Anti-DPP9 antibody - Catalytic domain,Abcam,AB42080

Target data Dipeptidyl peptidase that cleaves off N-terminal dipeptides from proteins having a Pro or Ala residue at position 2 (PubMed : 12662155, PubMed : 16475979, PubMed : 19667070, PubMed : 29382749, PubMed : 30291141, PubMed : 33731929, PubMed : 36112693). Acts as a key inhibitor of caspase-1-dependent monocyte and macrophage pyroptosis in resting cells by preventing activation of NLRP1 and CARD8 (PubMed : 27820798, PubMed : 29967349, PubMed : 30291141, PubMed : 31525884, PubMed : 32796818, PubMed : 36112693, PubMed : 36357533). Sequesters the cleaved C-terminal part of NLRP1 and CARD8, which respectively constitute the active part of the NLRP1 and CARD8 inflammasomes, in a ternary complex, thereby preventing their oligomerization and activation (PubMed : 33731929, PubMed : 33731932, PubMed : 34019797). The dipeptidyl peptidase activity is required to suppress NLRP1 and CARD8; however, neither NLRP1 nor CARD8 are bona fide substrates of DPP9, suggesting the existence of substrate(s) required for NLRP1 and CARD8 inhibition (PubMed : 33731929).
