Enables RNA polymerase II cis-regulatory region sequence-specific DNA binding activity and protein kinase activity. Involved in cellular response to transforming growth factor beta stimulus; positive regulation of transcription by RNA polymerase II; and protein autophosphorylation. Predicted to be located in several cellular components, including Golgi-associated vesicle; cytosol; and nucleoplasm. Predicted to be active in Golgi apparatus. Orthologous to human STK16 (serine/threonine kinase 16). [provided by Alliance of Genome Resources, Apr 2022]
