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.

S1_CSL4: CSL4, S1-like RNA-binding domain. S1-like RNA-binding domains are found in a wide variety of RNA-associated proteins. ScCSL4 protein is a subunit of the exosome complex. The exosome plays a central role in 3' to 5' RNA processing and degradation in eukarytes and archaea. Its functions include the removal of incorrectly processed RNA and the maintenance of proper levels of mRNA, rRNA and a number of small RNA species. In S. cerevisiae, the exosome includes nine core components, six of which are homologous to bacterial RNase PH. These form a hexameric ring structure. The other three subunits (RrP4, Rrp40, and Csl4) contain an S1 RNA binding domain and are part of the "S1 pore structure".
