Comments

Comment Type Description
Catalytic Activity 17-alpha,20-alpha-dihydroxypregn-4-en-3-one + NAD(P)(+) = 17-alpha-hydroxyprogesterone + NAD(P)H.
Developmental Stage Remains repressed throughout pregnancy and becomes highly and rapidly expressed before parturition.
Function Catalyzes the conversion of progesterone into 20-alpha- dihydroprogesterone (20 alpha-OHP).
Induction Repressed by prolactin.
Ptm The N-terminus is blocked.
Similarity Belongs to the aldo/keto reductase family
Subcellular Location Cytoplasm.
Subunit Monomer.
Tissue Specificity Corpus luteum (large luteal cells).
