Palmitoyltransferase that could catalyze the addition of palmitate onto various protein substrates (By similarity). Palmitoyltransferase for HTT and GAD2. May play a role in Mg(2+) transport.
Subcellular locations: Golgi apparatus membrane, Cytoplasmic vesicle membrane
Low extracellular Mg(2+) induces increase in Golgi and in post-Golgi vesicles.
