Popis: In this study we have cloned a novel member of mouse protein phosphatase 2C family, PP2Cζ, which is composed of 507 amino acids and has a unique N-terminal region. The overall similarity of the amino acid sequence between PP2Cζ and PP2Cα was 22%. On Northern blot analysis PP2Cζ was found to be expressed specifically in the testicular germ cells. PP2Cζ expressed in COS7 cells was able to associate with ubiquitin conjugating enzyme 9 (UBC9) and the association was enhanced by co-expression of small ubiquitin-related modifier-1 (SUMO-1), suggesting that PP2Cζ exhibits its specific role through its SUMO-induced recruitment to UBC9.
