NCI: Expressed in many peripheral tissues (high in placenta) by human HSD17B2 Gene (SDR Family), 387-aa 43-kDa Hydroxysteroid 17-Beta Dehydrogenase 2 is a potential type II membrane protein enzyme with an N-terminal type II signal-anchor motif and a C-terminal ER retention motif, likely associated with ER membranes, that uses NADH in the oxidative inactivation metabolism of testosterone and androstenedione, as well as estradiol and estrone. HSD17B2 also has 3-beta-HSD activity and 20-alpha-HSD activity toward 20-alpha-dihydroprogesterone. (NCI)
