Abstract

TRADD is a signalling adaptor protein involved in tumour necrosis factor-receptor I (TNFR1)-associated apoptosis and cell survival. The decision between apoptosis and cell survival involves the interplay between two sequential signalling complexes. The plasma membrane-bound complex I is comprised of TNFR1, TRADD, the kinase RIP1, and TRAF2, which together mediate the activation of NF-kappaB. Subsequently, complex II is formed in the cytoplasm, where TRADD and RIP1 associate with FADD and caspase-8. If NF-kappaB is activated by complex I, then complex II will associate with the caspase-8 inhibitor FLIP(L) and the cell survives, while the failure to activate NF-kappaB leads to apoptosis [PubMed12887920].

The TRADD C-terminal death domain is responsible for its association with TNFR1, and with the death-domain proteins FADD and RIP1, which promote apoptosis. The TRADD N-terminal domain binds TRAF2 and promotes TRAF2 recruitment to TNFR1, thereby mediating the activation of NK-kappaB and JNK/AP1, which promote cell survival [PubMed10911999]. The N-terminal TRADD domain is composed of an alpha-beta sandwich, where the beta strands form an antiparallel beta-sheet.

Browse genome assignments for this superfamily. The SUPERFAMILY hidden Markov model library has been used to carry out SCOP domain assignments to all genomes at the superfamily level.


Alignments of sequences to 1 models in this superfamily are available by clicking on the 'Alignments' icon above. PDB sequences less than 40% identical are shown by default, but any other sequence(s) may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own sequences.


Browse and view proteins in genomes which have different domain combinations including a TRADD, N-terminal domain domain.


Examine the distribution of domain superfamilies, or families, across the major taxonomic kingdoms or genomes within a kingdom. This gives an immediate impression of how superfamilies, or families, are restricted to certain kingdoms of life.


Explore domain occurrence network where nodes represent genomes and edges are domain architectures (shared between genomes) containing the superfamily of interest.

There are 1 hidden Markov models representing the TRADD, N-terminal domain superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
