Summary

ALDH7A1 (aldehyde dehydrogenase 7 family member A1, HGNC:877) is a protein-coding gene on chromosome 5q23.2, encoding Alpha-aminoadipic semialdehyde dehydrogenase (P49419). Aldehyde dehydrogenase enzyme that mediates important protective effects.

The protein encoded by this gene is a member of subfamily 7 in the aldehyde dehydrogenase gene family. These enzymes are thought to play a major role in the detoxification of aldehydes generated by alcohol metabolism and lipid peroxidation. This particular member has homology to a previously described protein from the green garden pea, the 26g pea turgor protein. It is also involved in lysine catabolism that is known to occur in the mitochondrial matrix. Recent reports show that this protein is found both in the cytosol and the mitochondria, and the two forms likely arise from the use of alternative translation initiation sites. An additional variant encoding a different isoform has also been found for this gene. Mutations in this gene are associated with pyridoxine-dependent epilepsy. Several related pseudogenes have also been identified.

Function. Aldehyde dehydrogenase enzyme that mediates important protective effects. Protects cells from oxidative stress by metabolizing a number of lipid peroxidation-derived aldehydes. Involved in cellular defense against hyperosmotic stress by metabolizing betaine aldehyde to betaine, an important cellular osmolyte and methyl donor. Involved in lysine catabolism in the brain by mediating the conversion of L-aminoadipate-semialdehyde ((S)-2-amino-6-oxohexanoate) to L-2-aminoadipate. Acts as a key inhibitor of ferroptosis both by generating membrane NADH and decreasing the level of reactive aldehydes. Recruited to plasma membrane in response to ferroptotic stress and phosphorylation by AMPK, generating membrane NADH to support AIFM2/FSP1 activity, an essential ferroptosis suppressor protein. Also directly inhibits ferroptosis by decreasing lipid peroxidation via consumption of reactive aldehydes, such as 4-hydroxynonenal (4-HNE) and malonaldehyde. Also acts as a regulator of cellular energy homeostasis in response to cellular energy stress, such as starvation and hypoxia, by inhibiting COPI-mediated intracellular transport, thereby reducing cellular energy consumption.

Subunit / interactions. Homotetramer.

Subcellular location. Mitochondrion Cytoplasm. Cytosol. Cell membrane. Golgi apparatus membrane. Nucleus.

Tissue specificity. Abundant in hepatoma cells and fetal cochlea, ovary, eye, heart, adrenal gland, liver and kidney. Low levels present in adult peripheral blood leukocytes and fetal brain, thymus, spleen, skeletal muscle, lung and tongue.

Post-translational modifications. Phosphorylation at Ser-102 by AMPK in response to cellular stress, such as hypoxia or ferroptotic stress, promotes membrane localization and generation of membrane NADH.

Disease relevance. Epilepsy, early-onset, 4, vitamin B6-dependent (EPEO4) [MIM:266100] An autosomal recessive neurologic disorder ocharacterized by a combination of various seizure types. It usually occurs in the first hours of life and is unresponsive to standard anticonvulsants, responding only to immediate administration of pyridoxine hydrochloride. The disease is caused by variants affecting the gene represented in this entry.

Activity regulation. Inhibited by 4-diethylaminobenzaldehyde (DEAB); inhibition is irreversible via formation of a stable covalent acyl-enzyme stalled intermediate.

Pathway. Amine and polyamine biosynthesis; betaine biosynthesis via choline pathway; betaine from betaine aldehyde: step 1/1.

Similarity. Belongs to the aldehyde dehydrogenase family.
