Cancerous inhibitor of protein phosphatase 2A (CIP2A) is a characterized human oncoprotein that is able to promote cancer cells proliferation, anchorage-independent cell growth and resistance to apoptosis. CIP2A inactivates protein phosphatase 2A (PP2A) which down-regulates Akt (Protein Kinase B) phosphorylation and stabilizes c-Myc (c-Myc oncogene product) in cancer cells. CIP2A has been studied in the most of human malignancies.[1]
