VapC-like PIN domain of human telomerase-binding protein EST1, Smg6, and other similar ...
1210-1385 1.32e-95

VapC-like PIN domain of human telomerase-binding protein EST1, Smg6, and other similar eukaryotic homologs; Nonsense-mediated decay (NMD) factors, Smg5 and Smg6 are essential to the post-transcriptional regulatory pathway, NMD, which recognizes and rapidly degrades mRNAs containing premature translation termination codons. In vivo, the Smg6 PIN (PilT N terminus) domain elicits degradation of bound mRNAs, as well as, metal ion dependent, degradation of single-stranded RNA, in vitro. The PIN domain belongs to a large nuclease superfamily. The structural properties of the PIN domain indicate its putative active center, consisting of invariant acidic amino acid residues (putative metal-binding residues), is geometrically similar in the active center of structure-specific 5' nucleases (also known as Flap endonuclease-1-like), PIN-domain ribonucleases of eukaryotic rRNA editing proteins, and bacterial toxins of toxin-antitoxin (TA) operons. PIN domains within this subgroup contain four highly conserved acidic residues (putative metal-binding, active site residues) which cluster at the C-terminal end of the beta-sheet and form a negatively charged pocket near the center of the molecule. Point mutation studies of the conserved aspartate residues in the catalytic center of the Smg6 PIN domain revealed that Smg6 is the endonuclease involved in human NMD. However, Smg5 lacks several of these key catalytic residues and does not degrade single-stranded RNA, in vivo. Eukaryotic Smg6 PIN domains are present at the C-terminal end of the telomerase activating proteins, EST1.

VapC-like PIN domain of human telomerase-binding protein EST1, Smg6, and other similar ...
1210-1385 1.32e-95

VapC-like PIN domain of human telomerase-binding protein EST1, Smg6, and other similar eukaryotic homologs; Nonsense-mediated decay (NMD) factors, Smg5 and Smg6 are essential to the post-transcriptional regulatory pathway, NMD, which recognizes and rapidly degrades mRNAs containing premature translation termination codons. In vivo, the Smg6 PIN (PilT N terminus) domain elicits degradation of bound mRNAs, as well as, metal ion dependent, degradation of single-stranded RNA, in vitro. The PIN domain belongs to a large nuclease superfamily. The structural properties of the PIN domain indicate its putative active center, consisting of invariant acidic amino acid residues (putative metal-binding residues), is geometrically similar in the active center of structure-specific 5' nucleases (also known as Flap endonuclease-1-like), PIN-domain ribonucleases of eukaryotic rRNA editing proteins, and bacterial toxins of toxin-antitoxin (TA) operons. PIN domains within this subgroup contain four highly conserved acidic residues (putative metal-binding, active site residues) which cluster at the C-terminal end of the beta-sheet and form a negatively charged pocket near the center of the molecule. Point mutation studies of the conserved aspartate residues in the catalytic center of the Smg6 PIN domain revealed that Smg6 is the endonuclease involved in human NMD. However, Smg5 lacks several of these key catalytic residues and does not degrade single-stranded RNA, in vivo. Eukaryotic Smg6 PIN domains are present at the C-terminal end of the telomerase activating proteins, EST1.

VapC-like PIN domain of Saccharomyces cerevisiae Swt1p, human SWT1 and related proteins; Saccharomyces cerevisiae mRNA-processing endoribonuclease Swt1p plays an important role in quality control of nuclear mRNPs in eukaryotes. Human transcriptional protein SWT1 (RNA endoribonuclease homolog, also known as HsSwt1, C1orf26, and chromosome 1 open reading frame 26) is an RNA endonuclease that participates in quality control of nuclear mRNPs and can associate with the nuclear pore complex (NPC). This subfamily belongs to the Smg5 and Smg6-like PIN domain family. Smg5 and Smg6 are essential factors in NMD, a post-transcriptional regulatory pathway that recognizes and rapidly degrades mRNAs containing premature translation termination codons. In vivo, the Smg6 PIN domain elicits degradation of bound mRNAs, as well as, metal-ion dependent, degradation of single-stranded RNA, in vitro.

