Enables protein kinase activity. Acts upstream of or within several processes, including establishment of cell polarity; neuron projection morphogenesis; and peptidyl-tyrosine phosphorylation. Located in cytoplasm. Is expressed in several structures, including 8-cell stage embryo; alimentary system; blastocyst; brain ventricular layer; and inferior colliculus. Orthologous to human WEE1 (WEE1 G2 checkpoint kinase). [provided by Alliance of Genome Resources, Apr 2022]
