190-344 | 8.07e-49 | ||||||||||
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. Pssm-ID: 350790 [Multi-domain] Cd Length: 163 Bit Score: 170.05 E-value: 8.07e-49

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.

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.

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.

DEXH-box helicase domain of RLR-3; RIG-I-like receptor 3 (RLR-3, also known as laboratory of genetics and physiology 2 or LGP2 and DHX58) appears to positively and negatively regulate MDA5 and RIG-I signaling, respectively. 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.

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.
