Predicted to be involved in maturation of 5.8S rRNA and maturation of LSU-rRNA. Predicted to act upstream of or within rRNA processing. Predicted to be located in nucleus. Predicted to be part of preribosome, large subunit precursor. Is expressed in several structures, including branchial arch; extraembryonic ectoderm; neural ectoderm; and trunk mesenchyme. Orthologous to human NSA2 (NSA2 ribosome biogenesis factor). [provided by Alliance of Genome Resources, Apr 2022]
