Involved in the biogenesis of the 60S ribosomal subunit (By similarity). Has a role in regulating longevity, growth and brood size (PubMed:24552710). May regulate fat storage via the insulin/IGF pathway (PubMed:24552710). Ubiquitously expressed. Expressed from early embryonic stages through to adulthood. RNAi-mediated knockdown results in an extended lifespan, reduced brood size, slower growth rate and increased fat storage. Belongs to the TRAFAC class OBG-HflX-like GTPase superfamily. OBG GTPase family. NOG subfamily.
