This protein belongs to the [[aldehyde dehydrogenase]]s family of proteins. Aldehyde dehydrogenase is the second enzyme of the major oxidative pathway of [[alcohol metabolism]]. Two major liver isoforms of this enzyme, [[cytosol]]ic and [[mitochondria]]l, can be distinguished by their electrophoretic mobilities, kinetic properties, and subcellular localizations. Most Caucasians have two major isozymes, while approximately 50% of East Asians have only the cytosolic isozyme, missing the mitochondrial isozyme. A remarkably higher frequency of acute [[alcohol (drug)|alcohol]] intoxication among East Asians than among Caucasians could be related to the absence of the mitochondrial isozyme. This gene encodes the main cytosolic isoform, which has a lower affinity for [[aldehyde]]s than the mitochondrial enzyme.<ref name="entrez">{{cite web |title=Entrez Gene: ALDH1A1 |url=https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=216 |accessdate=}}</ref>

Aldehyde dehydrogenase 1 family, member A1, also known as ALDH1A1 or retinaldehyde dehydrogenase 1 (RALDH1), is an enzyme that in humans is encoded by the ALDH1A1 gene.[1][2]

Function

"The protein encoded by this gene belongs to the aldehyde dehydrogenase family. Aldehyde dehydrogenase is the next enzyme after alcohol dehydrogenase in the major pathway of alcohol metabolism. There are two major aldehyde dehydrogenase isozymes in the liver, cytosolic and mitochondrial, which are encoded by distinct genes, and can be distinguished by their electrophoretic mobility, kinetic properties, and subcellular localization. This gene encodes the cytosolic isozyme. Studies in mice show that through its role in retinol metabolism, this gene may also be involved in the regulation of the metabolic responses to high-fat diet."[3]

ALDH1A1 also belongs to the group of corneal crystallins that help maintain the transparency of the cornea.[4]

Transcriptions

"The promoter region of the gene contains an ATA box and a CCAAT box, which are located 32 and 74 bp upstream, respectively, from the transcription initiation site."[5]
