The protein encoded by the ''DPP4'' gene is an [[enzyme]] expressed on the surface of most cell types and is associated with immune regulation, [[signal transduction]], and [[apoptosis]]. It is a type II transmembrane [[glycoprotein]], but a soluble form, which lacks the intracellular and transmembrane part, is present in blood plasma and various body fluids. DPP-4 is a [[serine]] [[exopeptidase]] that cleaves X-proline or X-alanine [[dipeptide]]s from the [[N-terminus]] of [[polypeptide]]s. Peptide bonds involving the cyclic amino acid proline cannot be cleaved by the majority of proteases and an N-terminal X-proline "shields" various biopeptides. Extracellular proline-specific proteases therefore play an important role in the regulation of these biopeptides.</div>FuzzyBot
