Record overview

LMPD IDLMP002384
Gene ID5538
SpeciesHomo sapiens (Human)
Gene Namepalmitoyl-protein thioesterase 1
Gene SymbolPPT1
SynonymsCLN1; INCL; PPT
Alternate namespalmitoyl-protein thioesterase 1; palmitoyl-protein hydrolase 1; ceroid-palmitoyl-palmitoyl-protein thioesterase 1
Chromosome1
Map Location1p32
EC Number3.1.2.22
SummaryThe 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 this gene are a cause of infantile neuronal ceroid lipofuscinosis 1 (CLN1, or INCL) and neuronal ceroid lipofuscinosis 4 (CLN4). Two transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Dec 2008]
