DEXH-box helicase domain of RIG-I; RIG-I (Retinoic acid-inducible gene I protein), also called ...
242-443 3.60e-140

DEXH-box helicase domain of RIG-I; RIG-I (Retinoic acid-inducible gene I protein), also called DEAD box protein 58 (DDX58), is a pathogen-recognition receptor that recognizes viral 5'-triphosphates carrying double-stranded RNA. Upon binding to these microbe-associated molecular patterns (MAMPs), RIG-I forms oligomers and promotes downstream processes that result in type I interferon production and induction of an antiviral state. The optimal ligand for RIG-I has been found to be base-paired or double-stranded RNA (dsRNA) molecules containing a 5' triphosphate (5'-ppp-dsRNA). RIG-I contains two N-terminal caspase activation and recruitment domains (CARDs), which are required for interaction with IPS-1, a superfamily 2 helicase/translocase/ATPase (SF2) domain and a C-terminal regulatory/repressor domain (RD). RIG-I is a member of the DEAD-like helicase superfamily, a diverse family of proteins involved in ATP-dependent RNA or DNA unwinding. This domain contains the ATP-binding region.

806-919 9.65e-51

C-terminal domain of Retinoic acid-inducible gene (RIG)-I protein, a cytoplasmic viral RNA receptor; Retinoic acid-inducible gene (RIG)-I protein, also called DEAD box protein 58 (DDX58), is one of three members of the RIG-I-like Receptor (RLR) family. RLRs are cytoplasmic RNA receptors that recognize non-self RNA and act as molecular sensors to detect viral pathogens. RIG-I is activated by blunt-ended double-stranded RNA with or without a 5'-triphosphate (ppp), by single-stranded RNA marked by a 5'-ppp and by polyuridine sequences. It has been found to confer resistance to many negative-sense RNA viruses, including orthomyxoviruses, rhabdoviruses, bunyaviruses, and paramyxoviruses, as well as the positive-strand hepatitis C virus. RLRs are characterized by a central DExD/H-box helicase domain and a C-terminal domain, both of which are responsible for binding viral RNA. The helicase domain catalyzes the unwinding of double stranded RNA in an ATP-dependent manner. RIG-I and MDA5 also contain two N-terminal caspase activation and recruitment domains (CARDs), which initiate downstream signaling upon viral RNA sensing.

2-92 5.88e-48

Caspase activation and recruitment domain found in RIG-I, first repeat; Caspase activation and recruitment domain (CARD) found in RIG-I (Retinoic acid Inducible Gene I, also known as Ddx58), first repeat. RIG-I is a cytoplasmic RNA helicase that plays an important role in host antiviral response by sensing incoming viral RNA. RIG-I contains two N-terminal CARD domains and a C-terminal RNA helicase. Upon activation, the signal is transferred to downstream pathways via the adaptor molecule IPS-1 (MAVS, VISA, CARDIF), leading to the induction of type I interferons. Although very similar in sequence, RIG-I recognizes different sets of viruses compared to MDA5, a related RNA helicase. RIG-I associates with IPS-1 through a CARD-CARD interaction. In general, CARDs are death domains (DDs) found associated with caspases. They are known to be important in the signaling pathways for apoptosis, inflammation, and host-defense mechanisms. DDs are protein-protein interaction domains found in a variety of domain architectures. Their common feature is that they form homodimers by self-association or heterodimers by associating with other members of the DD superfamily including PYRIN and DED (Death Effector Domain). They serve as adaptors in signaling pathways and can recruit other proteins into signaling complexes.

806-919 9.65e-51

C-terminal domain of Retinoic acid-inducible gene (RIG)-I protein, a cytoplasmic viral RNA receptor; Retinoic acid-inducible gene (RIG)-I protein, also called DEAD box protein 58 (DDX58), is one of three members of the RIG-I-like Receptor (RLR) family. RLRs are cytoplasmic RNA receptors that recognize non-self RNA and act as molecular sensors to detect viral pathogens. RIG-I is activated by blunt-ended double-stranded RNA with or without a 5'-triphosphate (ppp), by single-stranded RNA marked by a 5'-ppp and by polyuridine sequences. It has been found to confer resistance to many negative-sense RNA viruses, including orthomyxoviruses, rhabdoviruses, bunyaviruses, and paramyxoviruses, as well as the positive-strand hepatitis C virus. RLRs are characterized by a central DExD/H-box helicase domain and a C-terminal domain, both of which are responsible for binding viral RNA. The helicase domain catalyzes the unwinding of double stranded RNA in an ATP-dependent manner. RIG-I and MDA5 also contain two N-terminal caspase activation and recruitment domains (CARDs), which initiate downstream signaling upon viral RNA sensing.

