Protein attributes

Sequence length	336 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Palmitoyltransferase specific for VAC8. Palmitoylates VAC8 at one or more of its N-terminal cysteine residues, which is required for its proper membrane localization. Ref.6
Catalytic activity	Palmitoyl-CoA + protein-cysteine = S-palmitoyl protein + CoA.
Subcellular location	Vacuole membrane; Multi-pass membrane protein Ref.4 Ref.6.
Domain	The DHHC domain is required for palmitoyltransferase activity.
Post-translational modification	Autopalmitoylated.
Miscellaneous	Present with 2133 molecules/cell in log phase SD medium.
Sequence similarities	Belongs to the DHHC palmitoyltransferase family. PFA3 subfamily. Contains 1 DHHC-type zinc finger.
