RNA-binding protein NOB1 [Homo sapiens]
NOB1 family endonuclease( domain architecture ID 12182058)
uncharacterized NOB1 (nin one binding) family endonuclease similar to Numida meleagris NOB1, and to Saccharomyces cerevisiae endonuclease NOB1 which is required for cleavage of the 20S pre-RNA at its 3' end (the D-site) to yield the mature 18S RNA

7-93 | 7.42e-48 | |||
PIN domain of ribonuclease; This is a PIN domain found in eukaryotic ribonuclease Nob1 and archaeal ribonuclease VapC1. Budding yeast Nob1 is involved in proteasomal and 40S ribosomal subunit biogenesis. VapC1 is a toxic component and a ribonuclease of a toxin-antitoxin (TA) module. PIN domains are small protein domains identified by the presence of three strictly conserved acidic residues. Apart from these three residues, there is poor sequence conservation. PIN domains are found in eukaryotes, eubacteria and archaea. In eukaryotes they are ribonucleases involved in nonsense mediated mRNA decay and in processing of 18S ribosomal RNA. In prokaryotes, they are the toxic components of toxin-antitoxin (TA) systems, their toxicity arising by virtue of their ribonuclease activity. The PIN domain TA systems are now called VapBC TAs(virulence associated proteins), where VapB is the inhibitor and VapC, the PIN-domain ribonuclease toxin. : Pssm-ID: 465362 Cd Length: 87 Bit Score: 157.95 E-value: 7.42e-48

152-212 | 8.96e-14 | |||
Putative WW-binding domain and destruction box; This short conserved region is a putative destruction-box, with its RxxLxxI sequence motif, though the homology is not absolute. The domain occurs on a number of tumourigenic proteins, on some RNA-binding proteins and serine-threonine regulatory proteins. The second less well-conserved motif, WITPS, is a potential WW domain ligand-binding motif for recruiting proteins to their substrates. WW domains bind tightly to short proline-containing peptides that are typically in regions of native disordered polypeptide, as this family is as it lies between a PIN domain and a zinc-binding domain. : Pssm-ID: 464448 Cd Length: 56 Bit Score: 65.44 E-value: 8.96e-14

7-109 | 3.37e-47 | |||
VapC-like PIN domain of eukaryotic ribosome assembly factor Nob1 and archaeal UPF0129 protein Ta0041-like homologs; PIN (PilT N terminus) domain of the Saccharomyces cerevisiae ribosome assembly factor, Nob1 (Nin one binding) protein, the Thermoplasma acidophilum DSM 1728, UPF0129 protein Ta0041, and similar eukaryotic and archaeal homologs are included in this family. The Nob1 PIN domain binds the single-stranded cleavage site D at the 3-prime end of 18S rRNA. Recombinant Nob1 binds as a tetramer to pre-18S rRNA fragments containing cleavage site D and believed to cleave at this site. 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 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. Matelska et al. recently classified PIN-like domains into distinct groups; this subgroup includes some sequences belonging to one of these, PIN_6.
