==Function== | |||
[[http://www.uniprot.org/uniprot/AIM2_HUMAN AIM2_HUMAN]] Involved in innate immune response by recognizing cytosolic double-stranded DNA and inducing caspase-1-activating inflammasome formation in macrophages. Upon binding to DNA is thought to undergo oligomerization and to associate with PYCARD initiating the recruitment of caspase-1 precusrsor and processing of interleukin-1 beta and interleukin-18. Detects cytosolic dsDNA of viral and bacterial origin in a non-sequence-specific manner. Can also trigger PYCARD-dependent, caspase-1-independent cell death that involves caspase-8 (By similarity). Tumor suppressor which may act by repressing NF-kappa-B transcriptional activity.<ref>PMID:16432157</ref> <ref>PMID:17726700</ref> <ref>PMID:19158679</ref> <ref>PMID:19158676</ref> <ref>PMID:19158675</ref> <ref>PMID:20566831</ref> | |||
