General annotation (Comments)

Function

Hydrolyzes the sphingolipid ceramide into sphingosine and free fatty acid at an optimal pH of 8.0. Has a highly restricted substrate specificity for the natural stereoisomer of ceramide with D-erythro-sphingosine but not D-ribo-phytosphingosine or D-erythro-dihydrosphingosine as a backbone. May have a role in regulating the levels of bioactive lipids ceramide and sphingosine 1-phosphate, as well as complex sphingolipids. Ref.1

Catalytic activity

N-acylsphingosine + H2O = a carboxylate + sphingosine.

Enzyme regulation

Inhibited by sphingosine. Inhibited by Mn2+, Zn2+, and Cu2+ in a dose-dependent manner. Slightly activated by Ca2+ in a dose-dependent manner. Ref.1

Subcellular location

Endoplasmic reticulum membrane; Multi-pass membrane protein Ref.1.

Tissue specificity

Highly expressed in skin. Weakly or not expressed in other tissues. Ref.1

Sequence similarities

Belongs to the alkaline ceramidase family.

Biophysicochemical properties

pH dependence:

Optimum pH is 8.0.
