Enables protein serine/threonine kinase activity. Predicted to be involved in several processes, including cellular protein metabolic process; cytoskeleton organization; and intracellular signal transduction. Predicted to act upstream of or within neuron projection morphogenesis and peptidyl-serine phosphorylation. Located in distal axon. Orthologous to human BRSK2 (BR serine/threonine kinase 2).
