What is/are Tripeptidyl Peptidase?

Tripeptidyl Peptidase - Results Enzymatic analysis of palmitoyl protein thioesterase 1 (PPT1)and tripeptidyl peptidase 1(TPP1) enzymes was within normal level in the four patients. [1] In humans, homozygous mutations in the TPP1 gene results in loss of tripeptidyl peptidase 1 (TPP1) enzymatic activity, leading to late infantile neuronal ceroid lipofuscinoses disease. [2] Tripeptidyl peptidase-1 offered a predictive value for outcome, with an area under a ROC curve of 84. [3] The serine aminopeptidase, tripeptidyl peptidase 1 (TPP1), was detected by proteomic analysis of cyst fluid samples and quantitation using targeted MS demonstrated that this protease was significantly more abundant in mucinous cysts. [4] Six compounds enhanced mitochondrial transport in the sub-micromolar range, acting via three cellular targets: F-actin, Tripeptidyl peptidase 1 (TPP1), or Aurora Kinase B (AurKB). [5] We created multiple cell lines each with different levels of reduction of expression of the gene coding for the type 2 variant of the disease, Tripeptidyl peptidase (Tpp1), in the cellular slime mould Dictyostelium discoideum. [6] Abundant proteinases (dipeptidase, dipeptidyl aminopeptidase, puromycin-sensitive aminopeptidase, Xaa-pro aminopeptidase, neutral protease 2 and leucine aminopeptidase 2), along with the glycoside hydrolase (glycoamylase, glucosidase and β-xylanase) were secreted at the late stage of SSF, but tripeptidyl peptidase sed 2 was proposed as an indispensable protease in SmF or the early stage of SSF. [7] Tripeptidyl peptidase II (TPPII) is the most extensively characterized enzyme, supplementing and sometimes substituting for proteasomal functions. [8] described first symptoms in CLN2 disease, which is caused by mutations in the tripeptidyl peptidase 1 (TPP1)/CLN2 gene, resulting in TPP1 enzyme deficiency and subsequent lysosomal storage. [9]
