Summaries for DDAH2 Gene

Entrez Gene Summary for DDAH2 Gene

  • This gene encodes a dimethylarginine dimethylaminohydrolase. The encoded enzyme functions in nitric oxide generation by regulating the cellular concentrations of methylarginines, which in turn inhibit nitric oxide synthase activity. The protein may be localized to the mitochondria. Alternative splicing resulting in multiple transcript variants. [provided by RefSeq, Dec 2014]

GeneCards Summary for DDAH2 Gene

DDAH2 (Dimethylarginine Dimethylaminohydrolase 2) is a Protein Coding gene. Among its related pathways are eNOS activation and regulation and Metabolism. GO annotations related to this gene include amino acid binding and dimethylargininase activity. An important paralog of this gene is DDAH1.

UniProtKB/Swiss-Prot for DDAH2 Gene

  • Hydrolyzes N(G),N(G)-dimethyl-L-arginine (ADMA) and N(G)-monomethyl-L-arginine (MMA) which act as inhibitors of NOS. Has therefore a role in the regulation of nitric oxide generation.
