A PF00013 KH_1 KH domain Domain KH motifs bind RNA in vitro. Autoantibodies to Nova, a KH domain protein, cause paraneoplastic opsoclonus ataxia. PFAM PF00013
A PF01138 RNase_PH 3' exoribonuclease family, domain 1 Domain This family includes 3'-5' exoribonucleases. Ribonuclease PH contains a single copy of this domain, and removes nucleotide residues following the -CCA terminus of tRNA. Polyribonucleotide nucleotidyltransferase (PNPase) contains two tandem copies of the domain. PNPase is involved in mRNA degradation in a 3'-5' direction. The exosome is a 3'-5' exoribonuclease complex that is required for 3' processing of the 5.8S rRNA. Three of its five protein components, Swiss:P46948 Swiss:Q12277 and Swiss:P25359 contain a copy of this domain [1]. Swiss:Q10205, a hypothetical protein from S. pombe appears to belong to an uncharacterised subfamily. This subfamily is found in both eukaryotes and archaebacteria. PFAM PF01138
A PF03726 PNPase Polyribonucleotide nucleotidyltransferase, RNA binding domain Domain This family contains the RNA binding domain of Polyribonucleotide nucleotidyltransferase (PNPase) PNPase is involved in mRNA degradation in a 3'-5' direction. PFAM PF03726
A PF03725 RNase_PH_C 3' exoribonuclease family, domain 2 Domain This family includes 3'-5' exoribonucleases.
