Superfamily: Dipeptidylpeptidase IV, N-terminal domain

Structural domains comprising this superfamily share the structure of the N-terminal beta propeller domain of dipeptidylpeptidase IV, a multifunctional type II transmembrane serine peptidase. This enzyme contributes to the regulation of various physiological processes, including blood sugar homeostasis, by cleaving peptide hormones, chemokines and neuropeptides after a proline or alanine at amino acid position 2 from the N terminus PMID:14718659. Dipeptidylpetidase IV also serves as the costimulatory molecule in T cell activation and is an associated marker of autoimmune diseases, adenosine deaminase-deficiency and HIV pathogenesis PMID:1352530,PMID:20959412,PMID:21856036.
