Development, evaluation and application of tripeptidyl-peptidase II sequence signatures

Tripeptidyl-peptidase II (TPP II) is a cytosolic peptidase that has been implicated in fat formation and cancer, apparently independent of the enzymatic activity. In search for alternative functional regions, conserved motifs were identified and eleven signatures were constructed. Seven of the signatures covered previously investigated residues, whereas the functional importance of the other motifs is unknown. This provides directions for future...
