Abstract:

Caliban is a tumor suppressor. To understand its inherent mechanisms, we screened Caliban interacting proteins using the yeast two-hybrid system. We found four new Caliban interacting proteins, Bip2, Uba2, RpS27A, and CG7182. Moreover, over-expression of transcriptional factor Bip2 suppresses transcription of p 53. The tumor suppression function of p53 could be regulated through new mechanisms involving Bip2 and Caliban.

Key words: tumor suppressor, Caliban, yeast two hybrid, Bip2
