Predicted to be a structural constituent of ribosome. Predicted to be involved in mitochondrial translation. Predicted to be part of mitochondrial large ribosomal subunit. Predicted to be active in mitochondrial ribosome. Is expressed in several structures, including dorsal pharyngeal muscle primordium; embryonic/larval midgut; head mesoderm; larval muscle cell; and larval muscle system. Orthologous to human MRPL48 (mitochondrial ribosomal protein L48).