C-terminal domain of RIG-I; This family of proteins represents the regulatory domain RD of RIG-I, a protein which initiates a signalling cascade that provides essential antiviral protection for the host. The RD domain binds viral RNA, activating the RIG-I ATPase by RNA-dependant dimerization. The structure of RD contains a zinc-binding domain and is thought to confer ligand specificity.

610-743 1.20e-48

C-terminal helicase domain of the endoribonuclease Dicer; Dicer ribonucleases cleave double-stranded RNA (dsRNA) precursors to generate microRNAs (miRNAs) and small interfering RNAs (siRNAs). In concert with Argonautes, these small RNAs bind complementary mRNAs to down-regulate their expression. miRNAs are processed by Dicer from small hairpins, while siRNAs are typically processed from longer dsRNA, from endogenous sources, or exogenous sources such as viral replication intermediates. Some organisms, such as Homo sapiens and Caenorhabditis elegans, encode one Dicer that generates miRNAs and siRNAs, but other organisms have multiple dicers with specialized functions. Dicer exists throughout eukaryotes, and a subset has an N-terminal helicase domain of the RIG-I-like receptor (RLR) subgroup. RLRs often function in innate immunity and Dicer helicase domains sometimes show differences in activity that correlate with roles in immunity. Dicer helicase domains are DEAD-like helicases belonging to superfamily (SF)2, a diverse family of proteins involved in ATP-dependent RNA or DNA unwinding. Similar to SF1 helicases, SF2 helicases do not form toroidal structures like SF3-6 helicases. Their helicase core consists of two similar protein domains that resemble the fold of the recombination protein RecA. This model describes the C-terminal domain, also called HelicC.

Caspase activation and recruitment domain found in RIG-I, first repeat; Caspase activation and recruitment domain (CARD) found in RIG-I (Retinoic acid Inducible Gene I, also known as Ddx58), first repeat. RIG-I is a cytoplasmic RNA helicase that plays an important role in host antiviral response by sensing incoming viral RNA. RIG-I contains two N-terminal CARD domains and a C-terminal RNA helicase. Upon activation, the signal is transferred to downstream pathways via the adaptor molecule IPS-1 (MAVS, VISA, CARDIF), leading to the induction of type I interferons. Although very similar in sequence, RIG-I recognizes different sets of viruses compared to MDA5, a related RNA helicase. RIG-I associates with IPS-1 through a CARD-CARD interaction. In general, CARDs are death domains (DDs) found associated with caspases. They are known to be important in the signaling pathways for apoptosis, inflammation, and host-defense mechanisms. DDs are protein-protein interaction domains found in a variety of domain architectures. Their common feature is that they form homodimers by self-association or heterodimers by associating with other members of the DD superfamily including PYRIN and DED (Death Effector Domain). They serve as adaptors in signaling pathways and can recruit other proteins into signaling complexes.

RIG-I receptor C-terminal domain; This is the C-terminal domain of Innate Immune Pattern-Recognition Receptor RIG-I present in homo sapiens. RIG-I is a key cytosolic pattern-recognition receptors of the vertebrate innate immune system that form the first line of defense against RNA viral infection. RNA binding to RIG-I is mediated both by the C-terminal domain and by the helicase domain. The C-terminal domain specifically binds the 5'triphosphate end with a 10-fold higher affinity compared to 5'OH-dsRNA.

