About DPP9

Cytogenetic location: 19p13.3 Genomic coordinates (GRCh38): 19:4,675,227-4,723,842 (from NCBI)

This gene has 29 transcripts (splice variants), 255 orthologues, 6 paralogues and is associated with 1 phenotype. Ubiquitous expression in spleen (RPKM 7.8), appendix (RPKM 7.5) and 25 other tissues.

Summary

This gene encodes a protein that is a member of the S9B family in clan SC of the serine proteases. The protein has been shown to have post-proline dipeptidyl Aminopeptidase activity, cleaving Xaa-Pro dipeptides from the N-termini of proteins. Although the activity of this protein is similar to that of Dipeptidyl Peptidase 4 (DPP4), it does not appear to be membrane bound. In general, dipeptidyl peptidases appear to be involved in the regulation of the activity of their substrates and have been linked to a variety of diseases including type 2 diabetes, obesity and Cancer. Several transcript variants of this gene have been described but not fully characterized. [provided by RefSeq, Jul 2008]
