114-358 6.98e-99

Phosphodiesterase domain of human TDP2, a 5'-tyrosyl DNA phosphodiesterase, and related domains; Human TDP2, also known as TTRAP (TRAF/TNFR-associated factors, and tumor necrosis factor receptor/TNFR-associated protein), is a 5'-tyrosyl DNA phosphodiesterase. It is required for the efficient repair of topoisomerase II-induced DNA double strand breaks. The topoisomerase is covalently linked by a phosphotyrosyl bond to the 5'-terminus of the break. TDP2 cleaves the DNA 5'-phosphodiester bond and restores 5'-phosphate termini, needed for subsequent DNA ligation, and hence repair of the break. TDP2 and 3'-tyrosyl DNA phosphodiesterase (TDP1) are complementary activities; together, they allow cells to remove trapped topoisomerase from both 3'- and 5'-DNA termini. TTRAP has been reported as being involved in apoptosis, embryonic development, and transcriptional regulation, and it may inhibit the activation of nuclear factor-kB. This family belongs to the large EEP (exonuclease/endonuclease/phosphatase) superfamily that contains functionally diverse enzymes that share a common catalytic mechanism of cleaving phosphodiester bonds.

27-63 8.40e-18

UBA-like domain found in tyrosyl-DNA phosphodiesterase 2 (TDP2) and similar proteins; TDP2, also called ETS1-associated protein II (EAPII) or TRAF and TNF receptor-associated protein (Ttrap), is a 5'-Tyr-DNA phosphodiesterase, a member of the Mg(2+)/Mn(2+)-dependent family of phosphodiesterases which contains an N-terminal ubiquitin-associated (UBA)-like domain and a C-terminal phosphodiesterase domain. TDP2 is required for the efficient repair of topoisomerase II-induced DNA double strand breaks. The topoisomerase is covalently linked by a phosphotyrosyl bond to the 5'-terminus of the break. TDP2 cleaves the DNA 5'-phosphodiester bond and restores 5'-phosphate termini needed for subsequent DNA ligation and hence repair of the break. Tyrosyl-DNA phosphodiesterase 1 (TDP1), an enzyme that cleaves 3'-phosphotyrosyl bonds, and TDP2 are complementary activities; together, they allow cells to remove trapped topoisomerase from both 3'- and 5'-DNA termini. TDP2 has been reported as being involved in apoptosis, embryonic development, and transcriptional regulation. It can associate with CD40, tumor necrosis factor receptor-75 (TNF-R75) and TNF receptor-associated factors (TRAFs) and may inhibit the activation of nuclear factor-kappa B (NF-kappaB).

27-63 8.40e-18

UBA-like domain found in tyrosyl-DNA phosphodiesterase 2 (TDP2) and similar proteins; TDP2, also called ETS1-associated protein II (EAPII) or TRAF and TNF receptor-associated protein (Ttrap), is a 5'-Tyr-DNA phosphodiesterase, a member of the Mg(2+)/Mn(2+)-dependent family of phosphodiesterases which contains an N-terminal ubiquitin-associated (UBA)-like domain and a C-terminal phosphodiesterase domain. TDP2 is required for the efficient repair of topoisomerase II-induced DNA double strand breaks. The topoisomerase is covalently linked by a phosphotyrosyl bond to the 5'-terminus of the break. TDP2 cleaves the DNA 5'-phosphodiester bond and restores 5'-phosphate termini needed for subsequent DNA ligation and hence repair of the break. Tyrosyl-DNA phosphodiesterase 1 (TDP1), an enzyme that cleaves 3'-phosphotyrosyl bonds, and TDP2 are complementary activities; together, they allow cells to remove trapped topoisomerase from both 3'- and 5'-DNA termini. TDP2 has been reported as being involved in apoptosis, embryonic development, and transcriptional regulation. It can associate with CD40, tumor necrosis factor receptor-75 (TNF-R75) and TNF receptor-associated factors (TRAFs) and may inhibit the activation of nuclear factor-kappa B (NF-kappaB).

