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.
