Predicted to enable MAP kinase kinase activity and protein kinase binding activity. Involved in several processes, including cellular response to sorbitol; positive regulation of macromolecule metabolic process; and response to ischemia. Located in cytosol. Used to study retinal disease. Human ortholog(s) of this gene implicated in cervical cancer and restrictive cardiomyopathy. Orthologous to human MAP2K3 (mitogen-activated protein kinase kinase 3).
