Proteins similar to C3, C4 and C5 of vertebrate complement. The vertebrate complement system, comprised of a large number of distinct plasma proteins, is an effector of both the acquired and innate immune systems. The point of convergence of the classical, alternative and lectin pathways of the complement system is the proteolytic activation of C3. C4 plays a key role in propagating the classical and lectin pathways. C5 participates in the classical and alternative pathways. The thioester bond located within the structure of C3 and C4 is central to the function of complement. C5 does not contain an active thioester bond.

1527-1676 4.47e-84

NTR/C345C domain, complement C5 subfamily; The NTR domain found in complement C5 is also known as C345C because it occurs at the C-terminus of complement C3, C4 and C5. Complement C5 is activated by C5 convertase, which itself is a complex between C3b and C3 convertase. The small cleavage fragment, C5a, is the most important small peptide mediator of inflammation, and the larger active fragment, C5b, initiates late events of complement activation. The NTR/C345C domain is important in the function of C5 as it interacts with enzymes that convert C5 to the active form, C5b. The domain has also been found to bind to complement components C6 and C7, and may specifically interact with their factor I modules.

467-610 1.01e-31

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 species that colonize higher eukaryotes. This domain is found in eukaryotic and bacterial proteins. In human A2Ms, this domain encompasses macroglobulin-like domain MG5 and 6 including bait region. In Salmonella enterica ser A2Ms, this domain encompasses MG7 and MG8 including the bait region. The Bait region is cleaved by proteases, followed by a large conformational change that blocks the target protease within a cage-like complex. This model of protease entrapment is recognized as the Venus flytrap mechanism.

1527-1676 4.47e-84

NTR/C345C domain, complement C5 subfamily; The NTR domain found in complement C5 is also known as C345C because it occurs at the C-terminus of complement C3, C4 and C5. Complement C5 is activated by C5 convertase, which itself is a complex between C3b and C3 convertase. The small cleavage fragment, C5a, is the most important small peptide mediator of inflammation, and the larger active fragment, C5b, initiates late events of complement activation. The NTR/C345C domain is important in the function of C5 as it interacts with enzymes that convert C5 to the active form, C5b. The domain has also been found to bind to complement components C6 and C7, and may specifically interact with their factor I modules.

467-610 1.01e-31

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 species that colonize higher eukaryotes. This domain is found in eukaryotic and bacterial proteins. In human A2Ms, this domain encompasses macroglobulin-like domain MG5 and 6 including bait region. In Salmonella enterica ser A2Ms, this domain encompasses MG7 and MG8 including the bait region. The Bait region is cleaved by proteases, followed by a large conformational change that blocks the target protease within a cage-like complex. This model of protease entrapment is recognized as the Venus flytrap mechanism.

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. Subsequently, many additional members of the family were identified on the basis of sequence similarity between the C-terminal domains of netrins, complement proteins C3, C4, C5, secreted frizzled-related proteins, and type I pro-collagen C-proteinase enhancer proteins (PCOLCEs), which are homologous with the N-terminal domains of tissue inhibitors of metalloproteinases (TIMPs). The TIMPs are classified as a separate family in Pfam (pfam00965). This expanded domain family has been named as the NTR module.

MG2 domain; This is the MG2 (macroglobulin) domain of alpha-2-macroglobulin in eukaryotes. 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 species that colonize higher eukaryotes. This domain is found in eukaryotic and bacterial proteins. In human A2Ms, this domain is termed macroglobulin-like (MG) domain 2 and in Salmonella enterica ser A2Ms, this is domain 4.

Proteins similar to C3, C4 and C5 of vertebrate complement. The vertebrate complement system, comprised of a large number of distinct plasma proteins, is an effector of both the acquired and innate immune systems. The point of convergence of the classical, alternative and lectin pathways of the complement system is the proteolytic activation of C3. C4 plays a key role in propagating the classical and lectin pathways. C5 participates in the classical and alternative pathways. The thioester bond located within the structure of C3 and C4 is central to the function of complement. C5 does not contain an active thioester bond.

1527-1676 4.47e-84

NTR/C345C domain, complement C5 subfamily; The NTR domain found in complement C5 is also known as C345C because it occurs at the C-terminus of complement C3, C4 and C5. Complement C5 is activated by C5 convertase, which itself is a complex between C3b and C3 convertase. The small cleavage fragment, C5a, is the most important small peptide mediator of inflammation, and the larger active fragment, C5b, initiates late events of complement activation. The NTR/C345C domain is important in the function of C5 as it interacts with enzymes that convert C5 to the active form, C5b. The domain has also been found to bind to complement components C6 and C7, and may specifically interact with their factor I modules.

Proteins similar to alpha2-macroglobulin (alpha (2)-M). Alpha (2)-M is a major carrier protein in serum. It is a broadly specific proteinase inhibitor. The structural thioester of alpha (2)-M, is involved in the immobilization and entrapment of proteases. This group contains another broadly specific proteinase inhibitor: pregnancy zone protein (PZP). PZP is a trace protein in the plasma of non-pregnant females and males which is elevated in pregnancy. Alpha (2)-M and PZ bind to placental protein-14 and may modulate its activity in T-cell growth and cytokine production thereby protecting the allogeneic fetus from attack by the maternal immune system. This group also contains C3, C4 and C5 of vertebrate complement. The vertebrate complement is an effector of both the acquired and innate immune systems The point of convergence of the classical, alternative and lectin pathways of the complement system is the proteolytic activation of C3. C4 plays a key role in propagating the classical and lectin pathways. C5 participates in the classical and alternative pathways. The thioester bond located within the structure of C3 and C4 is central to the function of complement. C5 does not contain an active thioester bond.

