Zinc Finger C4H2 Domain-Containing Protein (ZC4H2) is a protein with 224 amino acids. ZC4H2 is a member of the zinc finger domain-containing protein family. ZC4H2 contains a C4H2-type zinc finger and is thought to be involved in zinc ion binding. This protein has been detected as an autoantigen in hepatocellular carcinoma patients. ZC4H2 is a potential candidate for X-linked mental retardation.Alternative Names: Zinc Finger C4H2 Domain-Containing Protein, Hepatocellular Carcinoma-Associated Antigen 127, ZC4H2, HCA127, KIAA1166
