Survivin is a small protein which plays an important role in cell proliferation and cell division because survivin is a component of chromosomal passenger complex including Aurora kinase B. Cyclin D1,TP53, CDK4 and Aurora kinase are all involved in survivin networks at cell division. Survivin is also an inhibitor of apoptosis. STAT3, PI3K, BAX, AIP, NF-κB, Bcl-2, and P38 MAPK are all involved in the survivin anti-apoptotic network. Now survivin is a prognostic marker for cancer, and a target for chemotherapy.
