As a key cell cycle regulator, polo-like kinase 1 (Plk1) has been recognized as a crucial factor involved in the progression of pancreatic cancer (PC). However, its regulatory mechanism is poorly understood. Here, we present evidence that Plk1 is a novel substrate of vaccinia-related kinase 2 (VRK2), a serine-threonine kinase that is highly expressed and predicts poor prognosis in PC. VRK2 phosphorylates Plk1 at threonine 210 and protects it from ubiquitin-dependent proteasomal degradation. We showed that mechanistically complemen
