Novel interactions of TPPII, p53 (zeige TP53 Antikörper), and SIRT7 (zeige SIRT7 Antikörper) presented in this study might contribute to the knowledge of the regulatory effects of these proteins on apoptotic pathways and to the understanding mechanisms of aging and lifespan regulation.
TPP2 mediates many important cellular functions by controlling ERK1 (zeige MAPK3 Antikörper) and ERK2 (zeige MAPK1 Antikörper) phosphorylation.
Early-onset Evans syndrome, immunodeficiency, and premature immunosenescence associated with TPP2 deficiency have been described in two consanguineous siblings.
Study found that autosomal recessive TPP2 mutations cause recurrent infections, autoimmunity, and neurodevelopmental delay in humans.
TPPII, MYBBP1A (zeige MYBBP1A Antikörper) and CDK2 (zeige CDK2 Antikörper) form a protein-protein interaction network.
Previously unknown differences between TPP II orthologues and subtilisin as well as features that might be conserved within the entire family of subtilisin-like serine peptidases.
Study showed that overexpression of Tripeptidyl peptidase II (TPP2) occurs frequently during oral carcinogenesis and might be associated with the progression of Oral Squamous Cell Carcinoma (OSCC) via Spindle Assembly Checkpoint(SAC (zeige ADCY10 Antikörper)) activation.

Current knowledge about TPPII with a focus on structural aspects.
Results suggest an important function of TPPII in the maintenance of viral growth and may have implications for anti-viral therapy.
Data indicate that TPPII can regulate sperm maturation by modulating intracellular Ca(2 (zeige CA2 Antikörper)+) stores via the type 3 RyR (zeige RYR1 Antikörper).
Tripeptidyl peptidase II is crucial for nucleoprotein epitope generation during major histocompatibility complex class I complex viral antigen processing both in the presence and absence of lactacystin-sensitive proteasome action.
TPPII is not generally required for the production of major histocompatibility class I-restricted peptides, but presentation of some peptides can be negatively affected by TPPII.
Data show that mice that were homozygous for an insertion in the Tpp2 locus were embryonic lethal and Tpp2 heterozygous mutants were lean compared with wild-type littermates, although food intake was normal.
The data suggest a moderate, predominantly destructive role of TPPII in class I Ag processing.
TPPII is important for maintaining normal cellular and systemic physiology, which may be relevant for potential therapeutic applications of TPPII inhibitors
These results do not support a generally important role of TPPII for viability and proliferation of transformed cells or their p53 (zeige TP53 Antikörper)-mediated DNA damage response.
These data indicate that while TPPII contributes to the trimming of peptides with very long N-terminal extensions, TPPII is not essential for generating most MHC class I-presented peptides or for stimulating CTL responses to several Ags (zeige GLA Antikörper) in vivo.
a systematic kinetic analysis of wild type Drosophila melanogaster TPPII and five point mutants of the double-Glu (zeige SLC2A1 Antikörper)-motif (E312/E343) involving natural substrates were performed.
The structure suggests a model for activation of TPP II involving the relocation of a flexible loop and a repositioning of the active-site serine, coupling it to holocomplex assembly and active-site sequestration.
The 150 kDa subunits of TPPII form a superstructure composed of 2 segmented & twisted (zeige POMT2 Antikörper) strands. Each strand is 12.5 nm in width & composed of 11 segments that enclose a central channel.
the unique spindle form of the holo-complex of TPP II represents an assembly motif stabilizing a highly active state
The purification and characterization of tripeptidyl peptidase II from Arabidopsis thaliana is reported.
This gene encodes a mammalian peptidase that, at neutral pH, removes tripeptides from the N terminus of longer peptides. The protein has a specialized function that is essential for some MHC class I antigen presentation. The protein is a high molecular mass serine exopeptidase\; the amino acid sequence surrounding the serine residue at the active site is similar to the peptidases of the subtilisin class rather than the trypsin class.
