Predicted to enable mRNA binding activity and rRNA binding activity. Predicted to be a structural constituent of ribosome. Predicted to be involved in mitochondrial translation and ribosomal small subunit assembly. Predicted to be part of mitochondrial small ribosomal subunit. Predicted to be active in ribosome. Is expressed in several structures, including adult head; adult heart; embryonic/larval midgut primordium; gut section; and larval muscle cell. Human ortholog(s) of this gene implicated in combined oxidative phosphorylation deficiency 34. Orthologous to human MRPS7 (mitochondrial ribosomal protein S7).
