Anti-HKE3 antibodies enable researchers to detect and measure the HKE3 antigen in biological samples. This target is a reported synonym of the RPS18 gene, which encodes ribosomal protein S18. This protein is known to function in protein translation, among other biological roles. The human version of HKE3 has a canonical amino acid length of 152 residues and a protein mass of 17.7 kilodaltons. It is reported to be localized in the cytoplasm of cells and widely expressed in many tissue types. Other names for this target antigen include D6S218E and KE-3.