Exonuclease-Endonuclease-Phosphatase domain; uncharacterized family 1; This family of uncharacterized proteins belongs to a superfamily that includes the catalytic domain (exonuclease/endonuclease/phosphatase, EEP, domain) of a diverse set of proteins including the ExoIII family of apurinic/apyrimidinic (AP) endonucleases, inositol polyphosphate 5-phosphatases (INPP5), neutral sphingomyelinases (nSMases), deadenylases (such as the vertebrate circadian-clock regulated nocturnin), bacterial cytolethal distending toxin B (CdtB), deoxyribonuclease 1 (DNase1), the endonuclease domain of the non-LTR retrotransposon LINE-1, and related domains. These diverse enzymes share a common catalytic mechanism of cleaving phosphodiester bonds. Their substrates range from nucleic acids to phospholipids and perhaps, proteins.

31-63 1.77e-06

UBA-like domain found in NSFL1 cofactor p47 and similar proteins; p47, also called UBX domain-containing protein 2C, is a major cofactor of the cytosolic AAA ATPase p97. It is required for the p97-regulated membrane reassembly of the endoplasmic reticulum (ER), the nuclear envelope and the Golgi apparatus. p47, together with p97, forms the p97-p47 complex that plays an important role in regulation of membrane fusion events. p47 contains an N-terminal ubiquitin-associated (UBA)-like domain, a central SEP (named after shp1, eyc and p47) domain, and a ubiquitin-like (UBX) domain. UBA-like domain is responsible for forming a highly stable complex with ubiquitin. SEP domain and UBX domain may involve in p47 trimerization or forms a stable complex with the p97 N-terminal domain.

Endonuclease domain (L1-EN) of the non-LTR retrotransposon LINE-1 (L1), and related domains; This family contains the endonuclease domain (L1-EN) of the non-LTR retrotransposon LINE-1 (L1), and related domains, including the endonuclease of Xenopus laevis Tx1. These retrotranspons belong to the subtype 2, L1-clade. LINES can be classified into two subtypes. Subtype 2 has two ORFs: the second (ORF2) encodes a modular protein consisting of an N-terminal apurine/apyrimidine endonuclease domain (EN), a central reverse transcriptase, and a zinc-finger-like domain at the C-terminus. LINE-1/L1 elements (full length and truncated) comprise about 17% of the human genome. This endonuclease nicks the genomic DNA at the consensus target sequence 5'TTTT-AA3' producing a ribose 3'-hydroxyl end as a primer for reverse transcription of associated template RNA. This subgroup also includes the endonuclease of Xenopus laevis Tx1, another member of the L1-clade. This family belongs to the large EEP (exonuclease/endonuclease/phosphatase) superfamily that contains functionally diverse enzymes that share a common catalytic mechanism of cleaving phosphodiester bonds.

UBA-like domain found in the NXF family of mRNA nuclear export factors and similar proteins; This family includes nuclear RNA export factors (NXF1/NXF2), FAS-associated factors (FAF1/2), tyrosyl-DNA phosphodiesterase 2 (TDP2), OTU domain-containing proteins (OTU7A/OTU7B), NSFL1 cofactor p47, defective in cullin neddylation protein 1 (DCN1)-like protein (DCNL1/DCNL2), yeast defective in cullin neddylation protein 1 (DCN1) and similar proteins. NXF proteins can stimulate nuclear export of mRNAs and facilitate the export of unspliced viral mRNA containing the constitutive transport element. FAF1 is an apoptotic signaling molecule that acts downstream in the Fas signal transduction pathway. It interacts with the cytoplasmic domain of Fas, but not to a Fas mutant that is deficient in signal transduction. FAF2 is the translation product of a highly expressed gene in the T-cells and eosinophils of atopic dermatitis patients compared with those of normal individuals. Its biological function remains unclear. TDP2 is a 5'-Tyr-DNA phosphodiesterase required for the efficient repair of topoisomerase II-induced DNA double strand breaks. OTU7A and OTU7B are zinc finger proteins that function as deubiquitinating enzymes. p47 is a major cofactor of the cytosolic AAA ATPase p97. It is required for the p97-regulated membrane reassembly of the endoplasmic reticulum (ER), the nuclear envelope and the Golgi apparatus. DCNL1 plays an essential role in the neddylation E3 complex and participates in the release of inhibitory effects of CAND1 on cullin-RING ligase E3 complex assembly and activity. The biological function of DCNL2 remains unclear. Yeast DCN1 is a scaffold-type E3 ligase for cullin neddylation. It can bind directly to cullins and the ubiquitin-like protein Nedd8-specific E2 (Ubc12), and regulate cullin neddylation and thus display ubiquitin ligase activity.

