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. : Pssm-ID: 350232 Cd Length: 160 Bit Score: 236.02 E-value: 2.50e-72

VapC-like PIN domain of nonsense-mediated decay (NMD) factors, Smg5 and Smg6, and related proteins; PIN (PilT N terminus) domain of nonsense-mediated decay (NMD) factors, Smg5 and Smg6, and homologs are included in this 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. 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. 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. Many of the bacterial homologs in this group have an N-terminal PIN domain and a C-terminal PhoH-like ATPase domain. Pssm-ID: 350228 Cd Length: 152 Bit Score: 108.53 E-value: 2.51e-27

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. Pssm-ID: 350233 Cd Length: 178 Bit Score: 69.98 E-value: 1.25e-13

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. 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.
