Chains Pfam Accession Pfam Identifier Pfam Description Type Source
B PF07678 A2M_comp A-macroglobulin complement component Domain This family includes the complement components region of the alpha-2-macroglobulin family. PFAM PF07678
B PF00207 A2M Alpha-2-macroglobulin family Family
B PF01759 NTR UNC-6/NTR/C345C module Family
A PF07703 A2M_N_2 Alpha-2-macroglobulin family N-terminal region Family
S PF07686 V-set Immunoglobulin V-set domain Domain This domain is found in antibodies as well as neural protein P0 and CTL4 amongst others. PFAM PF07686
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. PFAM PF10569
B PF07677 A2M_recep A-macroglobulin receptor Domain This family includes the receptor domain region of the alpha-2-macroglobulin family. PFAM PF07677
A PF01835 A2M_N MG2 domain Domain This is the MG2 (macroglobulin) domain of alpha-2-macroglobulin [1]. PFAM PF01835
