Anti-MRP4 antibodies enable researchers to detect and measure the MRP4 antigen in biological samples. This target is a reported synonym of the ABCC4 gene, which encodes ATP binding cassette subfamily C member 4. This protein is known to function in cilium assembly and transmembrane transport, among other biological roles. The human version of MRP4 has a canonical amino acid length of 1325 residues and a protein mass of 149.5 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the cell membrane of cells and notably expressed in the prostate, fallopian tube, colon, and cerebral cortex. Other names for this target antigen include MOAT-B and MOATB. Some MRP4 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
