Sequence statusComplete.
Sequence processingThe displayed sequence is further processed into a mature form.
Protein existenceEvidence at protein level.

General annotation (Comments)

Function

Removes N-terminal dipeptides sequentially from polypeptides having unsubstituted N-termini provided that the penultimate residue is proline. Plays a role in T-cell activation.

Catalytic activity

Release of an N-terminal dipeptide, Xaa-Yaa-|-Zaa-, from a polypeptide, preferentially when Yaa is Pro, provided Zaa is neither Pro nor hydroxyproline.

Subunit structure

Homodimer or heterodimer with Seprase (FAP). Ref.13 Ref.14 Ref.15 Ref.16

Subcellular location

Dipeptidyl peptidase 4 soluble form: Secreted.

Cell membrane; Single-pass type II membrane protein.

Tissue specificity

Expressed in the poorly differentiated crypt cells of the small intestine as well as in the mature villous cells. Expressed at very low levels in the colon. Ref.9

Post-translational modification

The soluble form (SDPP) derives from the membrane form (MDPP) by proteolytic processing.

Sequence similarities

Belongs to the peptidase S9B family. DPPIV subfamily.
