Overview:

PLK3 or Polo-like kinase 3 is a cytokine-inducible kinase that is a member of the Polo family of serine/threonine protein kinases. PLK3 contains both a catalytic domain and a putative regulatory domain and plays an important role in the regulation of cell cycle progression and tumorigenesis (1). PLK3 is closely associated with centrosomes in several human cell lines and its localization is dependent on the integrity of microtubules. Hence, PLK3 is also involved in regulating microtubule dynamics and centrosomal function (2).
