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. : Pssm-ID: 99848 Cd Length: 150 Bit Score: 261.27 E-value: 1.38e-82

Bruton's tyrosine kinase pleckstrin homology (PH) domain; Btk is a member of the Tec family of cytoplasmic protein tyrosine kinases that includes BMX, IL2-inducible T-cell kinase (Itk) and Tec. Btk plays a role in the maturation of B cells. Tec proteins general have an N-terminal PH domain, followed by a Tek homology (TH) domain, a SH3 domain, a SH2 domain and a kinase domain. The Btk PH domain binds phosphatidylinositol 3,4,5-trisphosphate and responds to signalling via phosphatidylinositol 3-kinase. The PH domain is also involved in membrane anchoring which is confirmed by the discovery of a mutation of a critical arginine residue in the BTK PH domain. This results in severe human immunodeficiency known as X-linked agammaglobulinemia (XLA) in humans and a related disorder is mice.PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

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.

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.

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.

an uncharacterized bacterial subgroup of the DEDDh 3'-5' exonuclease domain family with similarity to the epsilon subunit of DNA polymerase III; This subfamily is composed of uncharacterized bacterial proteins with similarity to the epsilon subunit of DNA polymerase III (Pol III), a multisubunit polymerase which is the main DNA replicating enzyme in bacteria, functioning as the chromosomal replicase. The Pol III holoenzyme is a complex of ten different subunits, three of which (alpha, epsilon, and theta) compose the catalytic core. The Pol III epsilon subunit, encoded by the dnaQ gene, is a DEDDh-type 3'-5' exonuclease which is responsible for the proofreading activity of the polymerase, increasing the fidelity of DNA synthesis. It contains 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. The epsilon subunit of Pol III also functions as a stabilizer of the holoenzyme complex. Pssm-ID: 99834 [Multi-domain] Cd Length: 156 Bit Score: 42.88 E-value: 1.80e-04
