Background： 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.

Function：catalytic activity:Release of an N-terminal tripeptide from a polypeptide, but also has endopeptidase activity.,caution:Ref.3 sequence is wrongly reported to originate from bovine.,disease:Defects in TPP1 are the cause of classical late-infantile neuronal ceroid lipofuscinosis (LINCL) [MIM:204500]; also known as ceroid lipofuscinosis neuronal 2 (CLN2). LINCL is a fatal childhood neurodegenerative disease characterized by progressive visual and mental decline, motor disturbance, epilepsy and behavioral changes. The three main subtypes of childhood NCLs defined by the age of onset, clinical features, and ultrastructural morphology are infantile NCL (INCL), classical late-infantile NCL (LINCL), or juvenile NCL (JNCL), although a number of other distinct variants forms have been described.,function:Lysosomal serine protease with tripeptidyl-peptidase I activity. May act as a non-specific lys

Subcellular Location：Lysosome . Melanosome . Identified by mass spectrometry in melanosome fractions from stage I to stage IV. .

Expression：Detected in all tissues examined with highest levels in heart and placenta and relatively similar levels in other tissues.
