Abstract

The tumour necrosis factor receptor (TNFR) associated factors (TRAFs) act as signal transducers for both TNFRs and interleukin-1/Toll-like receptors. TRAFs function in immunity, embryonic development, stress response and bone metabolism through their induction of cell proliferation, differentiation, and apoptosis [PubMed11865024]. TRAFs are characterised by two domains: an N-terminal domain containing RING and zinc finger motifs that is essential for the activation of downstream effectors, and a C-terminal TRAF domain that is essential for self-association and receptor interaction [PubMed10518213]. The TRAF-domain like fold is a beta-sandwich consisting of 8 strands in 2 beta sheets and has a circularly permuted greek-key immunoglobulin-fold topology that contains an extra strand.

The substrate-binding domain (SBD) of the SIAH (seven in absentia homolog) family of proteins is structurally highly similar to the TRAF domain. The SIAH SBD interacts with a number of proteins, and is involved in TNF-alpha-mediated NFkappaB activation [PubMed11742346].

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 5 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 TRAF domain-like 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 5 hidden Markov models representing the TRAF domain-like superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
