Golgi-localized palmitoyltransferase that catalyzes the addition of palmitate onto various protein substrates and regulates their association with membranes (Probable). Has no stringent fatty acid selectivity and in addition to palmitate can also transfer onto target proteins myristate from tetradecanoyl-CoA and stearate from octadecanoyl-CoA (Probable). hexadecanoyl-CoA + L-cysteinyl-[protein] = CoA + S-hexadecanoyl-L-cysteinyl-[protein] L-cysteinyl-[protein] + tetradecanoyl-CoA = CoA + S-tetradecanoyl-L-cysteinyl-[protein] L-cysteinyl-[protein] + octadecanoyl-CoA = CoA + S-octadecanoyl-L-cysteinyl-[protein] Monomer. Homooligomers. The monomeric form has a higher catalytic activity. Forms heterooligomers with zdhhc7. Probably maternally supplied, the zygotic expression is detected early during development at the sphere stage but decreases after 7.5 hpf. The DHHC domain is required for palmitoyltransferase activity. Autopalmitoylated. Belongs to the DHHC palmitoyltransferase family.
