Palmitoyl-Protein Thioesterase 1 (PPT1) Protein, Linked to Neuronal Ceroid Lipofuscinosis 1, Is a Major Constituent of Ageing-Related Human Neuronal Lipofuscin.

ABSTRACT: Proteomics of laser-dissected lipofuscin from aged, healthy brains reveals Palmitoyl-Protein Thioesterase 1 (PPT1) and other CLN proteins as constituents. PPT1 is increasingly sequestered to lipofuscin during ageing. Protein sequestering into lipofuscin may contribute to physiological neuronal ageing.