242-443 3.60e-140

DEXH-box helicase domain of RIG-I; RIG-I (Retinoic acid-inducible gene I protein), also called DEAD box protein 58 (DDX58), is a pathogen-recognition receptor that recognizes viral 5'-triphosphates carrying double-stranded RNA. Upon binding to these microbe-associated molecular patterns (MAMPs), RIG-I forms oligomers and promotes downstream processes that result in type I interferon production and induction of an antiviral state. The optimal ligand for RIG-I has been found to be base-paired or double-stranded RNA (dsRNA) molecules containing a 5' triphosphate (5'-ppp-dsRNA). RIG-I contains two N-terminal caspase activation and recruitment domains (CARDs), which are required for interaction with IPS-1, a superfamily 2 helicase/translocase/ATPase (SF2) domain and a C-terminal regulatory/repressor domain (RD). RIG-I is a member of the DEAD-like helicase superfamily, a diverse family of proteins involved in ATP-dependent RNA or DNA unwinding. This domain contains the ATP-binding region.

242-443 2.05e-113

DEXH-box helicase domain of DEAD-like helicase RIG-I family proteins; Members of the RIG-I family include FANCM, dicer, Hef, and the RIG-I-like receptors. Fanconi anemia group M (FANCM) protein is a DNA-dependent ATPase component of the Fanconi anemia (FA) core complex required for the normal activation of the FA pathway, leading to monoubiquitination of the FANCI-FANCD2 complex in response to DNA damage, cellular resistance to DNA cross-linking drugs, and prevention of chromosomal breakage. Dicer ribonucleases cleave double-stranded RNA (dsRNA) precursors to generate microRNAs (miRNAs) and small interfering RNAs (siRNAs). Hef (helicase-associated endonuclease fork-structure) is involved in stalled replication fork repair. RIG-I-like receptors (RLRs) sense cytoplasmic viral RNA and comprises RIG-I, RLR-2/MDA5 (melanoma differentiation-associated protein 5) and RLR-3/LGP2 (laboratory of genetics and physiology 2). The RIG-I family is part of the DEAD-like helicase superfamily, a diverse family of proteins involved in ATP-dependent RNA or DNA unwinding. This domain contains the ATP-binding region.

806-919 9.65e-51

C-terminal domain of Retinoic acid-inducible gene (RIG)-I protein, a cytoplasmic viral RNA receptor; Retinoic acid-inducible gene (RIG)-I protein, also called DEAD box protein 58 (DDX58), is one of three members of the RIG-I-like Receptor (RLR) family. RLRs are cytoplasmic RNA receptors that recognize non-self RNA and act as molecular sensors to detect viral pathogens. RIG-I is activated by blunt-ended double-stranded RNA with or without a 5'-triphosphate (ppp), by single-stranded RNA marked by a 5'-ppp and by polyuridine sequences. It has been found to confer resistance to many negative-sense RNA viruses, including orthomyxoviruses, rhabdoviruses, bunyaviruses, and paramyxoviruses, as well as the positive-strand hepatitis C virus. RLRs are characterized by a central DExD/H-box helicase domain and a C-terminal domain, both of which are responsible for binding viral RNA. The helicase domain catalyzes the unwinding of double stranded RNA in an ATP-dependent manner. RIG-I and MDA5 also contain two N-terminal caspase activation and recruitment domains (CARDs), which initiate downstream signaling upon viral RNA sensing.

C-terminal domain of RIG-I; This family of proteins represents the regulatory domain RD of RIG-I, a protein which initiates a signalling cascade that provides essential antiviral protection for the host. The RD domain binds viral RNA, activating the RIG-I ATPase by RNA-dependant dimerization. The structure of RD contains a zinc-binding domain and is thought to confer ligand specificity.

245-443 2.12e-49

DEXH-box helicase domain of RLR-2; RIG-I-like receptor 2 (RLR-2, also known as melanoma differentiation-associated protein 5 or Mda5 and IFIH1) is a viral double-stranded RNA (dsRNA) receptor that shares sequence similarity and signaling pathways with RIG-I, yet plays essential functions in antiviral immunity through distinct specificity for viral RNA. RLR-2 recognizes the internal duplex structure, whereas RIG-I recognizes the terminus of dsRNA. RLR-2 uses direct protein-protein contacts to stack along dsRNA in a head-to-tail arrangement. The signaling domain (tandem CARD), which decorates the outside of the core RLR-2 filament, also has an intrinsic propensity to oligomerize into an elongated structure that activates the signaling adaptor, MAVS. RLR-2 uses long dsRNA as a signaling platform to cooperatively assemble the core filament, which in turn promotes stochastic assembly of the tandem CARD oligomers for signaling. LGP2 appears to positively and negatively regulate RLR-2 and RIG-I signaling, respectively. RLR-2 is a member of the DEAD-like helicase superfamily, a diverse family of proteins involved in ATP-dependent RNA or DNA unwinding. This domain contains the ATP-binding region.

