Predicted to enable protein serine/threonine kinase activity. Involved in several processes, including microtubule cytoskeleton organization; negative regulation of metaphase/anaphase transition of meiotic cell cycle; and positive regulation of MAPK cascade. Acts upstream of or within regulation of meiotic nuclear division. Located in cytoplasm. Is expressed in brain; early conceptus; gonad; large intestine; and metanephros. Orthologous to human MOS (MOS proto-oncogene, serine/threonine kinase). [provided by Alliance of Genome Resources, Apr 2022]
