Overlapping homologous superfamilies

Domain relationships


This entry corresponds to the TED domain of the complement components such as C3, C4 and C5. This domain contains a short highly conserved region of proteinase-binding alpha-macro-globulins contains the cysteine and a glutamine of a thiol-ester bond that is cleaved at the moment of proteinase binding, and mediates the covalent binding of the alpha-macro-globulin to the proteinase. The GCGEQ motif is highly conserved [PMID: 10625650, PMID: 11106161, PMID: 11387479, PMID: 10825534].
