Predicted to be a structural constituent of ribosome. Predicted to be involved in cytoplasmic translation; maturation of SSU-rRNA; and ribosomal small subunit assembly. Predicted to be located in cytoplasmic side of rough endoplasmic reticulum membrane. Predicted to be part of cytosolic small ribosomal subunit and polysomal ribosome. Human ortholog(s) of this gene implicated in Diamond-Blackfan anemia 15 with mandibulofacial dysostosis. Is an ortholog of human RPS28 (ribosomal protein S28).
