RA Jay Z.J., Rusch D.B., Tringe S.G., Bailey C., Jennings R.M., Inskeep W.P.;
RT "Predominant Acidilobus-like populations from geothermal environments of
RT Yellowstone National Park exhibit similar metabolic potential in different
RT hypoxic microbial communities.";
RL Submitted (OCT-2013) to the EMBL/GenBank/DDBJ databases.
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:0000256|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 an hexameric
CC ring-like arrangement composed of 3 Rrp41-Rrp42 heterodimers.
CC {ECO:0000256|HAMAP-Rule:MF_00623}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00623}.
CC Nucleus, nucleolus {ECO:0000256|ARBA:ARBA00004604}.
CC -!- SIMILARITY: Belongs to the RRP4 family. {ECO:0000256|ARBA:ARBA00009155,
CC ECO:0000256|HAMAP-Rule:MF_00623}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:ESQ22968.1}.
