    basic FUNCTION
  • interacting signal transduction events that induce inflammatory and proliferative responses to TNF stimulation
  • regulator of ceramide production
  • TNFRSF1A (TNF-R55)-associated protein essential
  • for the activation of neutral sphingomyelinase
  • mediates activation of SMPD2 as well as regulation of lysosome size by signaling pathways that operate independent from activation/membrane recruitment of PKC (Möhlig 2007)
  • involved in TNF-induced gene expression and leukocyte recruitment, contributing to the establishment of the specific immune response (Montfort 2009)
  • necessary intracellular intermediate for sickness behavior (Palin 2009)
  • recruits the WD repeat protein RACK1 to TNFRSF1A and in complex modulates the activity of SMPD3 (Philipp 2010)