610-743 1.20e-48

C-terminal helicase domain of the endoribonuclease Dicer; Dicer ribonucleases cleave double-stranded RNA (dsRNA) precursors to generate microRNAs (miRNAs) and small interfering RNAs (siRNAs). In concert with Argonautes, these small RNAs bind complementary mRNAs to down-regulate their expression. miRNAs are processed by Dicer from small hairpins, while siRNAs are typically processed from longer dsRNA, from endogenous sources, or exogenous sources such as viral replication intermediates. Some organisms, such as Homo sapiens and Caenorhabditis elegans, encode one Dicer that generates miRNAs and siRNAs, but other organisms have multiple dicers with specialized functions. Dicer exists throughout eukaryotes, and a subset has an N-terminal helicase domain of the RIG-I-like receptor (RLR) subgroup. RLRs often function in innate immunity and Dicer helicase domains sometimes show differences in activity that correlate with roles in immunity. Dicer helicase domains are DEAD-like helicases belonging to superfamily (SF)2, a diverse family of proteins involved in ATP-dependent RNA or DNA unwinding. Similar to SF1 helicases, SF2 helicases do not form toroidal structures like SF3-6 helicases. Their helicase core consists of two similar protein domains that resemble the fold of the recombination protein RecA. This model describes the C-terminal domain, also called HelicC.

2-92 5.88e-48

Caspase activation and recruitment domain found in RIG-I, first repeat; Caspase activation and recruitment domain (CARD) found in RIG-I (Retinoic acid Inducible Gene I, also known as Ddx58), first repeat. RIG-I is a cytoplasmic RNA helicase that plays an important role in host antiviral response by sensing incoming viral RNA. RIG-I contains two N-terminal CARD domains and a C-terminal RNA helicase. Upon activation, the signal is transferred to downstream pathways via the adaptor molecule IPS-1 (MAVS, VISA, CARDIF), leading to the induction of type I interferons. Although very similar in sequence, RIG-I recognizes different sets of viruses compared to MDA5, a related RNA helicase. RIG-I associates with IPS-1 through a CARD-CARD interaction. In general, CARDs are death domains (DDs) found associated with caspases. They are known to be important in the signaling pathways for apoptosis, inflammation, and host-defense mechanisms. DDs are protein-protein interaction domains found in a variety of domain architectures. Their common feature is that they form homodimers by self-association or heterodimers by associating with other members of the DD superfamily including PYRIN and DED (Death Effector Domain). They serve as adaptors in signaling pathways and can recruit other proteins into signaling complexes.

RLR-3 resembles a chimera combining a MDA5-like helicase domain and RIG-I like CTD supporting both stem and end binding. RNA binding is required for RLR-3-mediated enhancement of MDA5 activation. RLR-3 end-binding may promote nucleation of MDA5 oligomerization on dsRNA. RLR-3 is a member of the DEAD-like helicase superfamily, a diverse family of proteins involved in ATP-dependent RNA or DNA unwinding. This domain contains the ATP-binding region.

243-445 1.24e-44

DEXH-box helicase domain of endoribonuclease Dicer; Dicer ribonucleases cleave double-stranded RNA (dsRNA) precursors to generate microRNAs (miRNAs) and small interfering RNAs (siRNAs). In concert with Argonautes, these small RNAs bind complementary mRNAs to down-regulate their expression. miRNAs are processed by Dicer from small hairpins, while siRNAs are typically processed from longer dsRNA, from endogenous sources, or exogenous sources such as viral replication intermediates. Some organisms, such as Homo sapiens and Caenorhabditis elegans, encode one Dicer that generates miRNAs and siRNAs, but other organisms have multiple dicers with specialized functions. Dicers exist throughout eukaryotes, and a subset have an N-terminal helicase domain of the RIG-I-like receptor (RLR) subgroup. RLRs often function in innate immunity and Dicer helicase domains sometimes show differences in activity that correlate with roles in immunity. Dicer is a member of the DEAD-like helicase superfamily, a diverse family of proteins involved in ATP-dependent RNA or DNA unwinding. This domain contains the ATP-binding region.

