Descriptions

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 form

Supplied as a solution in 40 mM Tris-HCL, pH 8.0, 110 mM NaCl, 2.2 mM KCl, 16 mM Glutathione, 3 mM DTT and 20% glycerol.

Physical properties

Full length sequence with an N-terminal GST tag

Unit Definition
