General annotation (Comments)

Function

Recognizes as substrates free retinal and cellular retinol-binding protein-bound retinal. Does metabolize octanal and decanal but does not metabolize citral, benzaldehyde, acetaldehyde and propanal efficiently.

Catalytic activity

Retinal + NAD(+) + H(2)O = retinoate + NADH.

Pathway

Cofactor metabolism; retinol metabolism.

Subunit structure

Homotetramer.

Subcellular location

Cytoplasm.

Tissue specificity

Found in testis and less abundantly in lung, brain, heart, liver and kidney.

Sequence similarities

Belongs to the aldehyde dehydrogenase family.
