CC   -!- FUNCTION: Non-catalytic component of the exosome, which is a complex
CC       involved in RNA degradation. Increases the RNA binding and the
CC       efficiency of RNA degradation. Confers strong poly(A) specificity to
CC       the exosome. {ECO:0000255|HAMAP-Rule:MF_00623}.
CC   -!- SUBUNIT: Component of the archaeal exosome complex. Forms a trimer of
CC       Rrp4 and/or Csl4 subunits. The trimer associates with a hexameric ring-
CC       like arrangement composed of 3 Rrp41-Rrp42 heterodimers.
CC       {ECO:0000255|HAMAP-Rule:MF_00623}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00623}.
CC   -!- SIMILARITY: Belongs to the RRP4 family. {ECO:0000255|HAMAP-
CC       Rule:MF_00623}.
