Predicted to enable GTP binding activity. Predicted to be involved in several processes, including negative regulation of protein modification by small protein conjugation or removal; negative regulation of telomere maintenance via telomerase; and positive regulation of protein localization to chromosome, telomeric region. Predicted to act upstream of or within ribosome biogenesis. Predicted to be located in cytosol and nucleoplasm. Predicted to be part of telomerase holoenzyme complex. Predicted to be active in nucleolus. Orthologous to human GNL3L (G protein nucleolar 3 like). [provided by Alliance of Genome Resources, Apr 2022]
