Background: Plk1 is a serine/threonine kinase and one of the polo-like kinase family members. The mammalian family of polo-like kinases consists of at least five described members, polo-like kinases 1–5 (Plk1-5), which are central regulator of cell division required for several events of mitosis and cytokinesis. The expression of Plk1 begins to increase from S/G2 phase, and its activity peaks at mitosis. The kinase is involved in centrosome maturation, kinetochore-microtubule attachment, bipolar spindle formation and cytokinesis. Deregulated expression of Plk1 accelerates cell division abnormally and promotes tumorigenesis. Plk1 is composed of two functional domains; one is the kinase domain and a polo-box domain on C-terminal for targeting of substrate and involving in its subcellular localization.
