Intracellular TRAFs and extracellular meprins share a conserved region of about 180 residues, the the meprin and TRAF homology (MATH) domain which adopts a beta-sandwich structure. This is the MATH domain of TNF receptor-associated factors (TRAFs) and meprins. In TRAFS, it is essential for self-association and receptor interaction [1-3]. Meprins are mammalian tissue-specific metalloendopeptidases involved developmental, normal and pathological processes.	Domain
