This is a PIN domain found in eukaryotic ribonuclease Nob1 and archaeal ribonuclease VapC1 [1]. Budding yeast Nob1 is involved in proteasomal and 40S ribosomal subunit biogenesis [2]. VapC1 is a toxic component and a ribonuclease of a toxin-antitoxin (TA) module [3]. 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 [4]. PIN domains are found in eukaryotes, eubacteria and archaea. In eukaryotes they are ribonucleases involved in nonsense mediated mRNA decay [5] and in processing of 18S ribosomal RNA [6]. 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 [4].
This family contains a central domain Pfam:PF00013, hence the amino and carboxyl terminal domains are stored separately. This is a minimal carboxyl-terminal domain. Some are much longer.
The S4 domain is a small domain consisting of 60-65 amino acid residues that was detected in the bacterial ribosomal protein S4, eukaryotic ribosomal S9, two families of pseudouridine synthases, a novel family of predicted RNA methylases, a yeast pro ...
The S4 domain is a small domain consisting of 60-65 amino acid residues that was detected in the bacterial ribosomal protein S4, eukaryotic ribosomal S9, two families of pseudouridine synthases, a novel family of predicted RNA methylases, a yeast protein containing a pseudouridine synthetase and a deaminase domain, bacterial tyrosyl-tRNA synthetases, and a number of uncharacterized, small proteins that may be involved in translation regulation [1]. The S4 domain probably mediates binding to RNA.
This entry represents the first KH domain in the KRR1 protein [1]. Krr1 is a ribosomal assembly factor. The KH1 domain is a divergent KH domain that lacks the RNA-binding GXXG motif and is involved in binding another assembly factor, Kri1 [1].
Eukaryotic type KH-domain (KH-domain type I) (327.11.2)
This entry represents the second KH domain found in the PNO1 protein. PNO1 is part of the small subunit (SSU) processome, first precursor of the small eukaryotic ribosomal subunit.

Members of this family are found in Rio2, and are structurally homologous to the winged helix (wHTH) domain. They adopt a structure consisting of four alpha helices followed by two beta strands and a fifth alpha helix. The domain confers DNA binding ...
Members of this family are found in Rio2, and are structurally homologous to the winged helix (wHTH) domain. They adopt a structure consisting of four alpha helices followed by two beta strands and a fifth alpha helix. The domain confers DNA binding properties to the protein, as per other winged helix domains [1].

This entry represents the G-like (guanine nucleotide-binding domain) domain, found in Tsr1, a protein required for normal export of the pre-40S particles from the nucleus to the cytoplasm during 40S ribosomal subunit synthesis [1-5]. This domain adopts a GTPase-like fold, but lacks a P-loop and is not predicted to bind GTP.
