Predicted to enable ATPase binding activity; TFIID-class transcription factor complex binding activity; and snoRNA binding activity. Predicted to be involved in snoRNA localization. Predicted to act upstream of or within ribosome biogenesis. Predicted to be located in Cajal body; cytosol; and fibrillar center. Predicted to be part of box C/D RNP complex; pre-snoRNP complex; and small-subunit processome. Is expressed in brain; embryo; eye; heart; and pancreas epithelium. Orthologous to human NOP58 (NOP58 ribonucleoprotein). [provided by Alliance of Genome Resources, Apr 2022]
