Enriched in several structures, including Caaaaa; Caaaap; Caaapa; Caaapp; and carbon dioxide sensory neurons based on tiling array; RNA-seq; single-cell RNA-seq; and microarray studies. Is affected by several genes including daf-2; skn-1; and glp-1 based on microarray; tiling array; and RNA-seq studies. Is affected by twenty-four chemicals including Heme; Ethanol; and mianserin based on microarray and RNA-seq studies. Human ortholog(s) of this gene implicated in coronary artery disease and hypertension. Human DDAH1 enables dimethylargininase activity. Is predicted to encode a protein with the following domain: N,N dimethylarginine dimethylhydrolase, eukaryotic. Is an ortholog of human DDAH1 (dimethylarginine dimethylaminohydrolase 1).
