Anti-zinc finger CCCH-type, antiviral 1 antibodies enable researchers to detect and measure the zinc finger CCCH-type, antiviral 1 antigen in biological samples. This target is a reported synonym of the ZC3HAV1 gene, which encodes zinc finger CCCH-type containing, antiviral 1. This protein is known to function in innate immune responses, among other biological roles. The human version of zinc finger CCCH-type, antiviral 1 has a canonical amino acid length of 902 residues and a protein mass of 101.4 kilodaltons, although 5 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells and widely expressed in many tissue types. Other names for this target antigen include zinc finger CCCH-type antiviral protein 1, ADP-ribosyltransferase diphtheria toxin-like 13, and inactive Poly [ADP-ribose] polymerase 13.
