包装
25, 50 units in glass bottle
生化/生理作用
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.
