General description

Protein CIP2A (UniProt: Q8TCG1; also known as CIP2A, Cancerous inhibitor of PP2A, p90 autoantigen) is encoded by the KIAA1524 (also known as CIP2A) gene (Gene ID: 57650) in human. CIP2A is a single pass membrane protein that exhibits dynamic changes in localization, including the cytoplasm and centrosome, depending on the stage of the cell cycle. It is expressed at low levels in most tissues, however, it is overexpressed in several cancers, including head-and-neck squamous cell carcinomas and liver cancer cells. Levels of CIP2A are correlated with the proliferation of human cancer cells and with cancer progression. It acts as an oncoprotein and inhibits protein phosphatase 2A activity and thereby stabilizes c-Myc in human malignancies. It promotes anchorage-independent cell growth and tumor formation. Higher activity of c-Myc rapidly induces the activation of cyclin E-cdk2 kinase activity. Concurrently, the release of p27Kip1 from Cdk2 complexes enhances cell proliferation. In CIP2A depleted cells, centrosome separation and the mitotic spindle dynamics were impaired, which leads to the activation of spindle assembly checkpoint signaling and, ultimately, delayed cell division time. CIP2A is also reported to interact with NIMA (never in mitosis gene A)-related kinase 2 (NEK2) during G2/M phase and enhances NEK2 kinase activity that facilitates centrosome separation in a PP1- and PP2A-independent manner.
