[[ | [[https://www.uniprot.org/uniprot/TPP1_HUMAN TPP1_HUMAN]] Defects in TPP1 are the cause of neuronal ceroid lipofuscinosis type 2 (CLN2) [MIM:[https://omim.org/entry/204500 204500]]. A form of neuronal ceroid lipofuscinosis. 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 CLN2 consists of curvilinear profiles.<ref>PMID:9295267</ref> <ref>PMID:10330339</ref> <ref>PMID:10665500</ref> <ref>PMID:11339651</ref> <ref>PMID:11241479</ref> <ref>PMID:11589012</ref> <ref>PMID:12376936</ref> <ref>PMID:12414822</ref> <ref>PMID:12698559</ref> <ref>PMID:14736728</ref> <ref>PMID:19201763</ref> <ref>PMID:20340139</ref> <ref>PMID:21990111</ref> | ||

[[ | [[https://www.uniprot.org/uniprot/TPP1_HUMAN TPP1_HUMAN]] Lysosomal serine protease with tripeptidyl-peptidase I activity. May act as a non-specific lysosomal peptidase which generates tripeptides from the breakdown products produced by lysosomal proteinases. Requires substrates with an unsubstituted N-terminus (By similarity). | ||
