Predicted to enable protein homodimerization activity and protein-cysteine S-palmitoyltransferase activity. Predicted to be involved in several processes, including peptidyl-L-cysteine S-palmitoylation; positive regulation of GABAergic synaptic transmission; and protein localization to membrane. Predicted to act upstream of or within protein palmitoylation and protein targeting. Located in Golgi apparatus. Orthologous to human ZDHHC3 (zinc finger DHHC-type palmitoyltransferase 3).
