Anti-HHRH antibodies enable researchers to detect and measure the HHRH antigen in biological samples. This target is a reported synonym of the SLC34A3 gene, which encodes solute carrier family 34 member 3. This protein is known to function in the transport of ions, among other biological roles. The human version of HHRH has a canonical amino acid length of 599 residues and a protein mass of 63.6 kilodaltons. It is reported to be localized in the cell membrane of cells and notably expressed in the kidney. HHRH is a member of the SLC34A transporter protein family.
