What is the normal function of the ALDH3A2 gene?
The ALDH3A2 gene is a member of the aldehyde dehydrogenase (ALDH) gene family. Genes in this family provide instructions for producing enzymes that alter molecules called aldehydes. The ALDH3A2 gene provides instructions for making an enzyme called fatty aldehyde dehydrogenase (FALDH). This enzyme is involved in the breakdown of fats, specifically the breakdown of molecules called fatty aldehydes to fatty acids. This conversion of molecules is part of a multistep process called fatty acid oxidation in which fats are broken down and converted into energy.
The FALDH enzyme is found in most tissues, but its activity (expression) is highest in the liver. Within cells, the FALDH enzyme is located in the endoplasmic reticulum, a structure involved in protein processing and transport.
Does the ALDH3A2 gene share characteristics with other genes?
The ALDH3A2 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.
