Summaries for DDAH1 Gene

Entrez Gene Summary for DDAH1 Gene

  • This gene belongs to the dimethylarginine dimethylaminohydrolase (DDAH) gene family. The encoded enzyme plays a role in nitric oxide generation by regulating cellular concentrations of methylarginines, which in turn inhibit nitric oxide synthase activity. [provided by RefSeq, Jul 2008]

GeneCards Summary for DDAH1 Gene

DDAH1 (Dimethylarginine Dimethylaminohydrolase 1) 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 DDAH2.

UniProtKB/Swiss-Prot for DDAH1 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.
