S1_like: Ribosomal protein S1-like RNA-binding domain. Found in a wide variety of RNA-associated proteins. Originally identified in S1 ribosomal protein. This superfamily also contains the Cold Shock Domain (CSD), which is a homolog of the S1 domain. Both domains are members of the Oligonucleotide/oligosaccharide Binding (OB) fold.


The actual alignment was detected with superfamily member cd05686:

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.

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.

 5-39 3.87e-05

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_ec3: 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 3 (ec3) of the Escherichia coli RPS1. Autoantibodies to double-stranded DNA from patients with systemic lupus erythematosus cross-react with the human RPS1 homolog.