Insert domain of MDA5; MDA5 (melanoma-differentiation-associated gene 5, also known as IFIH1), as well as RIG-I (Retinoic acid Inducible Gene I, also known as DDX58) and LPG2 (also known as DHX58), contain two N-terminal CARD domains and a C-terminal SF2 helicase domain. They are cytoplasmic DEAD box RNA helicases acting as key innate immune pattern-recognition receptor (PRRs) that play an important role in host antiviral response by sensing incoming viral RNA. Their SF2 helicase domain is comprised of 3 structural domains, the 2 generally conserved helicase domains and a helical domain inserted between the two domains. The inserted domain is involved in conformational changes upon ligand binding.

100-188 2.55e-38

Caspase activation and recruitment domain found in RIG-I, second repeat; Caspase activation and recruitment domain (CARD) found in RIG-I (Retinoic acid Inducible Gene I, also known as Ddx58), second repeat. RIG-I is a cytoplasmic RNA helicase that plays an important role in host antiviral response by sensing incoming viral RNA. RIG-I contains two N-terminal CARD domains and a C-terminal RNA helicase. Upon activation, the signal is transferred to downstream pathways via the adaptor molecule IPS-1 (MAVS, VISA, CARDIF), leading to the induction of type I interferons. Although very similar in sequence, RIG-I recognizes different sets of viruses compared to MDA5, a related RNA helicase. RIG-I associates with IPS-1 through a CARD-CARD interaction. In general, CARDs are death domains (DDs) found associated with caspases. They are known to be important in the signaling pathways for apoptosis, inflammation, and host-defense mechanisms. DDs are protein-protein interaction domains found in a variety of domain architectures. Their common feature is that they form homodimers by self-association or heterodimers by associating with other members of the DD superfamily including PYRIN and DED (Death Effector Domain). They serve as adaptors in signaling pathways and can recruit other proteins into signaling complexes.

RIG-I receptor C-terminal domain; This is the C-terminal domain of Innate Immune Pattern-Recognition Receptor RIG-I present in homo sapiens. RIG-I is a key cytosolic pattern-recognition receptors of the vertebrate innate immune system that form the first line of defense against RNA viral infection. RNA binding to RIG-I is mediated both by the C-terminal domain and by the helicase domain. The C-terminal domain specifically binds the 5'triphosphate end with a 10-fold higher affinity compared to 5'OH-dsRNA.

808-915 1.98e-36

C-terminal domain of Retinoic acid-inducible gene (RIG)-I-like Receptors; Retinoic acid-inducible gene (RIG)-I-like Receptors (RLRs) are cytoplasmic RNA receptors that recognize non-self RNA and act as molecular sensors to detect viral pathogens. They play crucial roles in innate antiviral responses, including the production of proinflammatory cytokines and type I interferon. There are three RLRs in vertebrates, RIG-I, LGP2, and MDA5. They are characterized by a central DExD/H-box helicase domain and a C-terminal domain, both of which are responsible for binding viral RNA. The helicase domain catalyzes the unwinding of double stranded RNA in an ATP-dependent manner. RIG-I and MDA5 also contain two N-terminal caspase activation and recruitment domains (CARDs), which initiate downstream signaling upon viral RNA sensing. They may detect partially overlapping viral substrates, including dengue virus, West Nile virus (WNV), reoviruses, and several paramyxoviruses (such as measles virus and Sendai virus). LGP2 lacks CARD and may play a regulatory role in RLR signaling. It may cooperate with either RIG-I or MDA5 to sense viral RNA.

242-422 3.60e-25

DEXH-box helicase domain of Hef; Hef (helicase-associated endonuclease fork-structure) belongs to the XPF/MUS81/FANCM family of endonucleases and is involved in stalled replication fork repair. All archaea encode a protein of the XPF/MUS81/FANCM family of endonucleases. It exists in two forms: a long form, referred as Hef which consists of an N-terminal helicase fused to a C-terminal nuclease and is specific to euryarchaea and a short form, referred as XPF which lacks the helicase domain and is specific to crenarchaea and thaumarchaea. Hef has the unique feature of having both active helicase and nuclease domains. This domain configuration is highly similar with the human FANCM, a possible ortholog of archaeal Hef proteins. Hef is a member of the DEAD-like helicase superfamily, a diverse family of proteins involved in ATP-dependent RNA or DNA unwinding. This domain contains the ATP-binding region.

