CIP2A (cancerous inhibitor of PP2A) was originally identified as p90, a cytoplasmic autoantigen found in the serum from a cancer patient. It was later described as a protein that interacted with the c-myc oncogene and functioned as an inhibitor of protein phosphatase 2A (PP2A) activity. Inhibition of PP2A phosphatase activity by CIP2A prevents c-myc phosphorylation and counteracts c-myc proteolytic degradation, thereby stabilizing c-myc and promoting cell growth and transformation. CIP2A is found to be over expressed in some human malignancies and is thus classified as an oncogene that may be an important contributor to tumor formation.

CIP2A - A lean, mean, oncoprotein machine The CIP2A protein was originally identified as p90, a cytoplasmic auto-antigen from the serum of a cancer patient. It was later found to inhibit protein phosphatase 2A (PP2A) activity as well as interact with c-myc. CIP2A's inhibitory activity blocks ... Read full blog post.
CIP2A: The Cancerous Inhibitor of Protein Phosphatase 2A The autoantigen p90 is a recently discovered protein that binds to and inhibits Protein Phosphatase 2A (PP2A) activity, thereby playing a critical role in cancer progression. Thus, p90 was renamed the "cancerous inhibitory protein of PP2A" or CIP2A.... Read full blog post.
