Palmitoyltransferase that targets several endosomal SNAREs. Palmitoylates the SNAREs at cysteine residues close to the cytoplasmic end of their transmembrane domain. May have a role in the cellular quality control of transmembrane domain-containing proteins (By similarity). hexadecanoyl-CoA + L-cysteinyl-[protein] = CoA + S-hexadecanoyl-L-cysteinyl-[protein] The DHHC domain is required for palmitoyltransferase activity. Belongs to the DHHC palmitoyltransferase family. SWF1 subfamily.
