Predicted to enable protein serine/threonine kinase activity. Predicted to be involved in cytoskeleton organization; intracellular signal transduction; and peptidyl-serine phosphorylation. Predicted to act upstream of or within phosphorylation. Predicted to be located in cytoplasm. Is expressed in brain; thymus primordium; and ventral grey horn. Orthologous to human MAST4 (microtubule associated serine/threonine kinase family member 4). [provided by Alliance of Genome Resources, Apr 2022]
