Inactive kinase that suppresses ERK activity by promoting phosphatase activity of DUSP3 which specifically dephosphorylates and inactivates ERK in the nucleus. Belongs to the protein kinase superfamily. CK1 Ser/Thr protein kinase family. VRK subfamily. 2 human isoforms produced by alternative splicing. Note: This description may include information from UniProtKB.
