Gene Gene information from NCBI Gene database.
Entrez ID 5538
Gene name Palmitoyl-protein thioesterase 1
Gene symbol PPT1
Synonyms (NCBI Gene)
CLN1INCLPPT
Chromosome 1
Chromosome location 1p34.2
Summary The protein encoded by this gene is a small glycoprotein involved in the catabolism of lipid-modified proteins during lysosomal degradation. The encoded enzyme removes thioester-linked fatty acyl groups such as palmitate from cysteine residues. Defects in
