ribonuclease III, bacterial; This family consists of bacterial examples of ribonuclease III. This enzyme cleaves double-stranded rRNA. It is involved in processing ribosomal RNA precursors. It is found even in minimal genones such as Mycoplasma genitalium and Buchnera aphidicola, and in some cases has been shown to be an essential gene. These bacterial proteins contain a double-stranded RNA binding motif (pfam00035) and a ribonuclease III domain (pfam00636). Eukaryotic homologs tend to be much longer proteins with additional domains, localized to the nucleus, and not included in this family. [Transcription, RNA processing]

RIBOc. Ribonuclease III C terminal domain. This group consists of eukaryotic, bacterial and archeal ribonuclease III (RNAse III) proteins. RNAse III is a double stranded RNA-specific endonuclease. Prokaryotic RNAse III is important in post-transcriptional control of mRNA stability and translational efficiency. It is involved in the processing of ribosomal RNA precursors. Prokaryotic RNAse III also plays a role in the maturation of tRNA precursors and in the processing of phage and plasmid transcripts. Eukaryotic RNase III's participate (through direct cleavage) in rRNA processing, in processing of small nucleolar RNAs (snoRNAs) and snRNA's (components of the spliceosome). In eukaryotes RNase III or RNaseIII like enzymes such as Dicer are involved in RNAi (RNA interference) and miRNA (micro-RNA) gene silencing.

Ribonuclease-III-like; Members of this family are involved in rDNA transcription and rRNA processing. They probably also cleave a stem-loop structure at the 3' end of U2 snRNA to ensure formation of the correct U2 3' end; they are involved in polyadenylation-independent transcription termination. Some members may be mitochondrial ribosomal protein subunit L15, others may be 60S ribosomal protein L3.

They probably also cleave a stem-loop structure at the 3' end of U2 snRNA to ensure formation of the correct U2 3' end; they are involved in polyadenylation-independent transcription termination. Some members may be mitochondrial ribosomal protein subunit L15, others may be 60S ribosomal protein L3.

 154-210 1.84e-15

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.

Double-stranded RNA binding motif; Sequences gathered for seed by HMM_iterative_training Putative motif shared by proteins that bind to dsRNA. At least some DSRM proteins seem to bind to specific RNA targets. Exemplified by Staufen, which is involved in localization of at least five different mRNAs in the early Drosophila embryo. Also by interferon-induced protein kinase in humans, which is part of the cellular response to dsRNA.

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.
