Predicted to enable several functions, including IkappaB kinase complex binding activity; JUN kinase kinase kinase activity; and protein homodimerization activity. Predicted to be involved in several processes, including positive regulation of JUN kinase activity; positive regulation of cell projection organization; and protein phosphorylation. Predicted to be located in membrane. Orthologous to human MAP3K13 (mitogen-activated protein kinase kinase kinase 13). [provided by Alliance of Genome Resources, Apr 2022]
