Palmitoyltransferase that catalyzes the addition of palmitate onto various protein substrates (PubMed:36586411). Has a palmitoyltransferase activity toward gephyrin/GPHN, regulating its clustering at synapses and its function in gamma-aminobutyric acid receptor clustering (By similarity). Thereby, indirectly regulates GABAergic synaptic transmission (By similarity). Acts as an inhibitor of the NLRP3 inflammasome by mediating palmitoylation of NLRP3, thereby promoting NLRP3 degradation by the chaperone-mediated autophagy (CMA) process (PubMed:36586411).
