MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Ceramidases (EC 3.5.1.23), such as ASAH2, catalyze hydrolysis of the N-acyl linkage of ceramide, a second messenger in a variety of cellular events, to produce sphingosine. Sphingosine exerts both mitogenic and apoptosis-inducing activities, and its phosphorylated form functions as an intra- and intercellular second messenger (see MIM 603730) (Mitsutake et al., 2001 [PubMed 11328816]).[supplied by OMIM, Mar 2008]
PHENOTYPE: Mice homozygous for a targeted null mutation are defective in the intestinal digestion of dietary ceramide but exhibit a normal life span with no obvious abnormalities or significant alterations in total ceramide levels in major organ tissues. [provided by MGI curators]
