PPT1 - palmitoyl-protein thioesterase 1 Gene
Also Known as PPT; CLN1; INCL
Species: Homo sapiens
About PPT1
This gene has 19 transcripts (splice variants), 221 orthologues, 2 paralogues and is associated with 4 phenotypes. Ubiquitous expression in spleen (RPKM 86.1), lung (RPKM 62.1) and 25 other tissues.
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 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]
