ALDHs play a major role in the detoxification of alcohol-derived acetaldehyde. They are involved in the metabolism of corticosteroids, biogenic amines, neurotransmitters, and lipid peroxidation. This protein preferentially oxidizes aromatic aldehyde substrates. It may play a role in the oxidation of toxic aldehydes.

An aldehyde dehydrogenase isozyme, ALDH3, which is strongly expressed in the stomach, may play a role in the oxidation of toxic aldehydes. Using reverse genetic approach, we cloned and characterized the cDNA and the gene for the ALDH3. The full length cDNA is 1624 base pairs (bp) in length and contains an open reading frame encoding 453 amino acid residues. The deduced amino acid sequence shows a high degree of resemblance to that of rat hepatocarcinoma ALDH. The human ALDH3 gene spans about 8 kb in length and consists of 10 exons. The putative TATA and CCAAT boxes are located in the consensus upstream distance from the transcription initiation site. Southern blot analysis of total genomic DNA argues against the proposed two-gene model for the ALDH3 isozymes (Yin, S.-J., Cheng, T.-C., Chang, C.-P., Chen, Y.-J., Chao, Y.-C., Tang, H.-S., Chang, T.-M., and Wu, C.-W. (1988) Biochem. Genet. 26, 343-360). Northern blot hybridization and analysis of PCR amplification products of cellular RNA demonstrated the existence of a high level of ALDH3 mRNA in human stomach and hepatoma cells, but a very low level in the normal liver. Expression of ALDH3 cDNA in Escherichia coli yielded a protein of 55 kDa, which exhibited kinetic properties similar to that found in ALDH3 isozyme purified from human stomach and liver, and was hybridizable with rabbit anti-human-hepatoma ALDH serum.

A developmental process that is a deterioration and loss of function over time. Aging includes loss of functions such as resistance to disease, homeostasis, and fertility, as well as wear and tear. Aging includes cellular senescence, but is more inclusive. May precede death (GO:0016265) and may succeed developmental maturation (GO:0021700).

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a cAMP (cyclic AMP, adenosine 3',5'-cyclophosphate) stimulus.
Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a drug stimulus. A drug is a substance used in the diagnosis, treatment or prevention of a disease.
Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a glucocorticoid stimulus. Glucocorticoids are hormonal C21 corticosteroids synthesized from cholesterol with the ability to bind with the cortisol receptor and trigger similar effects. Glucocorticoids act primarily on carbohydrate and protein metabolism, and have anti-inflammatory effects.

A reference proteome is a set of protein sequences derived from a complete proteome which constitutes a defined standard for a particular user community. Reference proteomes are manually defined according to a number of criteria. They cover the proteomes of well- studied model organisms and other proteomes of interest for biomedical and biotechnological research. Reference proteomes have been selected to provide broad coverage of the tree of life, and constitute a representative cross-section of the taxonomic diversity to be found within UniProtKB.
