180-336 5.56e-112

DEDDh 3'-5' exonuclease domain of Interferon Stimulated Gene product of 20 kDa, and similar proteins; Interferon (IFN) Stimulated Gene product of 20 kDa (ISG20) is an IFN-induced antiviral exonuclease with a strong preference for single-stranded RNA and minor activity towards single-stranded DNA. It was also independently identified by its response to estrogen and was called HEM45 (human estrogen regulated transcript). ISG20 is a DEDDh-type DnaQ-like 3'-5' exonuclease containing three conserved sequence motifs termed ExoI, ExoII and ExoIII with a specific Hx(4)D conserved pattern at ExoIII. These motifs are clustered around the active site and contain four conserved acidic residues that serve as ligands for the two metal ions required for catalysis. ISG20 may be a major effector of innate immunity against pathogens including viruses, bacteria, and parasites. It is located in promyelocytic leukemia (PML) nuclear bodies, sites for oncogenic DNA viral transcription and replication. It may carry out its function by degrading viral RNAs as part of the IFN-regulated antiviral response.

180-336 6.12e-80

DEDDh 3'-5' exonuclease domain of RNA exonuclease 4, XPMC2, Interferon Stimulated Gene product of 20 kDa, and similar proteins; This subfamily is composed of RNA exonuclease 4 (REX4 or Rex4p), XPMC2, Interferon (IFN) Stimulated Gene product of 20 kDa (ISG20), and similar proteins. REX4 is involved in pre-rRNA processing. It controls the ratio between the two forms of 5.8S rRNA in yeast. XPMC2 is a Xenopus gene which was identified through its ability to correct a mitotic defect in fission yeast. The human homolog of XPMC2 (hPMC2) may be involved in angiotensin II-induced adrenal cell cycle progression and cell proliferation. ISG20 is an IFN-induced antiviral exonuclease with a strong preference for single-stranded RNA and minor activity towards single-stranded DNA. These proteins are DEDDh-type DnaQ-like 3'-5' exonucleases containing three conserved sequence motifs termed ExoI, ExoII and ExoIII, with a specific Hx(4)D conserved pattern at ExoIII. These motifs are clustered around the active site and contain four conserved acidic residues that serve as ligands for the two metal ions required for catalysis. REX proteins function in the processing and maturation of many RNA species, similar to the function of Escherchia coli RNase T.

DEDDh 3'-5' exonuclease domain of RNA exonuclease 1, -3 and similar eukaryotic proteins; This subfamily is composed of RNA exonuclease 1 (REX1 or Rex1p), REX3 (or Rex3p), and similar eukaryotic proteins. In yeast, REX1 and REX3 are required for 5S rRNA and MRP (mitochondrial RNA processing) RNA maturation, respectively. They are DEDDh-type DnaQ-like 3'-5' exonucleases containing three conserved sequence motifs termed ExoI, ExoII and ExoIII, with a specific Hx(4)D conserved pattern at ExoIII. These motifs are clustered around the active site and contain four conserved acidic residues that serve as ligands for the two metal ions required for catalysis. REX1 is the major exonuclease responsible for pre-tRNA trail trimming and may also be involved in nuclear CCA turnover. REX proteins function in the processing and maturation of many RNA species, similar to the function of Escherichia coli RNase T.

DEDDh 3'-5' exonuclease domain of the eukaryotic exoribonucleases PAN2, RNA exonuclease (REX)-1,-3, and -4, ISG20, and similar proteins; This group is composed of eukaryotic exoribonucleases that include PAN2, RNA exonuclease 1 (REX1 or Rex1p), REX3 (Rex3p), REX4 (or Rex4p), ISG20, and similar proteins. They are DEDDh-type DnaQ-like 3'-5' exonucleases containing three conserved sequence motifs termed ExoI, ExoII and ExoIII, with a specific Hx(4)D conserved pattern at ExoIII. These motifs are clustered around the active site and contain four conserved acidic residues that serve as ligands for the two metal ions required for catalysis. PAN2 is the catalytic subunit of poly(A) nuclease (PAN), a Pab1p-dependent 3'-5' exoribonuclease which plays an important role in the posttranscriptional maturation of pre-mRNAs. REX proteins are required for the processing and maturation of many RNA species, and ISG20 is an interferon-induced antiviral exonuclease with a strong preference for single-stranded RNA.

180-336 4.72e-25

DEDDh 3'-5' exonuclease domain of the eukaryotic exoribonuclease PAN2; PAN2 is the catalytic subunit of poly(A) nuclease (PAN), a Pab1p-dependent 3'-5' exoribonuclease which plays an important role in the posttranscriptional maturation of pre-mRNAs. PAN catalyzes the deadenylation of poly(A) tails, which are initially synthesized to default lengths of 70 to 90, to mRNA-specific lengths of 55 to 71. Pab1p and PAN also play a role in the export and decay of mRNA. PAN2 contains a DEDDh-type DnaQ-like 3'-5' exonuclease domain with three conserved sequence motifs termed ExoI, ExoII and ExoIII, with a specific Hx(4)D conserved pattern at ExoIII. These motifs are clustered around the active site and contain four conserved acidic residues that serve as ligands for the two metal ions required for catalysis.

180-336 1.70e-11

DEDDh 3'-5' exonuclease domain family; DEDDh exonucleases, part of the DnaQ-like (or DEDD) exonuclease superfamily, catalyze the excision of nucleoside monophosphates at the DNA or RNA termini in the 3'-5' direction. These proteins contain four invariant acidic residues in three conserved sequence motifs termed ExoI, ExoII and ExoIII. DEDDh exonucleases are classified as such because of the presence of specific Hx(4)D conserved pattern at the ExoIII motif. The four conserved acidic residues are clustered around the active site and serve as ligands for the two metal ions required for catalysis. Most DEDDh exonucleases are the proofreading subunits (epsilon) or domains of bacterial DNA polymerase III, the main replicating enzyme in bacteria, which functions as the chromosomal replicase. Other members include other DNA and RNA exonucleases such as RNase T, Oligoribonuclease, and RNA exonuclease (REX), among others.
