General annotation (Comments)

Function

Removes thioester-linked fatty acyl groups such as palmitate from modified cysteine residues in proteins or peptides during lysosomal degradation. Prefers acyl chain lengths of 14 to 18 carbons.

Catalytic activity

Palmitoyl-protein + H2O = palmitate + protein.

Subcellular location

Lysosome. Ref.3

Tissue specificity

Spleen, brain, seminal vesicle, and testis. Lower levels of activity in liver, heart, lung, and skeletal muscle.

Sequence similarities

Belongs to the palmitoyl-protein thioesterase family.
