Comment typeDescription
Alternative ProductsEvent=Alternative splicing; Named isoforms=2; Name=1; IsoId=O70503-1; Sequence=Displayed; Name=2; IsoId=O70503-2; Sequence=VSP_020255; Note=No experimental confirmation available.;
Catalytic Activity17-beta-estradiol + NAD(P)(+) = estrone + NAD(P)H.
DomainThe di-lysine motif confers endoplasmic reticulum localization for type I membrane proteins. {ECO:0000250}.
FunctionCatalyzes 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). {ECO:0000250}.
PathwayLipid metabolism; fatty acid biosynthesis.
PathwaySteroid biosynthesis; estrogen biosynthesis.
SimilarityBelongs to the short-chain dehydrogenases/reductases (SDR) family. 17-beta-HSD 3 subfamily. {ECO:0000305}.
Subcellular LocationEndoplasmic reticulum membrane {ECO:0000250}; Multi-pass membrane protein {ECO:0000250}.
Tissue SpecificityExpressed in most tissues tested. {ECO:0000269|PubMed:12482854}.