809-893 3.54e-24

C-terminal domain of Retinoic acid-inducible gene (RIG)-I-like Receptors, Cereblon (CRBN), and similar protein domains; Retinoic acid-inducible gene (RIG)-I-like Receptors (RLRs) are cytoplasmic RNA receptors that recognize non-self RNA and act as molecular sensors to detect viral pathogens. They play crucial roles in innate antiviral responses, including the production of proinflammatory cytokines and type I interferon. There are three RLRs in vertebrates, RIG-I, LGP2, and MDA5. They are characterized by a central DExD/H-box helicase domain and a C-terminal domain, both of which are responsible for binding viral RNA. Cereblon is part of an E3 ubiquitin ligase complex, together with damaged DNA binding protein 1 (DDB1), CUL4A and ROC1. Cereblon interacts directly with DDB1, although the C-terminal domain characterized here does not contribute to that interaction. The C-terminal domain of Cereblon was shown to contain the binding site for thalidomide and its analogs, a class of teratogenic drugs that exhibit an antiproliferative effect on myelomas. Mutations in CRBN, some of which map onto the C-terminal domain, were associated with autosomal recessive mental retardation, which may have to do with interactions between CRBN and ion channels in the brain. RLRs and Cereblon contain a common conserved zinc binding site in their C-terminal domains.

2-92 1.23e-19

Caspase activation and recruitment domains (CARDs) found in IPS-1 and RIG-I-like RNA helicases; Caspase activation and recruitment domains (CARDs) found in IPS-1 (Interferon beta promoter stimulator protein 1) and Retinoic acid Inducible Gene I (RIG-I)-like DEAD box helicases. RIG-I-like helicases and IPS-1 play important roles in the induction of interferons in response to viral infection. They are crucial in triggering innate immunity and in developing adaptive immunity against viral pathogens. RIG-I-like helicases, including MDA5 and RIG-I, contain two N-terminal CARD domains and a C-terminal DEAD box RNA helicase domain. They are cytoplasmic RNA helicases that play an important role in host antiviral response by sensing incoming viral RNA. Upon activation, the signal is transferred to downstream pathways via the adaptor molecule IPS-1 (MAVS, VISA, CARDIF), leading to the induction of type I interferons. MDA5 and RIG-I associate with IPS-1 through a CARD-CARD interaction. In general, CARDs are death domains (DDs) found associated with caspases. They are known to be important in the signaling pathways for apoptosis, inflammation, and host-defense mechanisms. DDs are protein-protein interaction domains found in a variety of domain architectures. Their common feature is that they form homodimers by self-association or heterodimers by associating with other members of the DD superfamily including PYRIN and DED (Death Effector Domain). They serve as adaptors in signaling pathways and can recruit other proteins into signaling complexes.

610-742 2.42e-19

C-terminal helicase domain of Fanconi anemia group M family helicases; Fanconi anemia group M (FANCM) protein is a DNA-dependent ATPase component of the Fanconi anemia (FA) core complex. It is required for the normal activation of the FA pathway, leading to monoubiquitination of the FANCI-FANCD2 complex in response to DNA damage, cellular resistance to DNA cross-linking drugs, and prevention of chromosomal breakage. Hef (helicase-associated endonuclease fork-structure) belongs to the XPF/MUS81/FANCM family of endonucleases and is involved in stalled replication fork repair. FANCM and Hef are DEAD-like helicases belonging to superfamily (SF)2, a diverse family of proteins involved in ATP-dependent RNA or DNA unwinding. Similar to SF1 helicases, SF2 helicases do not form toroidal structures like SF3-6 helicases. Their helicase core consists of two similar protein domains that resemble the fold of the recombination protein RecA. This model describes the C-terminal domain, also called HelicC.

