Enables protein serine/threonine kinase activity. Involved in several processes, including cellular hypotonic response; chemokine (C-C motif) ligand 21 signaling pathway; and positive regulation of T cell chemotaxis. Predicted to be located in cytosol. Is expressed in loop of Henle distal straight tubule and metanephros. Orthologous to human OXSR1 (oxidative stress responsive kinase 1).
