Palmitoyltransferase that could catalyze the addition of palmitate onto various protein substrates. The ZDHHC9-GOLGA7 complex is a palmitoyltransferase specific for HRAS and NRAS. May have a palmitoyltransferase activity toward the beta-2 adrenergic receptor/ADRB2 and therefore regulate G protein-coupled receptor signaling. hexadecanoyl-CoA + L-cysteinyl-[protein] = CoA + S-hexadecanoyl-L-cysteinyl-[protein] Interacts with GOLGA7. The DHHC domain is required for palmitoyltransferase activity. Belongs to the DHHC palmitoyltransferase family. ERF2/ZDHHC9 subfamily.
