Summary of DAO
The Function of DAO
Regulates the level of the neuromodulator D-serine in the brain. Has high activity towards D-DOPA and contributes to dopamine synthesis. Could act as a detoxifying agent which removes D-amino acids accumulated during aging. Acts on a variety of D-amino acids with a preference for those having small hydrophobic side chains followed by those bearing polar, aromatic, and basic groups. Does not act on acidic amino acids.

Advanced Summary
DAO encodes for D-amino acid oxidase, but the enzyme's biological functions are unknown (R;).
High/excess amounts of DAO are found in schizophrenic patients, so it might play a role in schizophrenia (R;).
From NCBI Gene: Schizophrenia
From NCBI Gene: This gene encodes the peroxisomal enzyme D-amino acid oxidase. The enzyme is a flavoprotein which uses flavin adenine dinucleotide (FAD) as its prosthetic group. Its substrates include a wide variety of D-amino acids, but it is inactive on the naturally occurring L-amino acids. Its biological function is not known; it may act as a detoxifying agent which removes D-amino acids that accumulate during aging. In mice, it degrades D-serine, a co-agonist of the NMDA receptor. This gene may play a role in the pathophysiology of schizophrenia. [provided by RefSeq, Jul 2008] From UniProt: Regulates the level of the neuromodulator D-serine in the brain.
