    B PF07677   A2M_recep A-macroglobulin receptor Domain This family includes the receptor domain region of the alpha-2-macroglobulin family. Source: Pfam  
    B PF01759   NTR UNC-6/NTR/C345C module Family
    B PF07678   A2M_comp A-macroglobulin complement component Domain This family includes the complement components region of the alpha-2-macroglobulin family. Source: Pfam  
    B PF00207   A2M Alpha-2-macroglobulin family Family
    B PF01821   ANATO Anaphylotoxin-like domain Domain C3a, C4a and C5a anaphylatoxins are protein fragments generated enzymatically in serum during activation of complement molecules C3, C4, and C5. They induce smooth muscle contraction. These fragments are homologous to a three-fold repeat in fibulins. Source: Pfam  
    B PF10569   Thiol-ester_cl Alpha-macro-globulin thiol-ester bond-forming region Domain This 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. Source: Pfam
