Polo-like kinase 3 (Drosophila), also known as PLK3, is an enzyme which in humans is encoded by the PLK3 gene.^[5][6]

Function

Cytokine-inducible kinase is a putative serine/threonine kinase. CNK contains both a catalytic domain and a putative regulatory domain. It may play a role in regulation of cell cycle progression and tumorigenesis.^[5]

Interactions

PLK3 has been shown to interact with:

• CDC25C,^[7]
• CHEK2,^[8] and
• P53.^[8][9]
