Protein Structure

UniProt Annotation

Function

Involved in the inhibition of the inflammatory response. Acts as a negative regulator of the Toll-like receptors (TLRs)- mediated inflammatory innate response by stimulating the tumor necrosis factor alpha-induced protein TNFAIP3 expression via reactive oxygen species (ROS) in LPS-tolerized macrophages. Involved in antimicrobial response of innate immune cells; IRG1- mediated itaconic acid production contributes to the antimicrobial activity of macrophages. Plays a role in the embryo implantation. {ECO:0000269PubMed:14500577, ECO:0000269PubMed:23609450, ECO:0000269PubMed:23610393}.

Subcellular Localization

Mitochondrion {ECO:0000269PubMed:19014335}.
