CC   -!- FUNCTION: Non-catalytic component of the exosome, which is a complex
CC       involved in RNA degradation. Contributes to the structuring of the
CC       Rrp41 active site. {ECO:0000255|HAMAP-Rule:MF_00622}.
CC   -!- SUBUNIT: Component of the archaeal exosome complex. Forms a hexameric
CC       ring-like arrangement composed of 3 Rrp41-Rrp42 heterodimers. The
CC       hexameric ring associates with a trimer of Rrp4 and/or Csl4 subunits.
CC       {ECO:0000255|HAMAP-Rule:MF_00622}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00622}.
CC   -!- SIMILARITY: Belongs to the RNase PH family. Rrp42 subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_00622}.
