DPP4 - dipeptidyl peptidase 4 Gene
Also Known as CD26; ADABP; ADCP2; DPPIV; TP103
Species: Homo sapiens
About DPP4
This gene has 23 transcripts (splice variants), 286 orthologues and 6 paralogues. Biased expression in small intestine (RPKM 70.7), placenta (RPKM 57.1) and 13 other tissues.
Summary
The DPP4 gene encodes Dipeptidyl Peptidase 4, which is identical to Adenosine Deaminase complexing protein-2, and to the T-cell activation antigen CD26. It is an intrinsic type II Transmembrane Glycoprotein and a serine exopeptidase that cleaves X-proline dipeptides from the N-terminus of polypeptides. Dipeptidyl Peptidase 4 is highly involved in glucose and Insulin metabolism, as well as in immune regulation. This protein was shown to be a functional receptor for Middle East respiratory syndrome coronavirus (MERS-CoV), and protein modeling suggests that it may play a similar role with SARS-CoV-2, the virus responsible for COVID-19.
