TNF-α-induced signaling by TNFR1 promotes the activation of sphingomyelin phosphodiesterase (sphingomyelinase or SMASE) signaling pathways. SMASE is a family of an agonist-activated effector enzymes that hydrolyze phospholipids on the membrane compartments to produce ceramide, a lipid-signaling molecule.

Factor associated with neutral sphingomyelinase activation (FAN or NSMAF) is an adaptor protein that constitutively binds to the neutral SMASE activation domain (NSD) of TNFR1 (Adam-Klages S et al. 1996). NSMAF (FAN) is thought to directly link TNFR1 to the activation of neutral sphingomyelinase (N-SMASE) such as sphingomyelin phosphodiesterase 2 or 3 (SMPD2, SMPD3).
