Aldehyde dehydrogenase 3 family member B2 (ALDH3B2) is a member of the aldehyde dehydrogenase (ALDH) superfamily, enzymes critical for detoxifying endogenous and exogenous aldehydes through their oxidation to carboxylic acids. Encoded by the *ALDH3B2* gene located on human chromosome 11. this cytoplasmic protein shares structural homology with other ALDH family members, including a conserved NAD(P)+-binding domain and catalytic residues. ALDH3B2 is expressed in various tissues, such as the liver, lungs, and skin, though its expression levels are generally lower compared to isoforms like ALDH3A1.
Functionally, ALDH3B2 participates in metabolizing reactive aldehydes generated by lipid peroxidation, environmental toxins, or alcohol metabolism, thereby mitigating oxidative stress and cellular damage. However, its substrate specificity and catalytic efficiency remain less characterized than those of other ALDH isoforms. Emerging studies suggest potential roles in cancer progression, as altered ALDH3B2 expression has been observed in certain malignancies, possibly influencing drug resistance or tumor survival. Additionally, polymorphisms in *ALDH3B2* have been investigated for associations with diseases like asthma and neurodegenerative disorders, though evidence remains preliminary.
Despite its classification, ALDH3B2's physiological significance is still under exploration, with ongoing research aiming to clarify its distinct biochemical properties and therapeutic relevance in detoxification pathways and disease mechanisms.
