first double-stranded RNA binding motif of interleukin enhancer-binding factor 3 (ILF3) and similar proteins; 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. ILF3 contains an N-terminal DZF domain and two double-stranded RNA binding motifs (DSRMs). This model describes the first motif.

double-stranded RNA binding motif (DSRM) superfamily; DSRM (also known as dsRBM) is a 65-70 amino acid domain that adopts an alpha-beta-beta-beta-alpha fold. It is not sequence specific, but highly specific for double-stranded RNAs (dsRNAs) of various origin and structure. 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.

first double-stranded RNA binding motif of protein activator of the interferon-induced protein kinase (PRKRA) and similar proteins; This 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. 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. DSRM is not sequence specific, but highly specific for dsRNAs of various origin and structure.

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).