Alpha (2)-M is a major carrier protein in serum. The structural thioester of alpha (2)-M, is involved in the immobilization and entrapment of proteases. PZP is a trace protein in the plasma of non-pregnant females and males which is elevated in pregnancy. Alpha (2)-M and PZ bind to placental protein-14 and may modulate its activity in T-cell growth and cytokine production contributing to fetal survival. It has been suggested that thioester bond cleavage promotes the binding of PZ and alpha (2)-M to the CD91 receptor clearing them from circulation.

This group contains class II terpene cyclases, protein prenyltransferases beta subunit, two broadly specific proteinase inhibitors alpha2-macroglobulin (alpha (2)-M) and pregnancy zone protein (PZP) and, the C3 C4 and C5 components of vertebrate complement. Class II terpene cyclases include squalene cyclase (SQCY) and 2,3-oxidosqualene cyclase (OSQCY), these integral membrane proteins catalyze a cationic cyclization cascade converting linear triterpenes to fused ring compounds. The protein prenyltransferases include protein farnesyltransferase (FTase) and geranylgeranyltransferase types I and II (GGTase-I and GGTase-II) which catalyze the carboxyl-terminal lipidation of Ras, Rab, and several other cellular signal transduction proteins, facilitating membrane associations and specific protein-protein interactions. Alpha (2)-M is a major carrier protein in serum and involved in the immobilization and entrapment of proteases. PZP is a pregnancy associated protein. Alpha (2)-M and PZP are known to bind to and, may modulate, the activity of placental protein-14 in T-cell growth and cytokine production thereby protecting the allogeneic fetus from attack by the maternal immune system.

467-610 1.01e-31

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 species that colonize higher eukaryotes. This domain is found in eukaryotic and bacterial proteins. In human A2Ms, this domain encompasses macroglobulin-like domain MG5 and 6 including bait region. In Salmonella enterica ser A2Ms, this domain encompasses MG7 and MG8 including the bait region. The Bait region is cleaved by proteases, followed by a large conformational change that blocks the target protease within a cage-like complex. This model of protease entrapment is recognized as the Venus flytrap mechanism.

1550-1658 1.59e-28

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. Subsequently, many additional members of the family were identified on the basis of sequence similarity between the C-terminal domains of netrins, complement proteins C3, C4, C5, secreted frizzled-related proteins, and type I pro-collagen C-proteinase enhancer proteins (PCOLCEs), which are homologous with the N-terminal domains of tissue inhibitors of metalloproteinases (TIMPs). The TIMPs are classified as a separate family in Pfam (pfam00965). This expanded domain family has been named as the NTR module.

NTR_like domain; a beta barrel with an oligosaccharide/oligonucleotide-binding fold found in netrins, complement proteins, tissue inhibitors of metalloproteases (TIMP), and procollagen C-proteinase enhancers (PCOLCE), amongst others. In netrins, the domain plays a role in controlling axon branching in neural development, while the common function of these modules in TIMPs appears to be binding to metzincins. A subset of this family is also known as the C345C domain because it occurs as a C-terminal domain in complement C3, C4 and C5. In C5, the domain interacts with various partners during the formation of the membrane attack complex.

1527-1676 1.57e-22

NTR/C345C domain, complement C3 subfamily; The NTR domain found in complement C3 is also known as the C345C domain because it occurs at the C-terminus of complement C3, C4 and C5. Complement C3 plays a pivotal role in the activation of the complement systems, as all pathways (classical, alternative, and lectin) result in the processing of C3 by C3 convertase. The larger fragment, activated C3b, contains the NTR/C345C domain and binds covalently, via a reactive thioester, to cell surface carbohydrates including components of bacterial cell walls and immune aggregates. The smaller cleavage product, C3a, acts independently as a diffusible signal to mediate local inflammatory processes. The structure of C3 shows that the NTR/C345C domain is located in an exposed position relative to the rest of the molecule. The function of the domain in complement C3 is poorly understood.

NTR/C345C domain, complement C4 subfamily; The NTR domain found in complement C4 is also known as the C345C domain because it occurs at the C-terminus of complement C3, C4 and C5. Complement C4 is a key player in the activation of the component classical pathway. C4 is cleaved by activated C1 to yield C4a anaphylatoxin, and the larger fragment C4b, an essential component of the C3- and C5-convertase enzymes. C4b binds covalently to the surface of pathogens through a reactive thioester. The role of the NTR/C345C domain in C4 (C4b) is unclear.

MG2 domain; This is the MG2 (macroglobulin) domain of alpha-2-macroglobulin in eukaryotes. 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 species that colonize higher eukaryotes. This domain is found in eukaryotic and bacterial proteins. In human A2Ms, this domain is termed macroglobulin-like (MG) domain 2 and in Salmonella enterica ser A2Ms, this is domain 4.
