Title: Tripeptidyl peptidase II regulates sperm function by modulating intracellular Ca(2+) stores via the ryanodine receptor.
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.
Title: Exploring the active site of tripeptidyl-peptidase II through studies of pH dependence of reaction kinetics.
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 in vivo.
Title: Analysis of the role of tripeptidyl peptidase II in MHC class I antigen presentation in vivo.
These results do not support a generally important role of TPPII for viability and proliferation of transformed cells or their p53-mediated DNA damage response.
Title: Viability and DNA damage responses of TPPII-deficient Myc- and Ras-transformed fibroblasts.
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.

TPPII is important for maintaining normal cellular and systemic physiology, which may be relevant for potential therapeutic applications of TPPII inhibitors
Title: Activation of cellular death programs associated with immunosenescence-like phenotype in TPPII knockout mice.
The data suggest a moderate, predominantly destructive role of TPPII in class I Ag processing.
Title: Analysis of direct and cross-presentation of antigens in TPPII knockout mice.
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.
Title: Need for tripeptidyl-peptidase II in major histocompatibility complex class I viral antigen processing when proteasomes are detrimental.
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.
Title: No essential role for tripeptidyl peptidase II for the processing of LCMV-derived T cell epitopes.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
