Ribosomes （the organelles that catalyze protein synthesis） consist of a small 40S subunit and a large 60S subunit. Jointly these subunits are composed of 4 RNA species and approximately 80 structurally distinct proteins. RPS10 which is is located in the cytoplasm and a part of the S10E family of ribosomal proteins， is a ribosomal protein that is a component of the 40S subunit. Variable expression of this gene in colorectal cancers compared to adjacent normal tissues has been observed， although no correlation between the level of expression and the severity of the disease has been found.
