CC -!- FUNCTION: Lysosomal ceramidase that hydrolyzes sphingolipid ceramides
CC into sphingosine and free fatty acids at acidic pH (By similarity).
CC Ceramides, sphingosine, and its phosphorylated form sphingosine-1-
CC phosphate are bioactive lipids that mediate cellular signaling pathways
CC regulating several biological processes including cell proliferation,
CC apoptosis and differentiation (By similarity). Has a higher catalytic
CC efficiency towards C12-ceramides versus other ceramides (By
CC similarity). Also catalyzes the reverse reaction allowing the synthesis
CC of ceramides from fatty acids and sphingosine (By similarity). For the
CC reverse synthetic reaction, the natural sphingosine D-erythro isomer is
CC more efficiently utilized as a substrate compared to D-erythro-
CC dihydrosphingosine and D-erythro-phytosphingosine, while the fatty
CC acids with chain lengths of 12 or 14 carbons are the most efficiently
CC used (By similarity). Has also an N-acylethanolamine hydrolase activity
CC (By similarity). By regulating the levels of ceramides, sphingosine and
CC sphingosine-1-phosphate in the epidermis, mediates the calcium-induced
CC differentiation of epidermal keratinocytes (By similarity). Also
CC indirectly regulates tumor necrosis factor/TNF-induced apoptosis (By
CC similarity). By regulating the intracellular balance between ceramides
CC and sphingosine, in adrenocortical cells, probably also acts as a
CC regulator of steroidogenesis (By similarity).

CC {ECO:0000250|UniProtKB:Q13510}.
CC -!- SUBUNIT: Heterodimer; disulfide-linked. The heterodimer is composed of
CC the disulfide-linked alpha and beta chains produced by autocatalytic
CC cleavage of the precursor. {ECO:0000250|UniProtKB:Q13510}.
CC -!- SUBCELLULAR LOCATION: Lysosome {ECO:0000250|UniProtKB:Q13510}. Secreted
CC {ECO:0000250|UniProtKB:Q13510}. Note=Secretion is extremely low and
CC localization to lysosomes is mannose-6-phosphate receptor-dependent.
CC {ECO:0000250|UniProtKB:Q13510}.
CC -!- PTM: N-glycosylated. {ECO:0000250|UniProtKB:Q13510}.
CC -!- PTM: Proteolytically cleaved into two chains alpha and beta that remain
CC associated via a disulfide bond. Cleavage gives rise to a conformation
CC change that activates the enzyme. The same catalytic Cys residue
CC mediates the autoproteolytic cleavage and subsequent hydrolysis of
CC lipid substrates. The beta chain may undergo an additional C-terminal
CC processing. {ECO:0000250|UniProtKB:Q13510}.
CC -!- SIMILARITY: Belongs to the acid ceramidase family. {ECO:0000305}.
