CC -!- FUNCTION: GTPase involved in the biogenesis of the 60S ribosomal
CC subunit and translational activation of ribosomes. Together with sdo1,
CC may trigger the GTP-dependent release of tif6 from 60S pre-ribosomes in
CC the cytoplasm, thereby activating ribosomes for translation competence
CC by allowing 80S ribosome assembly and facilitating tif6 recycling to
CC the nucleus, where it is required for 60S rRNA processing and nuclear
CC export. Inhibits GTPase activity of ribosome-bound EF-2 (By
CC similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=GTP + H2O = GDP + H(+) + phosphate; Xref=Rhea:RHEA:19669,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:37565,
CC ChEBI:CHEBI:43474, ChEBI:CHEBI:58189;
CC -!- ACTIVITY REGULATION: GTPase activity is stimulated in the presence of
CC 60S subunits. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000269|PubMed:16823372}.
CC -!- SIMILARITY: Belongs to the TRAFAC class translation factor GTPase
CC superfamily. Classic translation factor GTPase family.
CC {ECO:0000255|PROSITE-ProRule:PRU01059}.
