Anti-MRPS4 antibodies enable researchers to detect and measure the MRPS4 antigen in biological samples. This target is a reported synonym of the IMP3 gene, which encodes IMP U3 small nucleolar ribonucleoprotein 3. This protein is known to function in rRNA processing, among other biological roles. The human version of MRPS4 has a canonical amino acid length of 184 residues and a protein mass of 21.9 kilodaltons. It is reported to be localized in the nucleus of cells. Other names for this target antigen include BRMS2 and C15orf12.
