    Summary
    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 endonucleolytic cleavage to generate mature 3'-end of SSU-rRNA from (SSU-rRNA, 5.8S rRNA, LSU-rRNA). Part of cytosolic small ribosomal subunit. Orthologous to human RPS21 (ribosomal protein S21). [provided by Alliance of Genome Resources, Dec 2024]
