to and interacts with Ad12 E1B 55kD.
