Protein attributes

Sequence length	501 AA.
Sequence status	Complete.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	Major component of the eye of elephant shrews, which in contrast to other mammals, possesses both a lens- and a non-lens class-1 aldehyde dehydrogenase 1. This eye-specific form is a structural protein of the lens and, in other part of the eye, serves as the major form of ALDH1. Can convert/oxidize retinaldehyde to retinoic acid.
Catalytic activity	An aldehyde + NAD+ + H2O = a carboxylate + NADH.
Pathway	Alcohol metabolism; ethanol degradation; acetate from ethanol: step 2/2.
Subunit structure	Homotetramer By similarity.
Subcellular location	Cytoplasm By similarity.
Tissue specificity	Eye specific, with very high expression in the lens.
Sequence similarities	Belongs to the aldehyde dehydrogenase family.