245-414 1.24e-15

DEAH-box helicase domain of FANCM; Fanconi anemia group M (FANCM) protein is a DNA-dependent ATPase component of the Fanconi anemia (FA) core complex. It is required for the normal activation of the FA pathway, leading to monoubiquitination of the FANCI-FANCD2 complex in response to DNA damage, cellular resistance to DNA cross-linking drugs, and prevention of chromosomal breakage. In complex with CENPS and CENPX, it binds double-stranded DNA (dsDNA), fork-structured DNA (fsDNA), and Holliday junction substrates. Its ATP-dependent DNA branch migration activity can process branched DNA structures such as a movable replication fork. This activity is strongly stimulated in the presence of CENPS and CENPX. In complex with FAAP24, it efficiently binds to single-strand DNA (ssDNA), splayed-arm DNA, and 3'-flap substrates. In vitro, on its own, it strongly binds ssDNA oligomers and weakly fsDNA, but does not bind to dsDNA. FANCM is a member of the DEAD-like helicase superfamily, a diverse family of proteins involved in ATP-dependent RNA or DNA unwinding. This domain contains the ATP-binding region.

808-920 5.34e-14

C-terminal domain of Laboratory of Genetics and Physiology 2 (LGP2), a cytoplasmic viral RNA receptor; Laboratory of Genetics and Physiology 2 (LGP2) is one of three members of the RIG-I-like Receptor (RLR) family. RLRs are cytoplasmic RNA receptors that recognize non-self RNA and act as molecular sensors to detect viral pathogens. They are characterized by a central DExD/H-box helicase domain and a C-terminal domain, both of which are responsible for binding viral RNA. LGP2 lacks the caspase activation and recruitment domains (CARDs) that are present in other RLRs, which initiate downstream signaling upon viral RNA sensing. LGP2 may play a regulatory role in RLR signaling, and may cooperate with either RIG-I or MDA5 to sense viral RNA.

809-911 1.31e-10

C-terminal domain of Melanoma differentiation-associated protein 5, a cytoplasmic viral RNA receptor; Melanoma differentiation-associated protein 5 (MDA5) is also called Interferon-induced helicase C domain-containing protein 1 (IFIH1) or RIG-I-like receptor 2 (RLR-2). It is one of three members of the RLR family. RLRs are cytoplasmic RNA receptors that recognize non-self RNA and act as molecular sensors to detect viral pathogens. It has been shown to detect viruses from the Picornaviridae and Caliciviridae families. RLRs are characterized by a central DExD/H-box helicase domain and a C-terminal domain, both of which are responsible for binding viral RNA. The helicase domain catalyzes the unwinding of double stranded RNA in an ATP-dependent manner. RIG-I and MDA5 also contain two N-terminal caspase activation and recruitment domains (CARDs), which initiate downstream signaling upon viral RNA sensing.

244-411 1.60e-08

DEXH-box helicase domain of type III restriction enzyme res subunit; Members of this model includes both type I and type III restriction enzymes. Both are hetero-oligomeric proteins. Type I REs are encoded by three closely linked genes: a specificity subunit (HsdS or S) for recognizing a DNA sequence, a methylation subunit (HsdM or M) for methylating the recognized target bases, and a restriction subunit (HsdR or R) for the translocation and random cleavage of non-methylated DNA. They show diverse catalytic activities, including methyltransferase (MTase), ATP hydrolase (ATPase), DNA translocation and restriction activities. These enzymes cut at a site that differs, and is a random distance (at least 1000 bp) away, from their recognition site. Cleavage at these random sites follows a process of DNA translocation, which shows that these enzymes are also molecular motors. The recognition site is asymmetrical and is composed of two specific portions: one containing 3-4 nucleotides, and another containing 4-5 nucleotides, separated by a non-specific spacer of about 6-8 nucleotides. Type III enzymes are composed of two subunits, Res and Mod. The Mod subunit recognizes the DNA sequence specific for the system and is a modification methyltransferase; as such, it is functionally equivalent to the M and S subunits of type I restriction endonucleases. Res is required for restriction, although it has no enzymatic activity on its own. Type III enzymes recognize short 5-6 bp-long asymmetric DNA sequences and cleave 25-27 bp downstream to leave short, single-stranded 5' protrusions. They require the presence of two inversely oriented unmethylated recognition sites for restriction to occur. These enzymes methylate only one strand of the DNA, at the N-6 position of adenosyl residues, so newly replicated DNA will have only one strand methylated, which is sufficient to protect against restriction. Both type I and type III REs are members of the DEAD-like helicase superfamily, a diverse family of proteins involved in ATP-dependent RNA or DNA unwinding. This domain contains the ATP-binding region.