1216-1303 1.26e-10

VapC-like PIN domain of human nonsense-mediated decay factor Smg5, and other similar eukaryotic homologs; Nonsense-mediated decay (NMD) factors, Smg5 and Smg6 are essential to the post-transcriptional regulatory pathway, NMD, which recognizes and rapidly degrades mRNAs containing premature translation termination codons. The PIN (PilT N terminus) domain belongs to a large nuclease superfamily. The structural properties of the PIN domain indicate its putative active center, consisting of invariant acidic amino acid residues (putative metal-binding residues), is geometrically similar in the active center of structure-specific 5' nucleases (also known as Flap endonuclease-1-like), PIN-domain ribonucleases of eukaryotic rRNA editing proteins, and bacterial toxins of toxin-antitoxin (TA) operons. Point mutation studies of the conserved aspartate residues in the catalytic center of the Smg6 PIN domain revealed that Smg6 is the endonuclease involved in human NMD. However, Smg5 lacks several of these key catalytic residues and does not degrade single-stranded RNA, in vivo.

1218-1376 2.37e-06

VapC-like PIN domains of VapC and Smg6 ribonucleases, ribosome assembly factor NOB1, rRNA-processing protein Fcf1, Archaeoglobus fulgidus AF0591 protein, and homologs; PIN (PilT N terminus) domains of such ribonucleases as the toxins of prokaryotic toxin/antitoxin operons FitAB and VapBC, as well as, eukaryotic ribonucleases such as Smg6, ribosome assembly factor NOB1, exosome subunit Rrp44 endoribonuclease and rRNA-processing protein Fcf1, are included in VapC-like this family. Also included are the PIN domains of the Pyrobaculum aerophilum Pea0151 and Archaeoglobus fulgidus AF0591 proteins and other similar archaeal homologs. The PIN domain belongs to a large nuclease superfamily. The structural properties of the PIN domain indicate its active center, consisting of three highly conserved catalytic residues which coordinate metal ions; in some members, additional metal coordinating residues can be found while some others lack several of these key catalytic residues. The PIN active site is geometrically similar in the active center of structure-specific 5' nucleases, PIN-domain ribonucleases of eukaryotic rRNA editing proteins, and bacterial toxins of toxin-antitoxin (TA) operons.

VapC-like PIN domain of Archaeoglobus fulgidus AF0591 protein and other similar archaeal homologs; PIN (PilT N terminus) domain of Archaeoglobus fulgidus AF0591 protein and other similar uncharacterized archaeal homologs are included in this family. This subgroup belongs to the VapC (virulence-associated protein C)-like family of the PIN domain nuclease superfamily. VapC is the PIN-domain ribonuclease toxin from prokaryotic VapBC toxin-antitoxin (TA) systems. VapB is a transcription factor-like protein antitoxin acting as an inhibitor. Other members of the VapC-like nuclease family include FitB toxin of the FitAB TA system, eukaryotic ribonucleases such as Smg6, ribosome assembly factor NOB1, exosome subunit Rrp44 endoribonuclease and rRNA-processing protein Fcf1. The structural properties of the PIN (PilT N terminus) domain indicate its active center, consisting of three highly conserved catalytic residues which coordinate metal ions, in some members, additional metal coordinating residues can be found. Some members of the superfamily lack several of these key catalytic residues. PIN domains within this subgroup contain four of these highly conserved putative metal-binding, active site residues. The PIN active site is geometrically similar in the active center of structure-specific 5' nucleases, PIN-domain ribonucleases of eukaryotic rRNA editing proteins, and bacterial toxins of toxin-antitoxin (TA) operons. Matelska et al. recently classified PIN-like domains and included distant subgroups, this subgroup includes some sequences belonging to one of these, PIN_14.
