S1_pNO40: pNO40 , S1-like RNA-binding domain. pNO40 is a nucleolar protein of unknown function with an N-terminal S1 RNA binding domain, a CCHC type zinc finger, and clusters of basic amino acids representing a potential nucleolar targeting signal. pNO40 was identified through a yeast two-hybrid interaction screen of a human kidney cDNA library using the pinin (pnn) protein as bait. pNO40 is thought to play a role in ribosome maturation and/or biogenesis.

ribosomal protein S1; This model describes ribosomal protein S1, RpsA. This protein is found in most bacterial genomes in a single copy, but is not present in the Mycoplasmas. It is heterogeneous with respect to the number of repeats of the S1 RNA binding domain described by pfam00575: six repeats in E. coli and most other bacteria, four in Bacillus subtilis and some other species. rpsA is an essential gene in E. coli but not in B. subtilis. It is associated with the cytidylate kinase gene cmk in many species, and fused to it in Treponema pallidum. RpsA is proposed (Medline:97323001) to assist in mRNA degradation. This model provides trusted hits to most long form (6 repeat) examples of RpsA. Among homologs with only four repeats are some to which other (perhaps secondary) functions have been assigned.

S1_DHX8_helicase: The N-terminal S1 domain of human ATP-dependent RNA helicase DHX8, a DEAH (Asp-Glu-Ala-His) box polypeptide. The DEAH-box RNA helicases are thought to play key roles in pre-mRNA splicing and DHX8 facilitates nuclear export of spliced mRNA by releasing the RNA from the spliceosome. DHX8 is also known as HRH1 (human RNA helicase 1) in Homo sapiens and PRP22 in Saccharomyces cerevisiae.

2-63 4.52e-13

S1_PNPase: Polynucleotide phosphorylase (PNPase), ), S1-like RNA-binding domain. PNPase is a polyribonucleotide nucleotidyl transferase that degrades mRNA. It is a trimeric multidomain protein. The C-terminus contains the S1 domain which binds ssRNA. This family is classified based on the S1 domain. PNPase nonspecifically removes the 3' nucleotides from mRNA, but is stalled by double-stranded RNA structures such as a stem-loop. Evidence shows that a minimum of 7-10 unpaired nucleotides at the 3' end, is required for PNPase degradation. It is suggested that PNPase also dephosphorylates the RNA 5' end. This additional activity may regulate the 5'-dependent activity of RNaseE in vivo.

S1_RPS1_repeat_hs4: Ribosomal protein S1 (RPS1) domain. RPS1 is a component of the small ribosomal subunit thought to be involved in the recognition and binding of mRNA's during translation initiation. The bacterial RPS1 domain architecture consists of 4-6 tandem S1 domains. In some bacteria, the tandem S1 array is located C-terminal to a 4-hydroxy-3-methylbut-2-enyl diphosphate reductase (HMBPP reductase) domain. While RPS1 is found primarily in bacteria, proteins with tandem RPS1-like domains have been identified in plants and humans, however these lack the N-terminal HMBPP reductase domain. This CD includes S1 repeat 4 (hs4) of the H. sapiens RPS1 homolog. Autoantibodies to double-stranded DNA from patients with systemic lupus erythematosus cross-react with the human RPS1 homolog.

S1_Tex: The C-terminal S1 domain of a transcription accessory factor called Tex, which has been characterized in Bordetella pertussis and Pseudomonas aeruginosa. The tex gene is essential in Bortella pertusis and is named for its role in toxin expression. Tex has two functional domains, an N-terminal domain homologous to the Escherichia coli maltose repression protein, which is a poorly defined transcriptional factor, and a C-terminal S1 RNA-binding domain. Tex is found in prokaryotes, eukaryotes, and archaea.

2-64 2.32e-09

S1_Rrp5_repeat_sc12: Rrp5 is a trans-acting factor important for biogenesis of both the 40S and 60S eukaryotic ribosomal subunits. Rrp5 has two distinct regions, an N-terminal region containing tandemly repeated S1 RNA-binding domains (12 S1 repeats in Saccharomyces cerevisiae Rrp5 and 14 S1 repeats in Homo sapiens Rrp5) and a C-terminal region containing tetratricopeptide repeat (TPR) motifs thought to be involved in protein-protein interactions. Mutational studies have shown that each region represents a specific functional domain. Deletions within the S1-containing region inhibit pre-rRNA processing at either site A3 or A2, whereas deletions within the TPR region confer an inability to support cleavage of A0-A2. This CD includes S. cerevisiae S1 repeat 12 (sc12). Rrp5 is found in eukaryotes but not in prokaryotes or archaea.

S1_RPS1_repeat_ec5: Ribosomal protein S1 (RPS1) domain. RPS1 is a component of the small ribosomal subunit thought to be involved in the recognition and binding of mRNA's during translation initiation. The bacterial RPS1 domain architecture consists of 4-6 tandem S1 domains. In some bacteria, the tandem S1 array is located C-terminal to a 4-hydroxy-3-methylbut-2-enyl diphosphate reductase (HMBPP reductase) domain. While RPS1 is found primarily in bacteria, proteins with tandem RPS1-like domains have been identified in plants and humans, however these lack the N-terminal HMBPP reductase domain. This CD includes S1 repeat 5 (ec5) of the Escherichia coli RPS1. Autoantibodies to double-stranded DNA from patients with systemic lupus erythematosus cross-react with the human RPS1 homolog.
