“PPM1D activity promotes genome instability and cellular transformation”
Protein phosphatase magnesium dependent 1 (PPM1D) is a negative regulator of the tumour suppressor p53 and is implicated in termination of DNA damage response. Increased PPM1D activity allows proliferation in the presence of DNA breaks caused by ionizing radiation or replication stress induced by expression of active RAS oncogene. Active PPM1D promotes cell growth in the soft agar and formation of tumours in nude mice confirming the oncogenic potential of PPM1D.
