Summaries for ALDH1A2 Gene

Entrez Gene Summary for ALDH1A2 Gene

  • This protein belongs to the aldehyde dehydrogenase family of proteins. The product of this gene is an enzyme that catalyzes the synthesis of retinoic acid (RA) from retinaldehyde. Retinoic acid, the active derivative of vitamin A (retinol), is a hormonal signaling molecule that functions in developing and adult tissues. The studies of a similar mouse gene suggest that this enzyme and the cytochrome CYP26A1, concurrently establish local embryonic retinoic acid levels which facilitate posterior organ development and prevent spina bifida. Four transcript variants encoding distinct isoforms have been identified for this gene. [provided by RefSeq, May 2011]

GeneCards Summary for ALDH1A2 Gene

ALDH1A2 (Aldehyde Dehydrogenase 1 Family, Member A2) is a Protein Coding gene. Among its related pathways are Metabolism and retinoate biosynthesis I. GO annotations related to this gene include retinal binding and 3-chloroallyl aldehyde dehydrogenase activity. An important paralog of this gene is ALDH9A1.

UniProtKB/Swiss-Prot for ALDH1A2 Gene

  • 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 (By similarity).

Tocris Summary for ALDH1A2 Gene

  • Aldehyde dehydrogenase enzymes oxidize aldehydes to generate carboxylic acids for use in the muscle and heart. Numerous aldehyde dehydrogenase genes exist, of which ALDH2 is best known for its role in alcohol oxidation. Over 550 aldehyde genes have been identified across different species, which can be split into numerous families. There are 19 known human aldehyde dehydrogenase genes. ALDH2, a human mitochondrial enzyme belonging to family 2, is responsible for breaking down acetaldehyde produced by ethanol. Inhibition of aldehyde dehydrogenase therefore results in the build-up of acetaldehyde, a toxic metabolite which is thought to be responsible for 'hangover' symptoms.
