Predicted to enable ribosomal large subunit binding activity. Predicted to be involved in negative regulation of mitochondrial translation; negative regulation of ribosome biogenesis; and ribosomal large subunit biogenesis. Predicted to act upstream of or within ribosome biogenesis. Predicted to be located in cytosol. Predicted to be part of mitochondrial large ribosomal subunit. Predicted to be active in mitochondrion. Orthologous to human MALSU1 (mitochondrial assembly of ribosomal large subunit 1). [provided by Alliance of Genome Resources, Apr 2022]
