PHYSICAL PROPERTIES

STRUCTURE

motifs/domains	an extracytoplasmic cysteine-rich pseudorepeats typical for the TNFR superfamily
	a preligand assembly domain (PLAD) in CRD1 mediating ligand-independent receptor assembly
	a small cytoplasmic domain with the serine/threonine kinase
	a DEATH domain, involved in the induction of A-Smase
	a N-Smase activation domain (NSD) is both necessary and sufficient for activation of N-Smase
	contains a membrane-proximal sequence that targets the receptor to caveolae/lipid rafts

CATEGORY

SUBCELLULAR LOCALIZATION	extracellular
	plasma membrane
text	release in exosome-like vesicles

basic FUNCTION	involved at least in two independent pathways
	acidic sphingomyelinase controlling expression of multiple TNF-responsive genes, including the apoptotic pathway
	neutral sphingomyelinase critical for the inflammatory and proliferative responses induced by TNF
	plays a key role in the initiation of inflammation, host defense, apoptosis, and cell survival through its ability to activate NFKB, mitogen-activated protein kinases, caspase-8, and other signaling responses
	potential role as a positive T-cell costimulatory molecule that is important for timely T-cell activation and effector cytokine production and the development of primary immune responses
	important for the development of secondary lymphoid organs during embryonic life, and is required for the formation of splenic compartments during adult, but not embryonic life

CELLULAR PROCESS	cell life, cell death/apoptosis

PHYSIOLOGICAL PROCESS

PATHWAY

metabolism

signaling

a component

with EED recruited to the TNFRSF1A•NSMAF•RACK1-complex

INTERACTION

DNA

RNA

small molecule

protein	interacted with only TRPC4AP, TRAF2, and IKBKG
	IGFBP5 interacts with TNFRSF1A through its N- and L-domains, and L-domain of IGFBP5 is a novel TNFRSF1A ligand that functions as a competitive TNF inhibitor)
