CC -!- FUNCTION: Small GTPase required for proper localization of RNA
CC polymerase II and III (RNAPII and RNAPIII). May act at an RNAP assembly
CC step prior to nuclear import. {ECO:0000250|UniProtKB:Q08726}.
CC -!- SUBUNIT: Heterodimers with GPN1 or GPN3. Binds to RNA polymerase II
CC (RNAPII). {ECO:0000250|UniProtKB:Q08726, ECO:0000250|UniProtKB:Q9H9Y4}.
CC -!- SIMILARITY: Belongs to the GPN-loop GTPase family. {ECO:0000305}.
