A structural constituent of ribosome. Predicted to be involved in translation. Located in cytoplasm. Part of cytosolic small ribosomal subunit. Orthologous to human RPS4X (ribosomal protein S4 X-linked); RPS4Y1 (ribosomal protein S4 Y-linked 1); and RPS4Y2 (ribosomal protein S4 Y-linked 2).
SGD Description
Protein component of the small (40S) ribosomal subunit; mutation affects 20S pre-rRNA processing; homologous to mammalian ribosomal protein S4, no bacterial homolog; RPS4A has a paralog, RPS4B, that arose from the whole genome duplication
