Protein Family Annotation Pfam Database Homepage

Chains Pfam Accession Pfam Identifier Pfam Description Type Source
B PF01759 NTR UNC-6/NTR/C345C module 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. PFAM PF01821
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
B PF00207 A2M Alpha-2-macroglobulin family Family
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
A PF07703 A2M_N_2 Alpha-2-macroglobulin family N-terminal region Family
B PF07678 A2M_comp A-macroglobulin complement component Domain This family includes the complement components region of the alpha-2-macroglobulin family. PFAM PF07678
