Osteopontin localizes to the nucleus of 293 cells and associates with polo-like kinase-1.

American journal of physiology. Cell physiology - 1 Feb 2007

Abstract excerpt

Osteopontin (OPN) is a secreted phosphoprotein involved in cellular proliferation and associated with tumor progression. Although an intracellular form of OPN has been described, its function remains unknown. In this study, a novel nuclear location for intracellular OPN and a correlation with cel...
