May act as a mediator of stress-activated signals. The phosphorylated form forms a complex with WNK2. Predominantly expressed in brain and pancreas followed by heart, lung, kidney, skeletal muscle, liver, placenta and testis. Belongs to the protein kinase superfamily. STE Ser/Thr protein kinase family. STE20 subfamily. Note: This description may include information from UniProtKB.
