The RNA exosome complex is responsible for degrading RNA molecules in the 3' to 5' direction. Rrp40 is a 'cap' protein and binds the RNase PH barrel on the opposite side from the S1/KH ring. The N-terminal domain of Rrp44 forms a long beta-hairpin that is wedged in between Rrp41-Rrp42 and approaches the N terminus of the cap protein Rrp4 [1]. This domain adopts a beta- sandwich hybrid structure.

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.

The RNA exosome complex is responsible for degrading RNA molecules in the 3' to 5' direction. Rrp40 is a 'cap' protein and binds the RNase PH barrel on the opposite side from the S1/KH ring. The N-terminal domain of Rrp44 forms a long beta-hairpin that is wedged in between Rrp41-Rrp42 and approaches the N terminus of the cap protein Rrp4 [1]. This domain adopts a beta- sandwich hybrid structure.
