    Summary
    Predicted to enable rRNA binding activity. Predicted to be a structural constituent of ribosome. Involved in endonucleolytic cleavage in ITS1 to separate SSU-rRNA from 5.8S rRNA and LSU-rRNA from tricistronic rRNA transcript (SSU-rRNA, 5.8S rRNA, LSU-rRNA) and ribosomal subunit export from nucleus. Located in mitochondrion. Orthologous to human RPS18 (ribosomal protein S18). [provided by Alliance of Genome Resources, Dec 2024]
