Summaries for PPT1 Gene

Entrez Gene Summary for PPT1 Gene

  • 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 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]

GeneCards Summary for PPT1 Gene

PPT1 (Palmitoyl-Protein Thioesterase 1) is a Protein Coding gene. Diseases associated with PPT1 include neuronal ceroid-lipofuscinoses and ceroid lipofuscinosis, neuronal, 1. Among its related pathways are Metabolism and Lysosome. GO annotations related to this gene include palmitoyl-CoA hydrolase activity and palmitoyl hydrolase activity. An important paralog of this gene is PPT2.

  • Ceroid lipofuscinosis, neuronal, 1 (CLN1) [MIM:256730]: A form of neuronal ceroid lipofuscinosis with variable age at onset. Infantile, late-infantile, juvenile, and adult onset have been reported. Neuronal ceroid lipofuscinoses are progressive neurodegenerative, lysosomal storage diseases characterized by intracellular accumulation of autofluorescent liposomal material, and clinically by seizures, dementia, visual loss, and/or cerebral atrophy. The lipopigment pattern seen most often in CLN1 is referred to as granular osmiophilic deposits (GROD). {ECO:0000269 PubMed:11506414, ECO:0000269 PubMed:19201763, ECO:0000269 PubMed:21990111, ECO:0000269 PubMed:7637805, ECO:0000269 PubMed:9425237, ECO:0000269 PubMed:9664077}.
