Background: Tripeptidyl-Peptidase I/TPP1

Tripeptidyl-Peptidase I (TPP1), also known as tripeptidyl aminopeptidase, is a lysosomal peptidase which can hydrolyze tripeptides from the N-termini of oligopeptides and also possesses weak endopeptidase activity (1‑3). TPP1 is a serine peptidase with a Ser-Glu-Asp catalytic triad, making it a member of the sedolisin family (4). The TPP1 precursor undergoes autoactivation under conditions of acidic pH (4). TPP1 is expressed in many tissues, with elevated expression in tissues associated with peptide hormone production (5). Mutations in TPP1 have been shown to be a cause of classic late‑infantile neuronal ceroid lipofuscinosis (CLN2), a lysosomal storage disease (6).
