CC -!- FUNCTION: Dipeptidyl peptidase that cleaves off N-terminal dipeptides
CC from proteins having a Pro or Ala residue at position 2
CC (PubMed:11012666, PubMed:12534281, PubMed:12662155, PubMed:15039077,
CC PubMed:15664838, PubMed:20536396, PubMed:29382749). Acts as a key
CC inhibitor of caspase-1-dependent monocyte and macrophage pyroptosis in
CC resting cells by preventing activation of NLRP1 and CARD8
CC (PubMed:27820798, PubMed:29967349, PubMed:32796818). Sequesters the
CC cleaved C-terminal part of NLRP1 and CARD8, which respectively
CC constitute the active part of the NLRP1 and CARD8 inflammasomes, in a
CC ternary complex, thereby preventing their oligomerization and
CC activation (PubMed:34019797, PubMed:33731929, PubMed:33731932). The
CC dipeptidyl peptidase activity is required to suppress NLRP1 and CARD8;
CC however, neither NLRP1 nor CARD8 are bona fide substrates of DPP8,
CC suggesting the existence of substrate(s) required for NLRP1 and CARD8
CC inhibition (By similarity). {ECO:0000250|UniProtKB:Q86TI2,

CC and by di-isopropylfluorophosphate. Specifically inhibited by
CC isoindoline derivatives (PubMed:11012666, PubMed:12662155,

CC selective inhibitor, which triggers pyroptosis in monocytes and
