RPS3A is a member of the S3AE family of ribosomal proteins. Ribosomes, the organelles which catalyze protein synthesis, composed of a large 60S subunit and a small 40S subunit. Together these subunits consist of 4 RNA classes and around 80 structurally diverse proteins. RPS3A, a component of the 40S subunit, is a ribosomal protein that is situated in the cytoplasm. Interference of the gene encoding rat ribosomal protein S3a, in v-fos-transformed rat cells cause a degeneration of the transformed phenotype.

RPS3A Human Recombinant produced in E. coli is a single polypeptide chain containing 288 amino acids (1-264) and having a molecular mass of 32.5kDa.
RPS3A is fused to a 24 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.

The RPS3A solution (0.5mg/ml) contains 20mM Tris-HCl buffer (pH 8.0), 200mM NaCl, 2mM DTT and 50% glycerol.
