Function

edit

PPT-1 a member of the palmitoyl protein thioesterase family. PPT-1 is a small glycoprotein involved in the catabolism of lipid-modified proteins during lysosomal degradation. This enzyme removes thioester-linked fatty acyl groups such as palmitate from cysteine residues.[5]

Clinical significance

edit

Defects in this gene are a cause of neuronal ceroid lipofuscinosis type 1 (CLN1).[8]
