Protein

Fatty acid amide hydrolase 1

Gene

faah-1

Organism
Caenorhabditis elegans
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at transcript leveli

Functioni

Degrades bioactive fatty acid amides like palmitoyl ethanolamide (PEA), palmitoleoyl ethanolamide (POEA), oleoyl ethanolamide (OEA), linoleoyl ethanolamide (LOEA), arachidonoyl ethanolamide (anandamide, or AEA), and eicosapentaneoyl ethanolamide (EPEA), thereby serving to terminate the signaling functions of these molecules. EPEA promotes dauer formation and may constitute a signal of high nutrient availability. Breakdown of EPEA may promote lifespan extension when nutrient availability is high.1 Publication

Catalytic activityi

Anandamide + H2O = arachidonic acid + ethanolamine.
Oleamide + H2O = oleic acid + NH3.
