Staufen C-terminal domain; This is the C-terminal domain of Staufen proteins. It consists of an N-terminal Staufen-swapping motif (SSM) comprising two alpha helices, connected by a linker region to a dsRNA-binding-like domain ('RBD'). The 'RBD' has the fold of a functional dsRNA-binding domain, but lacks the residues required to bind RNA. This domain is responsible for dimerization, the SSM from one molecule interacts with the 'RBD' of another.

PRKRA (also known as interferon-inducible double-stranded RNA-dependent protein kinase activator A, PKR-associated protein X (RAX), PKR-associating protein X, protein kinase, interferon-inducible double-stranded RNA-dependent activator, PACT, or HSD14) is a cellular activator for double-stranded RNA-dependent protein kinase during stress signaling. TARBP2 (also called TAR RNA-binding protein 2, or trans-activation-responsive RNA-binding protein (TRBP)), participates in the formation of the RNA-induced silencing complex (RISC). It is part of the RISC-loading complex (RLC), together with dicer1 and eif2c2/ago2, and is required to process precursor miRNAs. This family also includes Drosophila melanogaster Loquacious and similar proteins. Loquacious (Loqs) is a double-stranded RNA-binding domain (dsRBD) protein, a homolog of human TAR RNA binding protein (TRBP) that is a protein first identified as binding the HIV trans-activator RNA (TAR). Loqs interacts with Dicer1 (dmDcr1) to facilitate miRNA processing. PRKRA family proteins contain three double-stranded RNA binding motifs (DSRMs). This model describes the first motif.

The DSRM domains are found in a variety of proteins including dsRNA dependent protein kinase PKR, RNA helicases, Drosophila Staufen protein, E. coli RNase III, RNase H1, and dsRNA dependent adenosine deaminases. They are involved in numerous cellular mechanisms ranging from localization and transport of messenger RNAs, through maturation and degradation of RNAs, to viral response and signal transduction. Some members harbor tandem DSRMs that act in small RNA biogenesis.

double-stranded RNA binding motif of ribonuclease III (RNase III) and similar proteins; RNase III (EC 3.1.26.3; also known as ribonuclease 3) digests double-stranded RNA formed within single-strand substrates, but not RNA-DNA hybrids. It is involved in the processing of rRNA precursors, viral transcripts, some mRNAs, and at least 1 tRNA (metY, a minor form of tRNA-init-Met). It cleaves the 30S primary rRNA transcript to yield the immediate precursors to the 16S and 23S rRNAs. The cleavage can occur in assembled 30S, 50S, and even 70S subunits and is influenced by the presence of ribosomal proteins. The RNase III family also includes the mitochondrion-specific ribosomal protein mL44 subfamily, which is composed of mitochondrial 54S ribosomal protein L3 (MRPL3) and mitochondrial 39S ribosomal protein L44 (MRPL44). Members of this family contain an RNase III domain and a C-terminal double-stranded RNA binding motif (DSRM). DSRM is not sequence specific, but highly specific for dsRNAs of various origin and structure.

ILF3 (also known as double-stranded RNA-binding protein 76 (DRBP76), M-phase phosphoprotein 4 (MPP4), nuclear factor associated with dsRNA (NFAR), nuclear factor of activated T-cells 90 kDa (NF-AT-90), or translational control protein 80 (TCP80)) is an RNA-binding protein that plays an essential role in the biogenesis of circular RNAs (circRNAs) which are produced by back-splicing circularization of pre-mRNAs. RED1 (EC 3.5.4.37; also called double-stranded RNA-specific editase 1, RNA-editing enzyme 1, dsRNA adenosine deaminase, ADARB1, ADAR2, or DRADA2) catalyzes the hydrolytic deamination of adenosine to inosine in double-stranded RNA (dsRNA), referred to as A-to-I RNA editing. RED2 (also called double-stranded RNA-specific editase B2, RNA-dependent adenosine deaminase 3, RNA-editing enzyme 2, dsRNA adenosine deaminase B2, ADAR3, or ADARB2) prevents the binding of other ADAR enzymes to targets in vitro, and decreases the efficiency of these enzymes. It is capable of binding to dsRNA but also to ssRNA. RED2 lacks editing activity for currently known substrate RNAs. Members of this group contain two double-stranded RNA binding motifs (DSRMs).

