Homomeric and heteromeric interactions of the extracellular domains of death receptors and death decoy receptors

Biochemical and Biophysical Research Communications, 2005
Death receptors (DRs) can induce apoptosis by oligomerization with TRAIL, whereas death decoy receptors (DcRs) cannot, due to their lack of functional intracellular death domains. However, it is not known whether DRs and DcRs can interact with one another to form oligomeric complexes prior to TRAIL binding.

Apoptotic and necrotic cell death induced by death domain receptors

Cellular and Molecular Life Sciences, 2001
Apoptosis and necrosis are two distinct forms of cell death. Caspases are indispensable as initiators and effectors of apoptotic cell death and are involved in many of the morphological and biochemical features of apoptosis. Major changes in mitochondrial membrane integrity and release of proapoptotic factors, such as cytochrome c from the ...

A death-domain-containing receptor that mediates apoptosis

Nature, 1996
The cell-killing effects of the cytokines TNF-alpha and FasL are mediated by the distinct cell-surface receptors TNFR1, TNFR2 and Fas (also known as CD95/APO-1), which are all members of a receptor superfamily that is important for regulating cell survival.

An Antagonist Decoy Receptor and a Death Domain-Containing Receptor for TRAIL

Science, 1997
TRAIL, also called Apo2L, is a cytotoxic protein that induces apoptosis of many transformed cell lines but not of normal tissues, even though its death domain–containing receptor, DR4, is expressed on both cell types. An antagonist decoy receptor (designated as TRID for TRAIL receptor without an intracellular domain) that may explain the resistant ...

Pathogen blocks host death receptor signalling by arginine GlcNAcylation of death domains

Nature, 2013
The tumour necrosis factor (TNF) family is crucial for immune homeostasis, cell death and inflammation. These cytokines are recognized by members of the TNF receptor (TNFR) family of death receptors, including TNFR1 and TNFR2, and FAS and TNF-related apoptosis-inducing ligand (TRAIL) receptors.

Role of NMDA receptor functional domains in excitatory cell death

Neuropharmacology, 2000
The mechanisms by which the NMDA receptor (NMDAR) induces excitotoxicity were investigated using a novel assay. We quantitated the capacity of wild type and mutant receptors for cell killing in CHO cells and cultured cortical neurons by measuring the activity of a co-transfected firefly luciferase expression plasmid.

Solution structure of the tumor necrosis factor receptor-1 death domain

Journal of Molecular Biology, 2001
Tumor necrosis factor receptor-1 death domain (TNFR-1 DD) is the intracellular functional domain responsible for the receptor signaling activities. The solution structure of the R347K mutant of TNFR-1 DD was solved by NMR spectroscopy. A total of 20 structures were calculated by means of hybrid distance geometry-simulated annealing using a total of ...

Prevention of Constitutive TNF Receptor 1 Signaling by Silencer of Death Domains

Science, 1999
Tumor necrosis factor receptor type 1 (TNF-R1) contains a cytoplasmic death domain that is required for the signaling of TNF activities such as apoptosis and nuclear factor kappa B (NF-κB) activation. Normally, these signals are generated only after TNF-induced receptor aggregation.

Death Effector Domain-Only Polypeptides of Caspase-8 and -10 Specifically Inhibit Death Receptor-Induced Cell Death

Biochemical and Biophysical Research Communications, 2002
Caspase-8 and -10 are thought to be involved in a signaling pathway leading to death receptor-mediated apoptosis. The prodomains of these caspases are known to form fibrous structures in the perinuclear region when overexpressed, though the meaning of the structures remains unclear.

Death domain receptors and their role in cell demise.

Journal of interferon & cytokine research : the official journal of the International Society for Interferon and Cytokine Research, 1998
Apoptotic signals are transduced by five death domain-containing receptors--TNFR1, Fas, DR3, DR4, and DR5--by binding to their ligands. The intracellular portion of all these receptors contains a region, approximately 80 amino acids long, referred to as the "death domain" (DD).
