RPSBLAST alignment for GI: 254780784 and conserved domain: pfam01138

>gnl|CDD|144653 pfam01138, RNase_PH, 3' exoribonuclease family, domain 1. 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 contain a copy of this domain. A hypothetical protein from S. pombe appears to belong to an uncharacterized subfamily. This subfamily is found in both eukaryotes and archaebacteria. Length = 128
 Score =  115 bits (291), Expect = 3e-26
 Identities = 47/132 (35%), Positives = 62/132 (46%), Gaps = 6/132 (4%)
