About DAO

Cytogenetic location: 12q24.11 Genomic coordinates (GRCh38): 12:108,880,092-108,901,043 (from NCBI)

This gene has 8 transcripts (splice variants), 215 orthologues, 1 paralogue and is associated with 1 phenotype. Biased expression in kidney (RPKM 37.6) and liver (RPKM 29.1).

Summary

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]
