    basic FUNCTION
  • capable of cleaving the peptide bond after a penultimate proline residue
  • T cell activation and immune function
  • involved in cleavage of the N-terminal two residues of
  • CXCL10, CXCL11 and CXCL12
  • influence cell-extracellular matrix interactions, and thus may regulate tissue remodeling
  • physiological role of DPP8, DPP9 in the male reproductive system
  • biological roles for DPP8 and DPP9 in lymphocyte activation and apoptosis and in hepatocytes during liver disease pathogenesis
  • DPP8 and DPP9 are involved in multiple cellular pathways including antigen maturation, cellular homeostasis, energy metabolism, and cell viability
  • importance of DPP8 and DPP9 on adipogenesis
  • DPP8 and DPP9 are intracellular N-terminal dipeptidyl peptidases (preferentially postproline) associated with pathophysiological roles in immune response and cancer biology
  • regulates cell proliferation, apoptosis, migration and invasion during cancer progression
  • promotes the progression of cervical cancer

    small molecule
    protein
  • DPP9 and DPP8, associate with HRas, a key signal molecule of the EGF receptor signaling pathway, suggesting an important signaling role of DPP9 in the regulation of survival and proliferation pathways
  • UBA2 interacts with both SUMO1 and SUMO2, both DPP8 and DPP9 showed a strong preference toward SUMO1 binding
  • cytosolic serine dipeptidyl peptidases DPP8 and DPP9 suppress inflammasome activation upstream of NLRP1 and CARD8 in human keratinocytes and peripheral blood mononuclear cells
