A, C [auth D] | PF17790 | Macroglobulin domain MG1 (MG1) | Macroglobulin domain MG1 | This entry represents the N-terminal macroglobulin domain found in complement proteins C3, C4 and C5. | Domain |
A, C [auth D] | PF17791 | Macroglobulin domain MG3 (MG3) | Macroglobulin domain MG3 | This entry corresponds to the MG3 domain found in complement components C3, C4 and C5. | Domain |
A, C [auth D] | PF01835 | MG2 domain (MG2) | MG2 domain | This is the MG2 (macroglobulin) domain of alpha-2-macroglobulin in eukaryotes [1]. Alpha-2-macroglobulins (A2Ms) are plasma proteins that trap and inhibit a broad range of proteases and are major components of the eukaryotic innate immune system. How ... | Domain |
A, C [auth D] | PF00207 | Alpha-2-macroglobulin family (A2M) | Alpha-2-macroglobulin family | - | Family |
A, C [auth D] | PF01759 | UNC-6/NTR/C345C module (NTR) | UNC-6/NTR/C345C module | Sequence similarity between netrin UNC-6 and C345C complement protein family members, and hence the existence of the UNC-6 module, was first reported in [1]. Subsequently, many additional members of the family were identified on the basis of sequence ... | Domain |
A, C [auth D] | PF21406 | Complement component 3, CUB domain, first segment (C3_CUB1) | Complement component 3, CUB domain, first segment | This entry represents the first segment of the CUB domain from complement component C3, which is completed but a second segment represented in Pfam:PF21308. The CUB domain is interrupted by the TE domain. The CUB domain forms a massive, tightly packe ... | Domain |
A, C [auth D] | PF07678 | A-macroglobulin TED domain (TED_complement) | A-macroglobulin TED domain | - | Repeat |
A, C [auth D] | PF07677 | A-macroglobulin receptor binding domain (A2M_recep) | A-macroglobulin receptor binding domain | This family includes the receptor binding domain region of the alpha-2-macroglobulin family. | Domain |
A, C [auth D] | PF21308 | Complement component 3, CUB domain, second segment (C3_CUB2) | Complement component 3, CUB domain, second segment | Complement C3 is major component in the both the classical and alternative complement activation pathways. C3 is cleaved into two chains (alpha and beta) by C3 convertases. This entry represents the second segment of the CUB domain, which is complete ... | Domain |
A, C [auth D] | PF07703 | Alpha-2-macroglobulin bait region domain (A2M_BRD) | Alpha-2-macroglobulin bait region domain | Alpha-2-macroglobulins (A2Ms) are plasma proteins that trap and inhibit a broad range of proteases and are major components of the eukaryotic innate immune system. However, A2M-like proteins were identified in pathogenically invasive bacteria and spe ... | Domain |
A, C [auth D] | PF17789 | Macroglobulin domain MG4 (MG4) | Macroglobulin domain MG4 | This domain is MG4 found in complement C3 and C5 proteins. | Domain |
