    Chain Pfam Accession Pfam Family Identifier Pfam Description Type Comment
    A PF01835   A2M_N MG2 domain Domain This is the MG2 (macroglobulin) domain of alpha-2-macroglobulin [1]. 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

    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 PF07677   A2M_recep A-macroglobulin receptor Domain This family includes the receptor domain region of the alpha-2-macroglobulin family. Source: Pfam