double-stranded RNA binding motif of protein SON and similar proteins; Protein SON (also known as Bax antagonist selected in saccharomyces 1 (BASS1), negative regulatory element-binding protein (NRE-binding protein), or protein DBP-5, or SON3) is an RNA-binding protein which acts as an mRNA splicing cofactor by promoting efficient splicing of transcripts that possess weak splice sites. It specifically promotes splicing of many cell-cycle and DNA-repair transcripts that possess weak splice sites, such as TUBG1, KATNB1, TUBGCP2, AURKB, PCNT, AKT1, RAD23A, and FANCG. Members of this group contain a double-stranded RNA binding motif (DSRM) at the C-terminus. DSRM is not sequence specific, but highly specific for dsRNAs of various origin and structure.

second double-stranded RNA binding motif of PRKRA, TARBP2 and similar proteins; The family includes protein activator of the interferon-induced protein kinase (PRKRA) and the RISC-loading complex subunit TARBP2. PRKRA (also known as interferon-inducible double-stranded RNA-dependent protein kinase activator A, PKR-associated protein X (RAX), PKR-associating protein X, protein kinase, interferon-inducible double-stranded RNA-dependent activator, PACT, or HSD14) is a cellular activator for double-stranded RNA-dependent protein kinase during stress signaling. TARBP2 (also called TAR RNA-binding protein 2, or trans-activation-responsive RNA-binding protein (TRBP)) participates in the formation of the RNA-induced silencing complex (RISC). It is part of the RISC-loading complex (RLC), together with dicer1 and eif2c2/ago2, and is required to process precursor miRNAs. The family also includes Drosophila melanogaster Loquacious and similar proteins. Loquacious (Loqs) is a double-stranded RNA-binding domain (dsRBD) protein, a homolog of human TAR RNA binding protein (TRBP) that is a protein first identified as binding the HIV trans-activator RNA (TAR). Loqs interacts with Dicer1 (dmDcr1) to facilitate miRNA processing. PRKRA family proteins contain three double-stranded RNA binding motifs (DSRMs). This model describes the second motif. DSRM is not sequence specific, but highly specific for dsRNAs of various origin and structure.

first double-stranded RNA binding motif of Drosophila melanogaster maternal effect protein Staufen and similar proteins; Staufen is a double-stranded RNA binding protein required both for the localization of maternal determinants to the posterior pole of the egg, oskar (osk) RNA, and for correct localization to the anterior pole, anchoring bicoid (bcd) RNA. The family also includes two Staufen homologs from vertebrates, Staufen 1 and Staufen 2. They are present in distinct ribonucleoprotein complexes and associate with different mRNAs. Staufen 1 may play a role in specific positioning of mRNAs at given sites in the cell by cross-linking cytoskeletal and RNA components, and in stimulating their translation at the site. It binds double-stranded RNA (regardless of the sequence) and tubulin. Staufen 2 is an RNA-binding protein required for the microtubule-dependent transport of neuronal RNA from the cell body to the dendrite. Staufen proteins contain five double-stranded RNA binding motifs (DSRMs). This model describes the first motif.

second double-stranded RNA binding motif of the RISC-loading complex subunit TARBP2 and similar proteins; TARBP2 (also known as TAR RNA-binding protein 2, or trans-activation-responsive RNA-binding protein (TRBP)) participates in the formation of the RNA-induced silencing complex (RISC). It is part of the RISC-loading complex (RLC), together with dicer1 and eif2c2/ago2, and is required to process precursor miRNAs. TARBP2 contains three double-stranded RNA binding motifs (DSRMs). This model describes the second motif. DSRM is not sequence specific, but highly specific for dsRNAs of various origin and structure.

second double-stranded RNA binding motif of protein activator of the interferon-induced protein kinase (PRKRA) and similar proteins; PRKRA (also known as interferon-inducible double-stranded RNA-dependent protein kinase activator A, PKR-associated protein X (RAX), PKR-associating protein X, protein kinase, interferon-inducible double-stranded RNA-dependent activator, PACT, or HSD14) is a cellular activator for double-stranded RNA-dependent protein kinase during stress signaling. PRKRA contains three double-stranded RNA binding motifs (DSRMs). This model describes the second motif. DSRM is not sequence specific, but highly specific for dsRNAs of various origin and structure.
