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, Nov 2024]

Preferred Names
ribosomal 40S subunit protein S18B
NP_013686.1
  • Protein component of the small (40S) ribosomal subunit; homologous to mammalian ribosomal protein S18 and bacterial S13; RPS18B has a paralog, RPS18A, that arose from the whole genome duplication; protein abundance increases in response to DNA replication stress