128-358 3.89e-05

C-terminal deadenylase domain of nocturnin and related domains; This subfamily contains the C-terminal catalytic domain of the deadenylase, nocturnin, and related domains. Nocturnin is a poly(A)-specific 3' exonuclease that specifically degrades the 3' poly(A) tail of RNA in a process known as deadenylation. This nuclease activity is manganese dependent. Nocturnin is expressed in the cytoplasm of Xenopus laevis retinal photoreceptor cells in a rhythmic fashion, and it has been proposed that it participates in posttranscriptional regulation of the circadian clock or its outputs, and that the mRNA target(s) of this deadenylase are circadian clock-related. In mouse, the nocturnin gene, mNoc, is expressed in a circadian pattern in a range of tissues including retina, spleen, heart, kidney, and liver. It is highly expressed in bone-marrow stromal cells, adipocytes and hepatocytes. In mammals, nocturnin plays a role in regulating mesenchymal stem-cell lineage allocation, perhaps through regulating PPAR-gamma (peroxisome proliferator-activated receptor-gamma) nuclear translocation. This subfamily belongs to the large EEP (exonuclease/endonuclease/phosphatase) superfamily that contains functionally diverse enzymes that share a common catalytic mechanism of cleaving phosphodiester bonds.

24-65 6.52e-04

UBA-like domain found in DCN1-like protein DCNL1, DCNL2 and similar proteins; DCNL1 (defective in cullin neddylation protein 1-like protein 1), also called DCUN1 domain-containing protein 1, is encoded by squamous cell carcinoma-related oncogene SCCRO (DCUN1D1). It interacts with known cullin isoforms as well as ROC1, Ubc12 and CAND1, the components of the neddylation pathway. It plays an essential role in the neddylation E3 complex and participates in the release of inhibitory effects of CAND1 on cullin-RING ligase E3 complex assembly and activity. DCNL1 contains an N-terminal ubiquitin-associated (UBA)-like domain and a C-terminal cullin binding domain that binds to cullins and Rbx-1, components of an E3 ubiquitin ligase complex for neddylation. DCNL2 (defective in cullin neddylation protein 1-like protein 2), also called DCUN1 domain-containing protein 2, is encoded by gene DCUN1D2. Although its biological function remains unclear, DCNL2 shows high sequence similarity with DCNL1 and may also contribute to neddylation of cullin components of SCF-type E3 ubiquitin ligase complexes. Like DCNL1, DCNL2 contains an N-terminal UBA-like domain and a C-terminal cullin binding domain.

114-153 5.69e-03

Human Ape1-like subfamily of the ExoIII family apurinic/apyrimidinic (AP) endonucleases; This subfamily includes human Ape1 (also known as Apex, Hap1, or Ref-1) and related proteins. These are Escherichia coli exonuclease III (ExoIII)-like AP endonucleases and they belong to the large EEP (exonuclease/endonuclease/phosphatase) superfamily that contains functionally diverse enzymes that share a common catalytic mechanism of cleaving phosphodiester bonds. AP endonucleases participate in the DNA base excision repair (BER) pathway. AP sites are one of the most common lesions in cellular DNA. During BER, the damaged DNA is first recognized by DNA glycosylase. AP endonucleases then catalyze the hydrolytic cleavage of the phosphodiester bond 5' to the AP site, and this is followed by the coordinated actions of DNA polymerase, deoxyribose phosphatase, and DNA ligase. If left unrepaired, AP sites block DNA replication, and have both mutagenic and cytotoxic effects. AP endonucleases can carry out a variety of excision and incision reactions on DNA, including 3'-5' exonuclease, 3'-deoxyribose phosphodiesterase, 3'-phosphatase, and occasionally, nonspecific DNase activities. Different AP endonuclease enzymes catalyze the different reactions with different efficiences. Many organisms have two AP endonucleases, usually one is the dominant AP endonuclease, the other has weak AP endonuclease activity; for example, Ape1 and Ape2 in humans. Ape1 is found in this subfamily, it exhibits strong AP-endonuclease activity but shows weak 3'-5' exonuclease and 3'-phosphodiesterase activities. Class II AP endonucleases have been classified into two families, designated ExoIII and EndoIV, based on their homology to the Escherichia coli enzymes exonuclease III (ExoIII) and endonuclease IV (EndoIV). This subfamily belongs to the ExoIII family; the EndoIV family belongs to a different superfamily.
