CC   -!- FUNCTION: Small GTPase required for proper nuclear import 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:Q06543}.
CC   -!- SUBUNIT: Heterodimers with GPN1 or GPN2. Binds to RNA polymerase II
CC       (RNAPII). {ECO:0000250|UniProtKB:Q06543}.
CC   -!- SIMILARITY: Belongs to the GPN-loop GTPase family. {ECO:0000305}.
