General annotation (Comments)

Function	Responsible for the reduction of the keto group on the C-3 of sterols.
Catalytic activity	4-alpha-methyl-5-alpha-cholest-7-en-3-beta-ol + NADP(+) = 4-alpha-methyl-5-alpha-cholest-7-en-3-one + NADPH. Estradiol-17-beta + NAD(P)(+) = estrone + NAD(P)H.
Pathway	Steroid biosynthesis; estrogen biosynthesis. Steroid biosynthesis; zymosterol biosynthesis; zymosterol from lanosterol: step 5/6.
Subunit structure	Binds to the short form of prolactin receptor.
Subcellular location	Membrane; Single-pass membrane protein.
Tissue specificity	Most abundant in ovaries of pregnant animals.
Post-translational modification	Phosphorylated.
Sequence similarities	Belongs to the short-chain dehydrogenases/reductases (SDR) family. ERG27 subfamily.
