Predicted to enable MAP kinase kinase kinase activity. Predicted to be involved in several processes, including positive regulation of DNA metabolic process; positive regulation of p38MAPK cascade; and response to UV-C. Predicted to act upstream of or within several processes, including chorionic trophoblast cell differentiation; male germ-line sex determination; and positive regulation of JUN kinase activity. Predicted to be located in cytoplasm. Orthologous to human MAP3K4 (mitogen-activated protein kinase kinase kinase 4). [provided by Alliance of Genome Resources, Apr 2022]
