General annotation (Comments)

Function

Converts sphingomyelin to ceramide. Also has phospholipase C activities toward 1,2-diacylglycerolphosphocholine and 1,2-diacylglycerolphosphoglycerol By similarity.

Catalytic activity

Sphingomyelin + H2O = N-acylsphingosine + phosphocholine.

Subunit structure

Monomer By similarity.

Subcellular location

Lysosome By similarity.

Miscellaneous

There are two types of sphingomyelinases: ASM (acid), and NSM (neutral).

Sequence similarities

Belongs to the acid sphingomyelinase family.

Contains 1 saposin B-type domain.
