Summaries for TPP1 Gene

Entrez Gene Summary for TPP1 Gene

  • This gene encodes a member of the sedolisin family of serine proteases. The protease functions in the lysosome to cleave N-terminal tripeptides from substrates, and has weaker endopeptidase activity. It is synthesized as a catalytically-inactive enzyme which is activated and auto-proteolyzed upon acidification. Mutations in this gene result in late-infantile neuronal ceroid lipofuscinosis, which is associated with the failure to degrade specific neuropeptides and a subunit of ATP synthase in the lysosome. [provided by RefSeq, Jul 2008]

GeneCards Summary for TPP1 Gene

TPP1 (Tripeptidyl Peptidase 1) is a Protein Coding gene. Diseases associated with TPP1 include Ceroid Lipofuscinosis, Neuronal, 2 and Spinocerebellar Ataxia, Autosomal Recessive 7. Among its related pathways are Unfolded Protein Response (UPR) and Metabolism of proteins. Gene Ontology (GO) annotations related to this gene include serine-type endopeptidase activity and serine-type peptidase activity.

UniProtKB/Swiss-Prot for TPP1 Gene

  • 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).

  • Ceroid lipofuscinosis, neuronal, 2 (CLN2) [MIM: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. {ECO:0000269 PubMed:10330339, ECO:0000269 PubMed:10665500, ECO:0000269 PubMed:11241479, ECO:0000269 PubMed:11339651, ECO:0000269 PubMed:11589012, ECO:0000269 PubMed:12376936, ECO:0000269 PubMed:12414822, ECO:0000269 PubMed:12698559, ECO:0000269 PubMed:14736728, ECO:0000269 PubMed:19201763, ECO:0000269 PubMed:20340139, ECO:0000269 PubMed:21990111, ECO:0000269 PubMed:22612257, ECO:0000269 PubMed:9295267}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Spinocerebellar ataxia, autosomal recessive, 7 (SCAR7) [MIM:609270]: Spinocerebellar ataxia defines a clinically and genetically heterogeneous group of cerebellar disorders. Patients show progressive incoordination of gait and often poor coordination of hands, speech and eye movements, due to degeneration of the cerebellum with variable involvement of the brainstem and spinal cord. SCAR7 patients show difficulty walking and writing, dysarthria, limb ataxia, and cerebellar atrophy. {ECO:0000269 PubMed:23418007}. Note=The disease is caused by mutations affecting the gene represented in this entry.
