Predicted to enable snoRNA binding activity. Acts upstream of or within cell population proliferation; maturation of SSU-rRNA from tricistronic rRNA transcript (SSU-rRNA, 5.8S rRNA, LSU-rRNA); and trophectodermal cell differentiation. Located in apical part of cell; cytoplasm; and nucleolus. Is expressed in several structures, including bone marrow; brain; early conceptus; and reproductive system. Orthologous to human BYSL (bystin like). [provided by Alliance of Genome Resources, Apr 2022]
