40S ribosomal protein S4 X isoform is a protein that in humans is encoded by the RPS4X gene.Cytoplasmic ribosomes 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 ribosomal protein S4 a component of the 40S subunit.
