Abstract
- Protein phosphorylation, regulated by protein kinases and protein phosphatases, is crucial for protein structure and function in eukaryotic organisms. Type 2C protein phosphatase (PP2C) belongs to the serine/threonine phosphatase family and its activities require the presence of a divalent magnesium or manganese ion. In the present study, a potential PP2C phosphatase (SjPtc1) was identified in Schistosoma japonicum . The SjPTC1 gene was found to be highly expressed in adult worms. A recombinant SjPtc1 protein showed typical PP2C phosphatase activity. Heterologous SjPTC1 expression reversed the sensitivity of yeast ptc1 null mutants toward H 2 O 2 , ZnCl 2 , cisplatin, and rapamycin. Collectively, the results suggest that SjPtc1 may take part in the regulation of cellular responses to oxidative stress, DNA damage stress, and the TOR (target of rapamycin) signaling pathway.
