[https://www.uniprot.org/uniprot/IIGP1_MOUSE IIGP1_MOUSE] GTPase with low activity. Has higher affinity for GDP than for GTP. Plays a role in resistance to intracellular pathogens. Required for disruption of the parasitophorous vacuole formed following T.gondii infection and subsequent killing of the parasite. Mediates resistance to C.trachomatis infection by targeting bacterial inclusions to autophagosomes for subsequent lysosomal destruction.<ref>PMID:11907101</ref> <ref>PMID:16304607</ref> <ref>PMID:19242543</ref> <ref>PMID:12732635</ref>

Interferon-inducible p47 GTPases are critical mediators of cell-autonomous resistance against several intracellular pathogens. Here we present the first crystal structure of a member of this novel GTPase family, IIGP1, in its nucleotide-free, GDP-, and GppNHp-bound form. The structure shows a Ras-like G domain between an N-terminal three-helix bundle and a complex system of C-terminal helices and loops. Sequence comparison and secondary structure prediction suggest the IIGP1 structure to be a valid model for the p47 GTPase family. The IIGP1 crystals contain a noncrystallographic dimer. We show that the dimer is required for cooperative GTP hydrolysis and GTP-dependent oligomerization of IIGP1. We also present the GDP- and GppNHp-bound monomeric structures of two dimer interface mutants. Our structures direct approaches to the analysis of the catalytic mechanism of IIGP1 and provide a coherent basis for structure-function studies aimed at elucidating the mechanistic basis of pathogen resistance caused by these enigmatic GTPases.
