Protein attributes

Sequence length	512 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Recognizes as substrates free retinal and cellular retinol-binding protein-bound retinal. Seems to be the key enzyme in the formation of an RA gradient along the dorso-ventral axis during the early eye development and also in the development of the olfactory system By similarity.
Catalytic activity	An aldehyde + NAD(P)(+) + H(2)O = an acid + NAD(P)H.
Pathway	Cofactor metabolism; retinol metabolism.
Subcellular location	CytoplasmBy similarity.
Tissue specificity	Expressed at low levels in many tissues and at higher levels in salivary gland, stomach, and kidney.
Sequence similarities	Belongs to the aldehyde dehydrogenase family.
