All-trans-retinol 13,14-reductase (RETSAT)

Catalyzes the saturation of all-trans-retinol to all- trans-13,14-dihydroretinol. Does not exhibit any action toward all-trans-retinoic acid, nor 9-cis, 11-cis or 13-cis-retinol isomers.

May play a role in the metabolism of vitamin A. Independently of retinol conversion, may regulate liver metabolism of MLXIPL/ChREBP.
