Function

This protein belongs to the aldehyde dehydrogenase family of enzymes. It was originally thought to play a role in a pathway of 9-cis-retinoic acid biosynthesis in vivo. However, bioinformatics and experimental work has shown that it is more likely the aldehyde dehydrogenase of the kynurenine pathway, oxidizing 2-aminomuconate semialdehyde to 2-aminomuconic acid.^[6] Two transcript variants encoding distinct isoforms have been identified for this gene.^[7]
