CC -!- FUNCTION: Cis-aconitate decarboxylase that catalyzes production of
CC itaconate and is involved in the inhibition of the inflammatory
CC response (PubMed:23609450, PubMed:23610393). Acts as a negative
CC regulator of the Toll-like receptors (TLRs)-mediated inflammatory
CC innate response by stimulating the tumor necrosis factor alpha-induced
CC protein TNFAIP3 expression via reactive oxygen species (ROS) in LPS-
CC tolerized macrophages (PubMed:23609450). Involved in antimicrobial
CC response of innate immune cells; ACOD1-mediated itaconic acid
CC production contributes to the antimicrobial activity of macrophages
CC (PubMed:23610393). Involved in antiviral response following infection
CC by flavivirus in neurons: ACOD1-mediated itaconate production inhibits
CC the activity of succinate dehydrogenase, generating a metabolic state
CC in neurons that suppresses replication of viral genomes (By
CC similarity). Plays a role in the embryo implantation (By similarity).

CC Reaction=cis-aconitate + H(+) = CO2 + itaconate; Xref=Rhea:RHEA:15253,

CC Evidence={ECO:0000269|PubMed:23610393};
CC -!- SUBCELLULAR LOCATION: Mitochondrion {ECO:0000250|UniProtKB:P54987}.
CC -!- TISSUE SPECIFICITY: Expressed in LPS-tolerized macrophages (at protein
CC level). Expressed in peripheral blood mononuclear cells (PBMCs),
CC microglia and macrophage cells. {ECO:0000269|PubMed:23609450,
CC ECO:0000269|PubMed:23610393}.
CC -!- INDUCTION: Up-regulated after lipopolysaccharide (LPS) stimulation. Up-
CC regulated in LPS-tolerized macrophage by LPS. Up-regulated in
CC peripheral blood mononuclear cells (PBMC) of patient after acute
CC sepsis. {ECO:0000269|PubMed:23609450, ECO:0000269|PubMed:23610393}.
CC -!- SIMILARITY: Belongs to the PrpD family. {ECO:0000305}.
