Secondry Information

Protein Function cystein cathepsin; involved in a normal cellular protein degradation and turnover; aminodipeptidase
Biochemical Properties Cysteine cathepsins are optimally active in a slightly acidic pH and are mostly unstable at neutral pH; exhibit broad specificity, cleave substrates preferentially after basic or hydrophobic residues; E-64 is a non-selective inhibitor of all the cysteine cathepsins, with the exception of cathepsin C, which is only weakly inhibited
Significance in milk DPP4 is a key enzyme in intermediary metabolism by regulating important glycemic pathways; expression of DPP4 decreases with the onset of lactation
PTMs Glycosylated: four glycans
