Enables identical protein binding activity. Predicted to be involved in several processes, including membrane raft distribution; negative regulation of angiogenesis; and regulation of cholesterol efflux. Predicted to act upstream of or within lipid transport. Located in several cellular components, including cell body; extracellular space; and mitochondrion. Is expressed in several structures, including genitourinary system; gut; nervous system; respiratory system; and skeletal muscle tissue. Orthologous to human NAXE (NAD(P)HX epimerase).
