Protein attributes

Sequence length	312 AA.
Sequence status	Complete.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	Catalyzes the transformation of estrone (E1) into estradiol (E2), suggesting a central role in estrogen formation. Its strong expression in ovary and mammary gland suggest that it may constitute the major enzyme responsible for the conversion of E1 to E2 in females. Also has 3-ketoacyl-CoA reductase activity, reducing both long chain 3-ketoacyl-CoAs and long chain fatty acyl-CoAs, suggesting a role in long fatty acid elongation By similarity.
Catalytic activity	Estradiol-17-beta + NAD(P)+ = estrone + NAD(P)H.
Pathway	Steroid biosynthesis; estrogen biosynthesis. Lipid metabolism; fatty acid biosynthesis.
Subcellular location	Endoplasmic reticulum membrane; Multi-pass membrane protein By similarity.
Tissue specificity	Expressed in most tissues tested. Ref.4
Domain	The di-lysine motif confers endoplasmic reticulum localization for type I membrane proteins By similarity.
Sequence similarities	Belongs to the short-chain dehydrogenases/reductases (SDR) family. 17-beta-HSD 3 subfamily.
