Function
Catalyzes the hydrolysis of sphingomyelin. Sphingomyelinases D are produced by some spider in their venoms, but also by arthropods such as ticks, or pathogenic bacteria and fungi. They might play a role in pathogenicity through different mechanisms, such as membrane destabilization and host cell penetration, but also pulmonary inflammation and cutaneous lesions.
