**Background of DAOA Recombinant Protein**
The DAOA (D-amino acid oxidase activator) gene, also known as G72. is located on chromosome 13q33 and encodes a protein implicated in modulating the activity of D-amino acid oxidase (DAO), an enzyme responsible for oxidizing D-serine—a co-agonist of the NMDA receptor critical for glutamatergic neurotransmission. Dysregulation of the DAOA-DAO pathway has been linked to neuropsychiatric disorders, particularly schizophrenia, with genetic studies identifying DAOA as a susceptibility locus.
Recombinant DAOA protein is engineered through molecular cloning and expression systems (e.g., *E. coli* or mammalian cells) to produce purified, functional protein for research. Its production enables the study of DAOA’s molecular interactions, particularly its role in DAO activation and subsequent effects on D-serine levels, which influence NMDA receptor function. Altered NMDA signaling is associated with cognitive deficits and psychosis, making DAOA a target for elucidating disease mechanisms.
Research on DAOA recombinant protein also explores its potential therapeutic applications. For instance, modulating DAOA activity could restore D-serine homeostasis, offering a strategy for treating schizophrenia or other disorders linked to glutamatergic dysfunction. Additionally, structural studies using recombinant DAOA help map functional domains and identify binding sites for drug development.
Despite progress, the exact physiological role of DAOA remains partially unclear, with conflicting data on its interaction with DAO across studies. Recombinant DAOA tools continue to be vital for resolving these ambiguities and advancing translational research in neuropsychiatry.