9-85 1.29e-06

Caspase activation and recruitment domain found in MDA5, first repeat; Caspase activation and recruitment domain (CARD) found in MDA5 (melanoma-differentiation-associated gene 5), first repeat. MDA5, also known as IFIH1, contains two N-terminal CARD domains and a C-terminal RNA helicase domain. MDA5 is a cytoplasmic DEAD box RNA helicase that plays an important role in host antiviral response by sensing incoming viral RNA. Upon activation, the signal is transferred to downstream pathways via the adaptor molecule IPS-1 (MAVS, VISA, CARDIF), leading to the induction of type I interferons. Although very similar in sequence, MDA5 recognizes different sets of viruses compared to RIG-I, a related RNA helicase. MDA5 associates with IPS-1 through a CARD-CARD interaction. In general, CARDs are death domains (DDs) found associated with caspases. They are known to be important in the signaling pathways for apoptosis, inflammation, and host-defense mechanisms. DDs are protein-protein interaction domains found in a variety of domain architectures. Their common feature is that they form homodimers by self-association or heterodimers by associating with other members of the DD superfamily including PYRIN and DED (Death Effector Domain). They serve as adaptors in signaling pathways and can recruit other proteins into signaling complexes.

C-terminal helicase domain of XPB-like helicases; TFIIH basal transcription factor complex helicase XPB (xeroderma pigmentosum type B) subunit (also known as DNA excision repair protein ERCC-3 or TFIIH 89 kDa subunit) is the ATP-dependent 3'-5' DNA helicase component of the core-TFIIH basal transcription factor, involved in nucleotide excision repair (NER) of DNA and, when complexed to CAK, in RNA transcription by RNA polymerase II. XPB is a DEAD-like helicase belonging to superfamily (SF)2, a diverse family of proteins involved in ATP-dependent RNA or DNA unwinding. Similar to SF1 helicases, SF2 helicases do not form toroidal structures like SF3-6 helicases. Their helicase core consists of two similar protein domains that resemble the fold of the recombination protein RecA. This model describes the C-terminal domain, also called HelicC.

9-82 6.34e-04

Caspase activation and recruitment domain: a protein-protein interaction domain; Caspase activation and recruitment domains (CARDs) are death domains (DDs) found associated with caspases. Caspases are aspartate-specific cysteine proteases with functions in apoptosis, immune signaling, inflammation, and host-defense mechanisms. In addition to caspases, proteins containing CARDs include adaptor proteins such as RAIDD, CARD9, and RIG-I-like helicases, which can form multiprotein complexes and play important roles in mediating the signals to induce immune and inflammatory responses. In general, DDs are protein-protein interaction domains found in a variety of domain architectures. Their common feature is that they form homodimers by self-association or heterodimers by associating with other members of the DD superfamily including PYRIN and DED (Death Effector Domain). They serve as adaptors in signaling pathways and can recruit other proteins into signaling complexes.

Caspase activation and recruitment domain found in MDA5, second repeat; Caspase activation and recruitment domain (CARD) found in MDA5 (melanoma-differentiation-associated gene 5), second repeat. MDA5, also known as IFIH1, contains two N-terminal CARD domains and a C-terminal RNA helicase domain. MDA5 is a cytoplasmic DEAD box RNA helicase that plays an important role in host antiviral response by sensing incoming viral RNA. Upon activation, the signal is transferred to downstream pathways via the adaptor molecule IPS-1 (MAVS, VISA, CARDIF), leading to the induction of type I interferons. Although very similar in sequence, MDA5 recognizes different sets of viruses compared to RIG-I, a related RNA helicase. MDA5 associates with IPS-1 through a CARD-CARD interaction. In general, CARDs are death domains (DDs) found associated with caspases. They are known to be important in the signaling pathways for apoptosis, inflammation, and host-defense mechanisms. DDs are protein-protein interaction domains found in a variety of domain architectures. Their common feature is that they form homodimers by self-association or heterodimers by associating with other members of the DD superfamily including PYRIN and DED (Death Effector Domain). They serve as adaptors in signaling pathways and can recruit other proteins into signaling complexes.
