Application
Human dipeptidyl peptidase VIII has been used in a study to identify ERGIC-53 as an intracellular transport receptor of α1-antitrypsin. Human dipeptidyl peptidase VIII has also been used in a study to investigate the cargo selectivity of the ERGIC-53/MCFD2 transport receptor complex.
Biochem/physiol Actions
Dipeptidyl peptidase VIII (DPP8) is a 100 kDa monomeric protein expressed in the cytoplasm. It is a postproline dipeptidyl aminopeptidase that is homologous to DPPIV and fibroblast activation protein (FAP). It hydrolyzes Ala-Pro, Arg-Pro and Gly-Pro. DPP8 has a neutral pH optimum. It may be involved in T-cell activation and immune function as it is similar to DPPIV . It is upregulated during immune activation.
Physical properties
Full length sequence with an N-terminal GST tag
Unit Definition
One unit will hydrolyze 1.0 picomole of Ala-Pro-AMC per minute at pH 7.4 at 25 deg °C

Secretory proteins are exported from the endoplasmic reticulum (ER) by bulk flow and/or receptor-mediated transport. Our understanding of this process is limited because of the low number of identified transport receptors and cognate cargo proteins. In mammalian cells, the lectin

Exit of soluble secretory proteins from the endoplasmic reticulum (ER) can occur by receptor-mediated export as exemplified by blood coagulation factors V and VIII. Their efficient secretion requires the membrane lectin ER Golgi intermediate compartment protein-53 (ERGIC-53) and its soluble

Dipeptidyl peptidase (DPP) IV has roles in T-cell costimulation, chemokine biology, type-II diabetes and tumor biology. Fibroblast activation protein (FAP) has been implicated in tumor growth and cirrhosis. Here we describe DPP8, a novel human postproline dipeptidyl aminopeptidase that is
