Estradiol 17-beta-dehydrogenase 8 (HSD17B8) (Ohno et al. 2008) forms a heterotetramer with carbonyl reductase family member 4 (CBR4) (Chen et al. 2009, Zhang et al. 2005). The heterotetramer has NADPH-dependent 3-ketoacyl-acyl carrier protein reductase activity which is suggested to play a role in biosynthesis of fatty acids in mitochondria (Venkatesan et al. 2014).
