What is the function of this protein?
Interferon (IFN)-inducible GTPase that plays important roles in innate immunity against a diverse range of bacterial, viral and protozoan pathogens (PubMed:18025219, PubMed:21551061, PubMed:31964735, PubMed:24739961).  Hydrolyzes GTP to GMP in two consecutive cleavage reactions and predominantly uses GTP and not GDP or GMP as the substrate (PubMed:21551061, PubMed:31689351).  Following infection, recruited to the pathogen-containing vacuoles or vacuole-escaped bacteria and acts as a positive regulator of inflammasome assembly by promoting the release of inflammasome ligands from bacteria (PubMed:24739961).  Acts by promoting lysis of pathogen-containing vacuoles, releasing pathogens into the cytosol (PubMed:24739961).  Following pathogen release in the cytosol, promotes recruitment of proteins that mediate bacterial cytolysis, such as Gm12250/Irgb10: this liberates ligands that are detected by inflammasomes, such as lipopolysaccharide (LPS) that activates the non-canonical CASP4/CASP11 inflammasome or double-stranded DNA (dsDNA) that activates the AIM2 inflammasome (PubMed:24739961).  Also promotes IFN-gamma-mediated host defense against bacterial infections by regulating oxidative responses and bacteriolytic peptide generation (PubMed:21551061).  May help to assemble NADPH oxidase on phagosomal membranes by acting as a bridging protein between NADPH oxidase cytosolic subunits NCF2-NCF4 and the membrane subunits CYBA-CYBB (PubMed:21551061).  Participates along with GBP1 in trafficking monoubiquinated protein cargo to autolysosomes for generating ubiquitin-derived antimicrobial peptides (PubMed:21551061).  Facilitates influenza A virus replication by inhibiting the activation of NF-kappaB and JAK-STAT signaling pathways and the expression of type I, type III interferons and pro-inflammatory cytokines (By similarity).  Confers protection to several pathogens, including the bacterial pathogens Listeria monocytogenes and Mycobacterium bovis BCG as well as the protozoan pathogen Toxoplasma gondii (PubMed:18025219, PubMed:21551061, PubMed:31964735).  Required for disruption of the parasitophorous vacuole formed following T. gondii infection and subsequent killing of the parasite (PubMed:31964735).
