40S ribosomal protein S3 is a protein that in humans is encoded by the RPS3 gene.Ribosomes the organelles that catalyze protein synthesis consist of a small 40S subunit and a large 60S subunit. Together these subunits are composed of 4 RNA species and approximately 80 structurally distinct proteins. This gene encodes a ribosomal protein that is a component of the 40S subunit where it forms part of the domain where translation is initiated.
