Anti-MRX91 antibodies enable researchers to detect and measure the MRX91 antigen in biological samples. This target is a reported synonym of the ZDHHC15 gene, which encodes zinc finger DHHC-type palmitoyltransferase 15. This protein is a reported palmitoyltransferase that catalyzes the addition of palmitate onto various protein substrates. The human version of MRX91 has a canonical amino acid length of 337 residues and a protein mass of 39.3 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the Golgi of cells and widely expressed in many tissue types. MRX91 is a member of the DHHC palmitoyltransferase protein family.
