Predicted to enable protein heterodimerization activity and rRNA (guanine) methyltransferase activity. Predicted to be involved in positive regulation of rRNA processing and rRNA (guanine-N7)-methylation. Predicted to act upstream of or within chromatin organization; methylation; and rRNA processing. Predicted to be located in nucleoplasm and perinuclear region of cytoplasm. Predicted to be active in nucleolus. Human ortholog(s) of this gene implicated in Williams-Beuren syndrome. Orthologous to human BUD23 (BUD23 rRNA methyltransferase and ribosome maturation factor). [provided by Alliance of Genome Resources, Apr 2022]
