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.

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.

STRBP is a double-stranded DNA and RNA binding protein that is involved in spermatogenesis and sperm function. It plays a role in regulation of cell growth. 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). 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 metazoan ribonuclease III (RNase III) and similar proteins; RNase III (EC 3.1.26.3; also known as Drosha, or ribonuclease 3) is a double-stranded RNA (dsRNA)-specific endoribonuclease that is involved in the initial step of microRNA (miRNA) biogenesis. It is a component of the microprocessor complex that is required to process primary miRNA transcripts (pri-miRNAs) to release precursor miRNA (pre-miRNA) in the nucleus. Within the microprocessor complex, RNase III cleaves the 3' and 5' strands of a stem-loop in pri-miRNAs (processing center 11 bp from the dsRNA-ssRNA junction) to release hairpin-shaped pre-miRNAs that are subsequently cut by the cytoplasmic DICER to generate mature miRNAs. It is also involved in pre-rRNA processing. Metazoan RNase III is a larger protein than bacterial RNase III. It contains two RNase III domains in the C-terminal half of the protein followed by a double-stranded RNA binding motif (DSRM). DSRM is not sequence specific, but highly specific for dsRNAs of various origin and structure.

second double-stranded RNA binding motif of spermatid perinuclear RNA-binding protein (STRBP) and similar proteins; STRBP is a double-stranded DNA and RNA binding protein that is involved in spermatogenesis and sperm function. It plays a role in regulation of cell growth. STRBP contains an N-terminal DZF domain and two 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.
