Summary: MATH domain
Pfam includes annotations and additional family information from a range of different sources. These sources can be accessed via the tabs below.
The Pfam group coordinates the annotation of Pfam families in Wikipedia, but we have not yet assigned a Wikipedia article to this family. If you think that a particular Wikipedia article provides good annotation, please let us know.
This tab holds the annotation information that is stored in the Pfam database. As we move to using Wikipedia as our main source of annotation, the contents of this tab will be gradually replaced by the Wikipedia tab.
MATH domain Provide feedback
This motif has been called the Meprin And TRAF-Homology (MATH) domain. This domain is hugely expanded in the nematode C. elegans [3].

InterPro entry IPR002083
Although apparently functionally unrelated, intracellular TRAFs and extracellular meprins share a conserved region of about 180 residues, the meprin and TRAF homology (MATH) domain [PUBMED:12387856]. Meprins are mammalian tissue-specific metalloendopeptidases of the astacin family implicated in developmental, normal and pathological processes by hydrolysing a variety of proteins. Various growth factors, cytokines, and extracellular matrix proteins are substrates for meprins. They are composed of five structural domains: an N-terminal endopeptidase domain, a MAM domain (see PROSITEDOC), a MATH domain, an EGF-like domain (see PROSITEDOC) and a C-terminal transmembrane region. Meprin A and B form membrane bound homotetramer whereas homooligomers of meprin A are secreted. A proteolitic site adjacent to the MATH domain, only present in meprin A, allows the release of the protein from the membrane [PUBMED:7890660].
TRAF proteins were first isolated by their ability to interact with TNF receptors [PUBMED:8069916]. They promote cell survival by the activation of downstream protein kinases and, finally, transcription factors of the NF-kB and AP-1 family. The TRAF proteins are composed of 3 structural domains: a RING finger (see PROSITEDOC) in the N-terminal part of the protein, one to seven TRAF zinc fingers (see PROSITEDOC) in the middle and the MATH domain in the C-terminal part [PUBMED:12387856]. The MATH domain is necessary and sufficient for self-association and receptor interaction. From the structural analysis two consensus sequence recognised by the TRAF domain have been defined: a major one, [PSAT]x[QE]E and a minor one, PxQxxD [PUBMED:10518213].
The structure of the TRAF2 protein reveals a trimeric self-association of the MATH domain [PUBMED:10206649]. The domain forms a new, light-stranded antiparallel beta sandwich structure. A coiled-coil region adjacent to the MATH domain is also important for the trimerisation. The oligomerisation is essential for establishing appropriate connections to form signalling complexes with TNF receptor-1. The ligand binding surface of TRAF proteins is located in beta-strands 6 and 7 [PUBMED:10518213].

Pfam Clan
This family is a member of clan TRAF (CL0389), which has the following description:
Superfamily has a circularly permuted immunoglobulin-fold topology with extra an extra beta-strand. Families include the Math and the SIAH, or Seven in absentia, members.
The clan contains the following 8 members:
AvrL567-A MATH Sina Toxin_ToxA TRAF6_Z2 zf-ACC zf-TRAF zf-TRAF_2Alignments
We store a range of different sequence alignments for families. As well as the seed alignment from which the family is built, we provide the full alignment, generated by searching the sequence database (reference proteomes) using the family HMM. We also generate alignments using four representative proteomes (RP) sets, the UniProtKB sequence database, the NCBI sequence database, and our metagenomics sequence database. More...
View options
We make a range of alignments for each Pfam-A family. You can see a description of each above. You can view these alignments in various ways but please note that some types of alignment are never generated while others may not be available for all families, most commonly because the alignments are too large to handle.

HMM logo
HMM logos is one way of visualising profile HMMs. Logos provide a quick overview of the properties of an HMM in a graphical form. You can see a more detailed description of HMM logos and find out how you can interpret them here. More...
Trees
This page displays the phylogenetic tree for this family's seed alignment. We use FastTree to calculate neighbour join trees with a local bootstrap based on 100 resamples (shown next to the tree nodes). FastTree calculates approximately-maximum-likelihood phylogenetic trees from our seed alignment.
Note: You can also download the data file for the tree.

Structures
For those sequences which have a structure in the Protein DataBank, we use the mapping between UniProt, PDB and Pfam coordinate systems from the PDBe group, to allow us to map Pfam domains onto UniProt sequences and three-dimensional protein structures. The table below shows the structures on which the MATH domain has been found. There are 54 instances of this domain found in the PDB. Note that there may be multiple copies of the domain in a single PDB structure, since many structures contain multiple copies of the same protein sequence.
