palmitoyl-protein thioesterase 1 Show summary »

Target Id 3199
Nomenclature palmitoyl-protein thioesterase 1
Genes PPT1 (Hs), Ppt1 (Mm), Ppt1 (Rn)
Ensembl ID ENSG00000131238 (Hs), ENSMUSG00000028657 (Mm), ENSRNOG00000012616 (Rn)
EC number
Removes thioester-linked fatty acyl groups (e.g. palmitate) from modified cysteine residues in proteins/peptides during lysosomal degradation. Prefers acyl chain lengths of 14-18 carbons H2O + S-hexadecanoyl-L-cysteinyl-[protein] = H+ + hexadecanoate + L-cysteinyl-[protein] [3]
ezurpimtrostat [2]
Comment Involved in the catabolism of lipid-modified proteins during lysosomal degradation and autophagy. Inhibitors of PPT1 enzyme activity disrupt lysosomal function and autophagy, and are being examined for antitumour potential [2] and antiviral activity against SARS-CoV-2 [1].
