The function of ENSG00000134900 (TPP2, tripeptidyl peptidase 2) is as follows. Cytosolic tripeptidyl-peptidase that releases N-terminal tripeptides from polypeptides and is a component of the proteolytic cascade acting downstream of the 26S proteasome in the ubiquitin- proteasome pathway (PubMed:25525876, PubMed:30533531). It plays an important role in intracellular amino acid homeostasis (PubMed:25525876). Stimulates adipogenesis (By similarity). {ECO:0000250|UniProtKB:Q64514, ECO:0000269|PubMed:25525876, ECO:0000269|PubMed:30533531}.
