Application

Sphingomyelinase from Staphylococcus aureus has been used to:
  • induce neurotoxicity in rat cortical cultures to study the protective effects of minocycline
  • determine the concentration of sphingomyelin from serum samples
  • enhance sphingomyelinase activity to study PARK9-mediated exosome biogenesis

Biochem/physiol Actions

Bacterial sphingomyelinase is active at neutral pH. When used in cell culture in vitro, it hydrolyzes the sphingomyelin on the outer leaflet of the plasma membrane and produces ceramide that is lipid-soluble. Sphingomyelinase is the key enzyme in the sphingomyelinase/ceramide pathway, which is implicated in the pathogenesis of several neurodegenerative disorders.
Initiates the formation of sphingomyelin-based second messengers. Activates MAPK (mitogen-activated protein kinase) and SAPKs (stress-activated protein kinases); generates ceramide from sphingomyelin.

Unit Definition

One unit will hydrolyze 1.0 μmol of TNPAL-sphingomyelin per min at pH 7.4 at 37 °C.

Kufor-Rakeb syndrome (KRS) is caused by loss-of-function mutations in ATP13A2 (PARK9) and characterized by juvenile-onset parkinsonism, pyramidal signs, and cognitive decline. Previous studies suggested that PARK9 deficiency causes lysosomal dysfunction and α-synuclein (α-syn) accumulation, whereas PARK9 overexpression suppresses toxicity of

Proper metabolic activities facilitate T cell expansion and antitumor function; however, the mechanisms underlying disruption of the T cell metabolic program and function in the tumor microenvironment (TME) remain elusive. Here, we show a zinc finger protein 91-governed (ZFP91-governed) mechanism
