What is the normal function of the ALDH7A1 gene?
The ALDH7A1 gene is a member of the aldehyde dehydrogenase (ALDH) gene family. These genes provide instructions for producing enzymes that alter molecules called aldehydes. The ALDH7A1 gene provides instructions for making an enzyme called α-aminoadipic semialdehyde (α-AASA) dehydrogenase, also known as antiquitin. Within the cell, antiquitin is found in the internal fluid of the cell (cytosol) and in the nucleus. This enzyme is involved in the breakdown of the protein building block (amino acid) lysine in the brain. In one step in the breakdown of lysine to other molecules, antiquitin facilitates the conversion of α-aminoadipic semialdehyde to α-aminoadipate. The breakdown of lysine in the brain is necessary for energy production and to produce other needed molecules.
Does the ALDH7A1 gene share characteristics with other genes?
The ALDH7A1 gene belongs to a family of genes called ALDH (aldehyde dehydrogenases).
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.
