Anti-DHHC18 antibodies enable researchers to detect and measure the DHHC18 antigen in biological samples. This target is a reported synonym of the ZDHHC18 gene, which encodes zinc finger DHHC-type palmitoyltransferase 18. This protein is known to function in innate immune responses, among other biological roles. The human version of DHHC18 has a canonical amino acid length of 388 residues and a protein mass of 42 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the Golgi of cells and widely expressed in many tissue types. DHHC18 is a member of the DHHC palmitoyltransferase protein family.
