Enables protein kinase binding activity; protein serine/threonine kinase activity; and tau-protein kinase activity. Involved in several processes, including microtubule cytoskeleton organization involved in establishment of planar polarity; regulation of axonogenesis; and regulation of insulin secretion involved in cellular response to glucose stimulus. Acts upstream of or within neuron projection morphogenesis and peptidyl-serine phosphorylation. Predicted to be located in distal axon and endoplasmic reticulum. Predicted to be active in centrosome and cytoplasm. Is expressed in several structures, including central nervous system and retina. Orthologous to human BRSK2 (BR serine/threonine kinase 2).
